Kasset Tak Posted November 21, 2019 Share Posted November 21, 2019 This quake at least got me out of bed this morning! I hit the snooze button and basically in the same moment my house started shaking, so it became a "OK, I'M UP NOW!" reaction... ???? Link to comment Share on other sites More sharing options...

webcrawler00 Posted November 21, 2019 Share Posted November 21, 2019 I'm in Bangkok. Had two shakes before 7am this morning (about 30 seconds apart). My bedroom door even swayed by about 2 to 3 cm. Was a very visible shake! Second quake was bigger than the first. I'm on the 25th floor. Link to comment Share on other sites More sharing options...

whaleboneman Posted November 21, 2019 Share Posted November 21, 2019 I’m in Mindanao and met an American who was just about to move in to a fourth floor apartment in a five floor building. Then we experienced a 6.1 quake. He went to the building where an engineer was doing an inspection and deemed the building safe. The American gentleman didn’t like the looks of the cracks he saw and tried to break the lease. He was told not to worry. The next day he returned and found his apartment was now on the second floor of a three floor building. He decided not to move in. Link to comment Share on other sites More sharing options...
Shiver Posted November 21, 2019 Share Posted November 21, 2019 Felt the 6:51am in Udon, but not the first one. Just a couple of seconds and just a bit of window rattle. Did make me wonder whether to leave the building, but thought I'd wait until something bigger was on its way. Nothing after that. Didn't think the north was considered an quake zone. Learn something every day. No damage that I'm aware of. Link to comment Share on other sites More sharing options...

If Bangkok was to experience a large quake, I think much of the city would be completely destroyed. The issue is not so much even the construction of the buildings but the fact that Bangkok rests on clay. A big earthquake is basically like shaking a jello mold, waves amplify like they would not on a more solid foundation. This is what made the Mexico city quake so nasty. https://www.nytimes.com/interactive/2017/09/22/world/americas/mexico-city-earthquake-lake-bed-geology.html Link to comment Share on other sites More sharing options...

Tom89 Posted November 21, 2019 Share Posted November 21, 2019 I'm in Phayao. I felt the first one, but not the second one. That said I've felt far stronger quakes in Tokyo. Link to comment Share on other sites More sharing options...

NoComment Posted November 21, 2019 Share Posted November 21, 2019 The fabulous Kingdom is not America, UK, Australia or anywhere else in the world. Thailand has its own rules and regulations and will continue to look after its millions of citizens without OP revealing what happens in their own countries. I think everyone should be grateful that no injuries, deaths or damage has been reported and everyone is safe and well. Link to comment Share on other sites More sharing options...

CM is of more concern as are, especially, hydroelectric dams in Laos. Link to comment Share on other sites More sharing options...
buick Posted November 21, 2019 Share Posted November 21, 2019 i read that the first 'foreshock' occurred at 11:49 pm on wednesday. but i'm pretty sure the first one was 11:49 am on wed. i was walking through benjasiri park (next to emporium/phrom phong BTS in bangkok) and nearly fell down. wasn't sure what was going on. i lived 20 yrs in los angeles and then 20 yrs in san francisco so i've felt alot of them.

Rookiescot Posted November 21, 2019 Share Posted November 21, 2019 Was up as usual at 0600hrs. Woke my daughter for school at 0620 hrs. Neither of us felt any earthquake and we are in Nong Khai. How people felt it in Bangkok is beyond me. Link to comment Share on other sites More sharing options...

tabarin Posted November 21, 2019 Share Posted November 21, 2019 7 hours ago, NCC1701A said: I wonder if the Thais have inspected the dams in the north yet? Or the hundreds of small bridges on the highways? A retired Canadian who did that for a living told me most buildings here are build with the support like tooth picks, they will knack easily. Any serious earthquake would bring most buildings down to the floor, small bridges collapse in the north all the time too. He said, if renting on a higher floor, at least get the corner unit near the stairways. Personally seen some new developments in CM, walls are super thin as well the pillars, no (sound) isolation but more scary is the strength (or lack of). Would never buy something like this, that is for sure. A slash hammer would most likely give me entrance to the neighbours within minutes. Link to comment Share on other sites More sharing options...

GreasyFingers Posted November 21, 2019 Share Posted November 21, 2019 I did not notice anything but the wife saw the screen door shake. She tried to tell me via Google translate but the translation was not even an English word. No real damage but we had the interior of the house painted about a year ago so no signs of cracks but there are now cracks between the walls and ceilings.

SuwadeeS Posted November 21, 2019 Share Posted November 21, 2019 Luckily it wasn't in Bangkok. Imagine all the bridges over the mainroads come down to the street. The infra structure would be down for how many month? Link to comment Share on other sites More sharing options...
plachon Posted November 21, 2019 Share Posted November 21, 2019 Got the Xayaburi dam, the Hongsa lignite power station, and the Chinese-built high speed rail line, much of it half-built on concrete viaducts all within about 80 kms of the epicentre. Any reports of structural damage coming out of Laos yet? The railway especially, would be vulnerable to this quake, I'd imagine. Tunnels being bored and so not yet secured for quakes - and doubtful if they've factored in quake risk in any case. Link to comment Share on other sites More sharing options...

I assume that is always part of the equation when building?? I found a report about an earthquake in Chiang Mai in 2014. It says there was a ministerial regulation issued in 2007 which said that any building over 15m tall must be built to resist earthquakes of up to 7 on the Richter scale. Obviously this regulation does not apply to buildings constructed before 2007 and as for enforcement of the regulation well, your guess is as good as mine.

GroveHillWanderer Posted November 21, 2019 Share Posted November 21, 2019 3 hours ago, TheGhostWithin said: With each 0.1 increase in the Richter scale reading, the physical feeling is magnified - it is not a steady climb in the feeling of the quake. That's a little vague - to be accurate, since the Richter scale is logarithmic, each single digit increase on the scale represents a tenfold increase in measured amplitude. However even that tends to understate the effect in everyday language. In terms of energy, each single digit increase on the scale corresponds to an increase of about 31.6 times in the amount of energy released. What this means in turn, is that each increase of 0.2 on the scale leads to roughly a doubling of the energy released. Link to comment Share on other sites More sharing options...
