I was reading online newspaper when it occurred. Never before had Thai political news made me feel dizzy. I was wondering the situation must have been so worrisome that I started feeling sick of it. Looking out of my 19th fl. office, I saw the ground moving side-way and thought I must have been really ill. I then checked with my colleague who were walking pass-by and they suggested I should stop reading political news for a big while!

At approximately 4:45 pm I experienced a swaying sensattion as I sat watching television. It lasted in the vicinity of 10 to 15 seconds. I realized that I was feeling the effects of an earth tremor but not the those of a nearby earthquake.

When I was driving home at around 4pm, I drove pass Ploenchit intersection and spotted a crowd in front of Wave Place building at the corner of the street. My first guess was it might be another bomb threat but then when I turned and drove along Petchburi Road, I saw the same scene in front of Electrolux Building. I suspect something happened and tuned in Jor Sor 100 radio station and found out it was an earthquake. However, I didn't feel anything while driving.

Our first citizen reporter, Joel Barlow, writes to us about his experience of the quake.

It started slowly - I was reading while laying on my bed and it shook. Then it became violent and a roof extension between our house and car-port fell down. A picture continued swaying several minutes... For a second or two it was very scary, and the whole thing seemed to last more than just a few seconds, quite long enough to really wonder what was happening, and know, but not long enough to go stand in a doorway or anything.

Tai, an office worker at Order House Building, Ratchadapisek Road, called The Nation and reported the following with a shaking voice:

"Shortly before 4pm, while I was sitting at my office on the 10th floor, I felt the building sway twice and the curtain moved like it was being blown by the wind.

Somebody shouted, 'Earthquake!" We all ran out of the building using the stairs, not the elevator. We waited downstairs for some 30 minutes and went back to work as if nothing had happened."

An office worker at the 23-story Olympia Building on Ratchadapisek Road reported that she felt uncomfortable with a swaying motion.

"Before the earthquake I took some medicine to kill my headache. At first I thought it was side effect of the medicine as I saw the curtains swaying for about a minute.

"I called the supervisors in charge of the building to check what had happened. When they mentioned the earthquake, I logged in the website of Geological Department to check."

Neelanut Noothong, an office worker on the 17th floor of the Shin Building III, reported:

"At first, around 4.10pm, I did not imagine an earthquake but I felt giddy. Then somebody said it was a quake and told us to go home. Many people panicked, running out of the building using the stairs, not the elevator. We stayed downstairs for about 20 minutes. After seeing that nothing had happened, we went back to work.  But later, the company allowed us to go home for safety reasons.

"I felt dizzy for a few minutes. Other staff felt the same and we realised it was an earthquake. I rushed to pick up my belongings before joining the others and running down from the building. When we reached the ground, many people from nearby buildings were already there. We were told to go home."

Tidarat Israngkul na Ayudhya works on the 33rd floor of U Chuliang Building:

"At about 4.25pm, the curtains started shaking at the windows and I felt dizzy as if I were sitting in a boat. So did my other colleagues. We heard no alarm but we felt the danger so decided to leave the office.

Once we arrived at the fire escape, almost everyone was already there. Although the maid insisted the alarm was on and people were evacuated from the building, no one in our office heard it.

After 20 minutes in the fire escape, we managed to come to Lumpini Park where other thousands of office workers are, like the drill told us to.

Chutima Thawornrojpatana works on 21st floor of Sinthorn Thani on Wireless Road:

"I didn't feel a thing but all my colleagues felt the shake and felt dizzy. No alarm was on but everyone agreed to leave the office. After some 10 minutes, we arrived the ground floor and still didn't know what to do or where to go."
