A powerful 7.7 magnitude earthquake struck Myanmar on Friday, March 28, shaking large parts of the country and neighboring regions. The tremor, felt as far as India, Thailand, and Bangladesh, raised concerns about potential aftershocks and damage. As of April 1, 2025, the earthquake has resulted in over 2,700 confirmed fatalities and more than 4,500 injuries, with fears that the death toll could rise further. The epicenter was near Sagaing, close to Mandalay, Myanmar’s second-largest city. Rescue operations are ongoing, with hundreds still missing.
What Caused the Myanmar Earthquake?
Myanmar lies in a seismically active region where the Indian Plate collides with the Eurasian Plate. This tectonic collision generates immense pressure, which periodically releases as earthquakes.
The March 28 earthquake resulted from a strike-slip fault mechanism, where two tectonic plates slide horizontally past each other. In this case, stress had built up along the Sagaing Fault—one of Southeast Asia’s most active fault lines—and suddenly released, triggering the violent shaking.
Why Was It So Powerful?
Magnitude is measured using the Richter Scale and the Moment Magnitude Scale (Mw), which assess the total energy released. A magnitude 7.7 earthquake is classified as a major earthquake, capable of causing widespread damage, especially if it occurs in densely populated areas.
Several factors made this quake particularly strong:
- Depth: The earthquake had a shallow depth of around 70 km, meaning the seismic waves reached the surface with great intensity.
- Fault Type: Strike-slip faults tend to cause intense shaking over large areas.
- Location: Myanmar’s soft soil and urban structures amplified the tremors.
Impact on Myanmar and Neighboring Countries
The earthquake caused significant tremors across Myanmar and was felt in nearby countries, including India, Thailand, and Bangladesh.
Key Impacts:
- Buildings swayed and cracked in cities like Yangon and Mandalay.
- Panic and evacuations in high-rise buildings across the region.
- Thailand: A high-rise building under construction collapsed in Bangkok, killing at least 20 people and injuring 33 others, with dozens still missing.
- China: Structural damage and injuries were reported in Yunnan province.
- Healthcare Crisis: Myanmar’s hospitals are overwhelmed, with urgent needs for medical supplies and personnel.
- Rescue Efforts: International teams from China, India, and Russia have joined relief operations.
The Risk of Aftershocks and Future Earthquakes
After such a large earthquake, aftershocks frequently follow. These smaller quakes weaken already damaged structures and trigger landslides. Scientists closely track seismic activity to assess future risks and improve disaster preparedness.
How to Stay Safe During an Earthquake ?
For those in earthquake-prone regions, here are essential safety measures:
- Drop, Cover, and Hold On: Protect yourself from falling objects.
- Stay Indoors if Safe: Avoid windows, glass, and heavy furniture.
- If Outside, Move to an Open Area: Stay away from buildings, trees, and power lines.
- Prepare an Emergency Kit: Stock up on essentials like water, food, and first-aid supplies.
- Stay Informed: Follow local news and updates from seismological centers.
Final Thoughts
The 7.7 magnitude earthquake in Myanmar highlights nature’s immense power and the necessity of preparedness. With thousands affected, the urgency of rescue operations increases. International aid plays a crucial role, with organizations like Project HOPE actively delivering emergency medical care, water, and shelter. As the region rebuilds, efforts focus on relief operations, infrastructure recovery, and ensuring communities enhance their preparedness for future seismic events.
