Myanmar Quake Severity Explained by Scientists, Greater Seismic Risks Forecasted
Massive 7.7 Earthquake Strikes Myanmar and Thailand, Thousands Feared Dead
A devastating 7.7 magnitude earthquake struck near Mandalay, Myanmar, on Friday, with tremors felt across Thailand and as far as China’s Yunnan province. The U.S. Geological Survey (USGS) warns casualties could range between 10,000 and 100,000. A second 6.4 magnitude quake hit just 12 minutes later, exacerbating the crisis.

Why Was the Earthquake So Destructive?
The quake originated along the Sagaing Fault, a 745-mile tectonic boundary where the Indian and Sunda plates grind past each other at 49mm per year. When these plates “stick,” energy builds up and releases violently as a slip-strike earthquake. The shallow depth of 6.2 miles (10km) amplified destruction, channeling more force into buildings.

Scientists had warned of this risk. In January, researchers noted the Sagaing Fault’s middle section was “locked,” storing dangerous energy. “This disaster was predictable,” said Prof. Bill McGuire, a geophysical hazards expert. “The shallow depth and urban proximity maximized damage.”
Aftershocks and Ongoing Risks
Aftershocks pose severe threats, destabilizing already damaged buildings. “Rescue teams face collapsing structures and further tremors,” McGuire added. The USGS predicts hundreds of aftershocks, some potentially exceeding magnitude 6.

Poor Infrastructure Worsened the Toll
Myanmar’s rapid, unregulated urbanization and Thailand’s high-rise vulnerabilities led to catastrophic collapses. Videos showed buildings crumbling in Bangkok, including a high-rise under construction. “Earthquakes don’t kill people; collapsing infrastructure does,” emphasized Prof. Ilan Kelman, criticizing lax building codes.

Historic Context and Recovery Challenges
Myanmar’s last major quake in 1956 predates modern seismic standards. Hospitals in Naypyidaw are overwhelmed, and rescue operations race against time. With the region embroiled in civil conflict, recovery efforts face immense hurdles.
As survivors grapple with loss, scientists stress the urgent need for earthquake-resistant infrastructure to prevent future tragedies. For now, the focus remains on saving lives amid relentless aftershocks.
