A 7.7 magnitude earthquake rattled much of Southeast Asia on Friday, flattening skyscrapers and leaving more than 1,000 people dead from Myanmar to Thailand.

B ANGKOK — The death toll from the massive earthquake that hit Myanmar nearly a week ago rose Thursday to 3,085 as search and rescue teams found more bodies, the military-led government said, and humanitarian aid groups scrambled to provide survivors medical care and shelter.

The human cost of last month's 7.7-magnitude earthquake that rocked Myanmar and Thailand is still rising more than a week later, with Myanmar state media revising the country's death toll up to 3,354 on Saturday.

As the road shook beneath him, Ko Zeyer sped past crumbled buildings, buckled roads and gaping sinkholes toward his hometown of Sagaing, the epicenter of the most powerful earthquake to hit Myanmar in a century.

Thousands were killed in 7.7 magnitude earthquake. Yet military generals were slow to agree to pause in civil war fighting, and continued airstrikes.

Conditions could get even tougher for the huge relief effort after weather officials warned unseasonal rain could threaten the areas hardest-hit by the quake, such as Mandalay, Sagaing and the capital Naypyidaw.
