1. Fort Sill, Comanche Co, Reynolds Army Community Hospital: On
Second floor... "Felt the floor moving (like someone was shaking the building)
saw the walls of my cubicle moving".

2. Fort Sill, Comanche Co., Bld 700: "Inside, 2d floor... Sitting at desk
talking on the phone... [heard] Slight rumble... Entire building seemed to
shake north to south. This building is very sturdand demonstrates little
movement even during high intensity artillery firing here at Ft Sill.
Party on the other end of the phone at **** ** Birch Place, Lawton, reported
feeling the same thing, and seeing the house plants sway.

3. Fort Sill, Comanche Co., McNair Hall, Building 455: "It sounded like distant
thunder or an artillery barrage, which often occurs at Fort Sill. I felt my 
chair shake and heard my office windows rattling, which is unusual. It would
take a very large artillery barrage or Air Force bomb drop to cause that 
much shaking. ... a woman called our office to say it caused a crack in the
foundation of her house, and wanted to know if Fort Sill "had dropped a bomb."
We told her no"

4. Fort Sill, Comanche Co., Building 1459, Punch Bowl Road: "Standing near
work bench. Sounded like field artillery, felt two seperate small pulses
of vibration in the floor."

5. Lawton, Comanche Co., 1 mile north of McClung's Store on Hwy 58:
"ground floor... sitting on the couch... the sound was very loud, like several
jet aircraft passing over just 100 feet over the house. the quake passed
from northeast to southwest with a rolling motion that lasted about 1 and 1/2
1/2 seconds. i have experienced other quakes in panama and hawaii, as well
as the quake in this area of OK several yearsago. i would describe this as a
moderate quake, not scary, just surprising. ... the house shook thoughout
the quake. it kind of rolled like the rolling sensation of the quake rather
than a hard, shaking motion. ... **one picture knocked over on a dresser.**"

6. Ft. Sill, Comanche Co., Building 1950 Barbour Rd: "1 st floor.
Working with my computer. setting down. [heard] distant thunder,
Chair moved some. screen of computer moved."

office. heard windows rattle building shook a little"

8. Ft. Sill, Comanche Co., Hamilton Road: "2nd [storey] Sitting at my computer.

being used. Felt a small tremor similiar to that of the Seattle Quake of Feb.
01".

15. Elgin, Comanche Co., North of football field.: "I had just waken up and
was lying in bed. I first heard the windows rattle. There was no sound of
thunder... usually the field artillery from fort sill rattles the windows,
but there was no sound of the artillery hitting as usual. After the windows
began to rattle, the bed began to shake while I was lying in it. It woke up
my cat who is usually oblivious to the sound of artillery shelling by Ft.
Sill. I think it was the bed moving that startled her."

16. Ft. Sill, Comanche Co., Searby Circle: "working at my computer in my
[first floor] office... heard a rumbling sound...it was like rolling
thunder which faded out in about 4-5 seconds, like a rumble moving through.
I felt like the house was swaying back and forth and tho I'm sure it didn't,
it felt like my chair (on wheels) moved back and forth."

23. Ft. Sill, Comanche Co., Building 3040, near junction of Ft Sill Blvd and
Austin Road: "Ground floor, I was sitting at my Test Bench, working on a
piece of test equipment and speaking with a co-worker. A single distant boom,
like one of the new Daisy Cutter Bombs had been dropped somewhere NorthEast
of my location at a distance of approximately 5 miles away. The building shook
with sounds of the structure supports shaking in the attic. I have felt many
earthquakes while in Alaska and this one was different. It sounded more like a 
single but huge detonation from a distance. No noticible subsequent vibration
at all. My test bench moved, (swayed East to West once), this bench weighs
more than 300 pounds. *The plate glass window to my west actually looked
like pressure had pushed it outward and then back again, singularly. No
breakage"

24. Lawton, Comanche Co., Holy Family Catholic Church NW 82nd: "Ground floor,
at work, sitting at my desk....Two people [in an adjoining room did not feel
anything]. The floor moved under my feet and I heard what I thought at the
time was a boom that I attributed to shelling at Ft. Sill. I should have
realized what it was because the last one we had here in Lawton I was at
home sitting in my office and the complete floor rippled under my feet and
I called my brother and told me we had an earthquake.  It must have been more
intense the other time, I felt the floor moved under my feet.  Not a ripple
but a definite movement.

