Unpacking the Science Behind Myanmar’s 7.7 Magnitude Earthquake

Fast Summary

• A massive magnitude 7.7 earthquake struck central Myanmar on March 28, 2025, near Mandalay, causing important destruction and loss of life.
• The quake was followed by a magnitude 6.7 aftershock and nine smaller quakes ranging from magnitudes 4.4 to 4.9 in the same region that day.
• At least 144 people have died, wiht 732 injured, according to Myanmar’s military junta; a monastery and other buildings were destroyed in Mandalay.
• In Bangkok, Thailand (over 700 km from the epicenter), at least 10 deaths occurred when a construction site collapsed; 16 people were injured and over 101 are missing due to structural failures attributed to the tremors.
• Experts attribute the seismic activity to the Sagaing Fault-one of Earth’s major strike-slip faults-which spans almost 1,000 miles through Myanmar toward the Andaman Sea.
• Scientists commented on similarities with earthquakes caused by faults like california’s san Andreas Fault or those resulting from tectonic collisions along convergent boundaries such as India’s impact on Eurasia forming the Himalayas.

Indian opinion analysis

This devastating earthquake underscores Southeast Asia’s vulnerability due to its location within tectonically active zones produced by plate movements involving india’s collision with Eurasia millions of years ago-a process that continues today. Straddling key fault lines like Sagaing increases regional susceptibility not only for countries like Myanmar but also for neighboring nations, including india’s northeast vulnerable regions (even though this specific quake did not trigger direct damage in India).

The humanitarian loss reflects urban vulnerabilities stemming from insufficient disaster-resilient infrastructure across Asian nations situated near seismically active plates-a shared challenge between India’s cities and those affected here (e.g., Bangkok or mandalay).

From an Indian perspective: This event serves as a reminder of similar risks faced domestically along Himalayan fault systems or zones surrounding significant population centers where preparedness priorities remain critical amid growing urban density.
