Yeah quite strange that it effects here strong and looks like death toll gonna high here too. Huge construction collapse,80 construction workers missing.. from the video.. not many will survive and that's all happened in Bangkok
According to Google Maps "measure distance" tool it's ~630 miles, or ~1000 km. I am very surprised it was felt so strongly at such a distance.
Not surprising. A 7.7 is absolutely massive. (In terms of energy, 10^23.35 erg. Or 5 megatons of TNT, if my math works)