 {OGS note: "the other time" probably refers to a 1998 APR28
  magnitude 4.2 earthquake in Comanche County}

25. Lawton, Comanche Co., Elgin High School: "First floor, I was sitting
at my desk calling roll. The sound was not that different than when they
are shooting on post, so I didn't think it was unusual. It soundedlike
distant thunder. I could feel a vibratiion in my feet and in my desk.
None of the items on my desk were shaking, nothing fell of my desk or
off the shelves of my classroom."

26. Lawton, Comanche Co., Wildwood Road: "[home, first floor, working
at computer] Heard deep rumble, like thunder or artillery fire. Felt 
strong shock of several seconds. Felt the strong tremor of the earth through
concrete slab of home."

feel anything. Heard an extremely loud boom sound, at the time someone
had "shot out" during training exercise."

28. Lawton, Comanche Co., east of Crosby Park School: "2nd floor working
on the computer, heard a rumbling and the building like moved in slow
motion, a shake sort of. I swayed cause I stood up about that time." 

29. Lawton, Comanche Co., On highway 58 across from Lake Lawtonka: "1st
floor, sleeping, Sounded like a boom,like Fort Sill had dropped a bomb in

"sitting down , suvey of mathamtics had just started. heard nothing, myself
and two or three people felt a rumble, like something really big had been
dropped either on the same floor or on the one below. We only felt it for a
few seconds."

32. Walters, Cotton Co., East Kansas Ave: "first floor, lying in bed, Heard
a thunderlike noise, thought it was strange to hear thunder on a clear day,
*then I heard something falling on the floor in the kitchen*.

33. Ft. Sill, Comanche Co., NE of Old Post Chapel: "In my home living room,
1st/only one level, sitting down at computer, sounded like not-so-distant
thunder, - chair rocked, house shook, small dog laying on patio was bounced
around like a jumping bean, nothing fell off shelves, no pictures fell from
the walls."

34. Lawton, Comanche Co., one mile S. of Ft. Sill: "home, first floor, sitting
on couch watching TV, I heard a rumbling sound as if it might of been
something that fort sill was doing, but it was really unusual., The whole
house shook in a way it never has.  I live close to Fort sill, so I am used
to the shooting out there, but this was nothing [by comparison]. It was
like the whole house just got up and moved. The furniture shook, knick-knacks
trembled,  T.V. shook, [nothing out of place]."

35. Duke, Jackson Co., Oklahoma: "Sitting in the living room of my single wide
Trailer house watching television, Nothing was heard, My husband and I felt
the house shake for about three seconds. Nothing severe just a slight shaking
of the whole house."

36. Lawton, Comanche Co., Hugh Bish Elementry: "4,5,6 graders were in the
cafeteria sitting down watching mrs. sherries dancers. rumbling sound,
i felt it on the ground."

37. Indiahoma, Comanche Co., west of intersection of new Hwy 62 and Rt 115:

out of the ordinary. The wind was blowing outside. I felt the whole house 
tremble for a second or two."

38. Lawton, Comanche Co., sw of Pioneer Park Grade School: "I was sitting on
my bed when I felt the floor shake and heard a lot of noise that I was sure
was not the normal Ft, Sill firing, sitting on my bed watching tv and felt the
bed shake and heard noise, sound that was familiar to what we hear when Ft.
Sill is firing but much more intense which told me it was probably an
earthquake because it was the same as what I felt and heard in 98."

{OGS note: 98 probably refers to a magnitude 4.2 earthquake on 1998 APR28
 in Comanche County.}

39. Meers, Comanche Co., four miles from Meers: "at home, ground floor,
Surfing the Internet, Sounded like a very long impact burst from Ft. Sill.
Lasted several seconds rumbled very much like an Artillery blast in the
distance, The house shook throughout, could hear and feel an airburst."

