Bangkok Declared Disaster Zone Following Powerful Myanmar Earthquake
It depends how the waves travel, the type of wave, and intensity each individual type, and direction of the movement. Body Waves (move through the inside of the Earth) P-Waves (Primary Waves), these are Fastest type of seismic wave and move in a push-pull (compressional) motion, like a slinky. These are the first to be detected by seismographs. S-Waves (Secondary Waves), Slower than P-waves, move in a side-to-side (shear) motion, perpendicular to the direction of wave travel. These cause more damage than P-waves because of their stronger movement. Surface Waves (move along the surface of the Earth) Love Waves, which move the ground side-to-side, like a snake, only travel along the surface. Usually cause a lot of damage to buildings. Rayleigh Waves, which move the ground in a rolling, elliptical motion (like ocean waves). Slowest of all seismic waves, and cause both up-and-down and side-to-side shaking. Depending upon how the quake occurred impacts the type of wave and even the direction of dissipation of energy. Thus: its possible the initial 7.7 Mw quake released a greater intensity of shear waves than the secondary 6.4 Mw aftershock. The magnitude of the 7.7Mw quake was estimated to be between 4-5 Mw in Bangkok (I've not seen any official figures) due to the dissipating of energy through the bed rock, which was then amplified by the 'basin effect' of Bangkoks 'bowl' lakebed setting.... effectively like shaking a bowl of jelly. Thus in layman's terms the quake in Bangkok was a 4-5 Mw Magnitude wobble, where as in area's such as Pattaya and throughout the Korat Plateau the energy of the all waves would have dissipated with no soft formations to amplify the energy. -

Big earthquake in CM just now!
Looks like the Superlai Monte opposite Decathlon is broken, 32 floors, biggest apt building in CM. https://thethaiger.com/news/national/chiang-mai-condo-closed-after-cracks-appear-post-myanmar-quake -

Thailand's Digital Card Chaos: Say Goodbye to TM6, Hello to Confusion!
This has zero value to anybody.......Things have worked just fine without the TM6....And things could continue to work just fine without this undated version of the pointless TM6.. -

Bangkok Shop Owner Defends Right to Sell Controversial Shirts
Years ago I was at my daughter’s school concert. I was the only farang and probably English speaker in the audience. A group of 8-9 year old girls took to the stage to perform a dance. The lead dancer wore a white T-shirt with the words “<deleted> off you w*nker” emblazoned across the front. The audience clapped appreciatively and were no doubt oblivious to the message. This shopkeeper should stand her ground . -

Nice One: I have not had an earthquake like this since NanTou in Taiwan.
While “impression” and “impressive” share the same root word (the Latin “imprimere” meaning “to press into”), the words have taken on different connotations in English. Using “impressive” to describe a tragic event can certainly come across as insensitive, even if the event left a deep impression on you.
