Hopes are fading for people trapped beneath rubble in Myanmar and Thailand with the passing of a crucial 72-hour rescue window after which survival rates fall sharply.

Myanmar, also known as Burma, is in the throes of a prolonged and bloody civil war, which is already responsible for a massive humanitarian crisis.

Myanmar is still in shock after magnitude 7.7 jolted the Southeast Asian nation on March 28. The death toll continues to mount as the lookout for victims continues beyond 100 hours. To provide some relief to the victims who have either faced irreparable losses or have survived the catastrophic quake.

The 7.7 magnitude quake hit Friday, with the epicenter near Myanmar’s second-largest city of Mandalay. It damaged the city’s airport, buckled roads and collapsed hundreds of buildings along a wide swath down the country’s center.

The head of Myanmar’s military government, Senior Gen. Min Aung Hlaing, told a forum for relief donations in Naypyitaw that 2,719 people have now been found dead, with 4,521 others injured and 441 missing, Myanmar’s state MRTV television reported.

Myanmar’s ruling military has declared a temporary ceasefire in the country’s civil war to facilitate relief efforts following a 7.7 magnitude earthquake that has killed more than 3,000 people.

The magnitude 7.7 quake Friday rocked an impoverished Southeast Asian nation already beleaguered by years of civil war.

The military government suggested the numbers could still rise, saying “detailed figures are still being collected.”

Aid groups in the worst-hit areas of Myanmar said there was an urgent need for shelter, food and water after an earthquake that killed more than 2,700 people.