40. Ft. Sill, Comanche Co., field artillery training center: "I actually
thought it was artillery impacting... but this was a much larger
concussion. It reminded me of years ago when the 8" howitzer would shoot
and the ground would shake fairly severely... This 'concussion'  actually
made me look out the window and I did notice some vibration of the area...
At that I just thought it must have been a simultaneous impact of artillery.
I definitely felt the building shake, but only for a short duration."

{OGS note: several years back atmospheric conditions caused a "time on
target" simultaneous impact at Ft. Sill to be HEARD as far away as
Oklahoma City. But, except for a tiny signal at the seismograph in Meers,
Comanche Co., there were no detectable seismic (earth) vibrations}

41. Lawton, Comanche Co., Taft School: "i was writing a report in my desk,
desks shook, my pencil move back and forth, all the desk were outtta order"

42.  Ft. Sill, Comanche Co., near the New Post Chapel: "I was sleeping lightly 
in a chair. It was a very loud rumble much different from the artillery
fire that we are accustomed to... There were very loud vibrations of all
of the things on our shelves. We even heard the springs of the recliner that
I was in rattle. It rattled enough to wake me up in the chair. It felt as
though someone was just shaking the foundation of our house and all I could
think to do was grab onto the arms of the chair."

43. Elgin/Porter Hill, Comanche Co., east of Porter Hill:" lower floor
standing at kitchen sink, Thought Ft. Sill had missed its target.  Walls of
house actually moved.  House is 80 years old... Walls of addition in 1963
seemed to "breathe" - per husband.  Ran outside to see where the missle
had hit!"

44. Ft. Sill, Comanche Co., 2 kilometers NE of the Control tower on the Ft. 
Sill Airfield, Searby Hall: "3rd floor sitting at my office desk, I heard a
loud roar and thought at first it was artillery shells impacting on West
Range realized that it was much louder than artillery shells at that distance
and assumed it to be something else. The whole buidling, Searby Hall, shook.
I could feel my desk, chair etc, rumbling for a couple seconds."

45. Ft. Sill, Comanche Co., Building 2913 (Corner of Craig and Custer Roads,:
ground floor, Using computer/typing info, I heard what sounded like ordnance
exploding in the distance...it was louder than the regular howitzer ordnance
explosions. It was more like the exploding ordnance dropped by the air force
bombers during fire power demonstrations at Fort Sill. Simultaneously, my
keyboard and monitor began vibrating. My chair also vibrated."

46. Lawton, Comanche Co., North of School House Slough on Lake Lawtonka:
"Home. Ground floor. Using computer. Felt one strong shake, heard a loud boom.
Felt like chair dropped. *Chandelier swayed.*"

In reply to an Email request the person sending report 46. wrote:
   The chadelier swung about 4 inches each way. It is about 3 feet in
length. 
It takes about 1 to 1 1/2 seconds to complete a swing from one side to the 
other.
   I lived in the San Francisco Bay Area for 42 years and was only about 12
miles from the Loma Prieta quake epicenter in 1989.

47. Lawton, Comanche Co., west of liberty heights baptist church: "I was
outside hanging laundry on the clothsline. I heard what sounded like a huge
explosion... I felt the earthshake for what may have been a count to 8.
*The water in a nearby cat bowl sloshed around, and the basket of cloths pins
suspended from the clothsline rope shook right in front of my face.
I have a candle in a jar that was lit at the time; the wax that was liquid
around the base of the flame had sloshed up the sides of the glass, and the
flame had been snuffed out by the wax sloshing over it.*"

48. Lake Lawtonka, Lawton, Comanche Co., N from school house slough at lake
lawtonka: "First floor. I was sitting at my computer in my home...
The ground beneath my feet roared like a huge exlosion had occured...
I lived in California for 20 years and experienced many earthquakes but I did
not assoicated this with a earthquake until I heard it on the news. felt the
earth roar beneath my feet and rumble. no swaying. *some items were crooked
on the wall.*"

