(Thailand, 189 km NW of epicenter) : It was very similar to the one we had two days ago. It only lasted seconds. I stood with my hands on the wall and it ended quickly. Then I went on the line app to ask who else felt that. My fan was shaking and I could feel the wall kind of trembling. No sound that I could distinguish though. I emailed the Thaiger paper to see if we had had another earthquake. (reported through EMSC)
