The 7.7 magnitude quake, with an epicenter near Mandalay, Myanmar's second largest city, struck at midday and was followed by a strong 6.4 magnitude aftershock.
The full extent of death, injury and destruction was not immediately clear — particularly in Myanmar, one of the world's poorest countries. It is embroiled in a civil war and information is tightly controlled.
The head of Myanmar’s military government said in the televised speech on Friday evening that at least 144 people were killed and 730 others were injured.
“The death toll and injuries are expected to rise,” Senior Gen. Min Aung Hlaing said.
Photos from the capital of Naypyidaw showed multiple buildings used to house civil servants destroyed by the quake, and rescue crews pulling victims from the rubble.
Myanmar's government said blood was in high demand in the hardest-hit areas. Images of buckled and cracked roads in Mandalay and damaged highways as well as the collapse of a bridge and dam raised further concerns about how rescuers would even reach some areas in a country already enduring a widespread humanitarian crisis.
Near Bangkok’s popular Chatuchak market, a 33-story building under construction, with a crane on top, crumpled into a cloud of dust, and onlookers could be seen screaming and running in a video posted on social media.