49. Elgin, Comanche Co., north of porter hill: "first floor, Was on my computer
... *my chair shook and some pictures fell off the wall and light cover in 
bathroom fell off.*"

50. Porter Hill, Comanche Co., About 5 1/2 miles west of elgin high school:
"standing in the kitchen area of the convenience store I manage. I heard a 
very loud boom. It was like a sonic boom. There was nothing distant about
it. It felt like it was right on top of us. The building shook. I *almost
lost my balance". I thought a semi truck had just hit the building... *Some
of the dishes were shaken off the shelves onto the floor. I went into my office
and noticed particles of debris a little bit bigger than dust particles on my
counter that had fallen from the ceiling tiles.*"

51. Lawton, Comanche Co., N. W. Cherry: "1st Sitting in my liveing room. I
heard rumble like thunder. The wall behind me popped and The couch, I was
sitting on moved under neath me. Saw the room move. My dog was a sleep, she
came running down the hall to bark, she looked from side to side, trying to
figure what happened."

52. Lawton, Comanche Co., Near the Westwood school district: "I was laying
in bed, and the ground rumbled, tins fell from dresser, heard nothing but a
tin or two (decorative and small) fall  from the top of my tripple dresser
onto the floor, as the shaking or rumbling or vibrating feeling was going
on, for about 10 to 15 seconds.. knick knack fell, small light weight tins.
knick knacks displaced....just the light weighed ones"

53. Ft. Sill, Comanche Co., 1.2 miles North of Sheridan Road School:
"Sitting at my desk Ground floor Working on flowcharts on Computer At first
I thought it may have been an extremely large charge (explosives) set off
then when it continued to build I knew it had to be a quake, don't remember
how long it lasted - seemed like a long time - I know it was only  two or
three seconds, Building shook *couple of pictures fell off the wall, water
in my cup vibrated (no splashing.* pictures were in disarray".

54. Lawton, Comanche Co., Wichita Mtn Estates: "main floor On the computer
At first I thought that road construction on Hwy 49 was blasting. It was
very loud. The monitor seemed to bounce. Windows and dishes rattled, but
nothing broke. The house shook."

55. Paradise Valley, Comanche Co., N of Anns Country Kitchen: "first floor
sitting down, watching TV Loud Boom (much greater, than from nearby
Ft.Sill), then everything in house started to shake and rattle, house shook
throughout, as if it was moving around, off the foundation, hanging plants
started swaying, but mostly they shook, several pictures on the walls were
moved, as well as pictures and some knick-kmacks on the shelves....some as
far as 3 inches."

56. Elgin, Comanche Co., East of Assembly of God Church: "Ground Working at
my computer Heard a boom like an explosion, although not extremely loud."

57. Lawton, Comanche Co., south of Tomlinson Junior High: "first walking
across living room Heard rattle in windows, almost like thunder, or a
misfire on Ft. Sill but the tremors and the sound came at the same time
instead of delayed with shelling from the post the house shook throughout,
the floor shook so that my legs felt shaky"

58. Ft. Sill, Comanche Co., about 1 mile north of Sheridan gate: "first
floor of three Sitting at my desk working on the computer Being at Ft. Sill,
there's constantly booming going on from the artillery being fired.  This
was different.  This was a deep rumble that was way different from any
artillery that I have heard before.  It also sounded like the walls cracked,
but I didn't seeing any evidence of cracking. It shook the whole building. I
have never experienced any other earthquake before this one, and I can
assure you that this is what it had to be because I have been around
artillery for 10 years and I have never felt anything like this."

59. Lawton, Comanche Co., south of Eisenhower High School: "ground level
Sitting in a fairly heavy office type chair on rollers on carpet looking at
the computer. I had the sensation someone had grabbed my chair and was
shaking it. I turned my head by reflex to see who was shaking it although I
knew noone else was in the room and felt silly for my action. I looked back
at the computer and the screen was shaking from side to side (north to
south).  I watched it for approx. 3 seconds and it stopped moving. The base
of the monitor did not move on the desktop during this time.

