Historic Discovery: Watch Scientists Capture Earth’s Fracture During Burma’s Most Devastating Earthquake

On March 28, 2025, a strong earthquake hit Myanmar with a magnitude of 7.7, resulting in over 4,900 lives lost. The quake’s epicenter was near Mandalay and its tremors were felt as far away as Bangkok, Thailand. It originated along the Sagaing Fault, known for its horizontal movement between the Burma Microplate and the Sunda Plate.

Scientists described the event as a rare chance to see tectonic activity in action. A striking video from near Thazi displayed the ground shifting dramatically as the fault moved. According to the U.S. Geological Survey, a fault is a break in the earth between two rock blocks. This event marked one of the clearest recordings of such a fault slip.

The rupture extended over 460 kilometers, primarily at a depth of 10 kilometers. It released a massive amount of energy, shaking the ground intensely—rated as intensity IX on the Modified Mercalli scale. Notably, the largest surface displacement was recorded at 4.3 meters between Sagaing and Amarapura, affecting towns like Singu and Oktwin.

Experts noted that the earthquake exhibited a phenomenon known as “supershear.” This means the rupture spread faster than seismic shear waves, intensifying the quake’s impact. Research shared in ScienceDirect highlighted how this quick rupture increased the destructive energy, causing severe damage across populated areas.

The event lasted about 80 seconds, with its most intense shaking occurring roughly 30 seconds after it started. Understanding the mechanics of this quake provides valuable lessons for preparedness in future seismic events.

Scientists believe the observations from this earthquake can enhance models of fault behavior, offering new insights into earthquake risks. This knowledge will be crucial for improving safety strategies in areas prone to such events.

With earthquakes showing a growing trend, especially in regions along active fault lines, it’s essential to study these events to better protect communities in the future.