60. Apache, Caddo Co., down town: "I was sitting in the livingroom watching
T.V. on the first floor I live in a two story house and I felt the whole
house shake and rumble but I did not hear any sounds except for my house
squeeking and one of my walls cracked. The rumble of the quake made the
water in my fish tanks ripple for a few seconds and I felt the whole house
rumble. It only lasted for a few seconds. I noticed that both of the
fishtanks in my house rippled for a few seconds. A few nick-kacks were
knocked off the wall on the South side of the house. There is a new crack
above one of the doors in the kitchen.

61. Lawton, Comanche Co., NE of Pioneer Park School: "I was chatting on the
computer with a friend It didn't quite fell like Ft. Sill was firing.  It
felt like someone in the a downstairs condo was doing work on their condo or
someone was working on the siding of the building. I felt the floor shake.
It was different than when Ft. Sill shoots off their guns.  It was like
there was someone hammering on the outside of the building or underneath my
floor.  When Ft. Sill shoots their guns there is more of a boom and a sturdy
shake.  When I felt this I mentioned to the girl that I was chatting with
that I had to get up quick and see what was going on. I have a seizure
response dog and he was up here with me and he kinda looked up like what is
going on before I felt it.

62. Lawton, Comanche Co., near Howell School: "sitting at the table talking
on the phone felt the floor move;seen things on my table move. house shook
knick-knacks tremble on my kitchen table"

63. Elgin, Comanche Co., 3 miles from Porter Hill: "sitting at my dining
table reading the morning paper. I heard what I at first thought was an
explosion of great magnitude.  It rumbled VERY loudly like it came in 3 or 4
waves very close together.  The vases on top of my china cabinet, directly
in front of me, wobbled and I was afraid they were going to fall over.  The
patio door, windows and chandelier and ceiling fans shook. Because I first
thought of it as an explosion, I immediately ran outside to see if I could
see a smoke plume anywhere.  I live very high on a hill and can see for
miles in all directions.  I didn't see any smoke so I went in and called
KSWO and asked if they had had any reports of a huge explosion and that's
when I was first told it was an earthquake.  I lived in Monterey, CA for 18
months in 1983-84 and felt several quakes there.  This was VERY different
than those.  Those were much gentler.  I don't remember feeling this quake
for more than 5 or 6 seconds because I got up and ran outside.  I told my
husband later, that if the quake here had lasted a whole minute like it did
for the first few seconds,that I truly believe it would have torn the house
down.  This was so different from the quakes in CA that I don't know that,
without the news reports and such, I would have even figured out that it was
an earthquake.  Maybe if I had sat still longer I would have.  I was very
scared and shaky, which is very abnormal for me. I did notice, for the first
time, a small crack in the brick on the east side of my house that goes from
the bottom left corner of the window almost to the foundation.  The house is
just over 2 years old, so it could have just been normal settling and we
just never noticed it before."

64. Lawton, Comanche Co., north of Brockland Elementary School: "sitting at
my dining room table working on some paper work. heard a sound like Ft. Sill
traing with bombs, but it was much loader and stronger then normal. I felt
the table and the floor under my feet shake."

65. Ft. Sill, Comanche Co., BLDG 2255: "sitting down working on computer
heard nothing computer shook and all items on my desk shook. Floor felt like
it was in a waving motion. liquids in bottles did slosh around."

66. Medicine Park, Comanche Co., Wichita Mountain Estates:, "1st floor
Sleeping Thunder, maybe exploded furnace. House shook suspended plants,
dishes falling picture were crooked on the wall,knick-knacks displaced books
on the floor. ceilind cracked."

67. Medicine Park, Comanche Co., Wichita Mountain Estates:, "1st floor of 1
story Eating lunch at the kitchen table At first I thought the troops were
firing on Ft Sill and the rounds were landing out of the safety fan.
Windows rattled for a lot longer than is caused by artillery.  The floor
shook under my feet.  This all went on for 4-5 seconds."

68. Lawton, Comanche Co., Lee Blvd: "first Lying in bed watching TV I heard
a vibration/movement in the southern wall behind my head  I felt a short
series of about 4 -5 slightly rolling jolts with a definite side to side
movement, west to east."

69. Lawton, Comanche Co., NW Maple Dive: "2nd floor apartment I heard a boom
louder than expected from Ft. Sill artillery.  My apartment building shook.
All my purfume bottles & crystal started to clank together & a picture feel
off the wall.  My cat was scared to death. Picture feel off the wall,
purfumes bottles & crystal clanked & shook, making loud noises. Pictures
were crooked on the walls, one was on the floor.  All knick-knacks were
displaced slightly."

70. Lawton, Comanche Co., south of MacArthur Jr. High, "ground floor Sitting
down watching TV. I heard a sound that I knew was not the usual Ft. Sill
firing. I felt what was more like a jarring than shaking.  It seemed to me
that there was a strong initial jarring which became mild and then a strong,
but not as strong as the initial, jarring.  Nothing fell from the walls or
shelves.  It was almost like my house had been gently dropped.

71. reported by 70. My mother who lives south of Apache on the
Comanche/Caddo county line called to tell me her house shook enough to open
her cabinet doors and her back door which will not close since the quake.

72. Lawton, Comanche Co., west of MacArthur High School: "first story Lying
down on the couch watching TV Heard a rumble almost too low to be heard, felt
the floor shake and  felt a ripple go through the whole room. That all
happened  at the same time, it was over in less than 2 or three seconds. The
entire house shook, so much that I was alarmed. I went and asked my mother
if she felt it and she told me that it was the Fort Sill artillery. I wasn't
convinced, I was sure that I had just felt the shockwave from some kind of
above-ground explosion, so I went  outside to look for a cloud of smoke,
etc. but there was nothing out of the ordinary in any direction. I'm used to
hearing the Fort Sill guns, but this was different."

73. Apache, Caddo Co., north of Boone-Apache grade school: "I was sitting on
the floor of the daycare center I work at tying a childs shoes. I heard
nothing but it felt like the floor was making a wave underneath where I was
sitting "

74. Indiahoma, Comanche Co., Post Oak Creek: "sitting down and watching TV

79. Lawton, Comanche Co., Northwest from Country Mart: "First [floor]
I was sitting in front of my computer, on line, in my residence at the above
address.  My great Pyranees was very nervous for about an hour before the
quake.  She ran into my office right before the quake and looked very scared
and sat as close to me as possible.  This dog also knew when the quake was
coming when we lived in Aurora,CO and was very nervous and not herself all
morning.  This was the earthquake that occurred in Washington in  2000.  I
have not been in Lawton very long and thought this was just another new gun
or shell at Fort Sill.  We have just moved here about six months ago from
Colorado.  I have never heard or felt an earthquake before.
heard:         It sounded like a shell exploding or a frieght train going by
very close and then three separate rolling sounds.  Looking back, I can tell
the difference between the Army and this feeling. heard the sounds and the
windows rattling, but also hear this with Fort Sill, especially at night.
 My furnace went off during the night and the repair man said that many
furnaces were off all over town.  The next time my dog gets these
sensations, I will pay closer attention than I have been.  I  know for sure
she knew the earthquake was coming in Seattle, and I now now she knew
yesterday also, but they also know when a weather front is coming through as
is today and I did not pay enough attention and this quake was not as
powerful as the last one in Washington.  I know she feels them, because in
the first one, she finally settled down and went to sleep after pacing and
being scared and nervous for about three hours and then the news broke on
the TV."

lasted 4 times longer and louder  when the shaking started and it seemed
that it would never stop. At first I thought Ft. Sill had put too much
dynamite into the last bomb but it just kept getting louder and the shaking
stated.  Our house shakes when Ft. Sill is practing but you get used to it.
This you could definitely tell was not the base. My whole desk was  shaking
as well as myself in the chair.
felt:          The entire house shook for at least a minute startling my
daughter Nothing fell off the walls but the chandlier was swaying in the
dining rm where my daughter was and some of the pictures on the wall were
crooked I didn't notice anything before this quake but I told my duaghter
