Myanmar Earthquake: A catastrophic 7.7-magnitude earthquake struck Myanmar on March 28, leaving a trail of destruction in its wake. The tremors were so severe that buildings collapsed in Myanmar and neighboring Thailand. Over 1,000 deaths have been officially confirmed, while experts fear the toll could cross 10,000 as rescue operations continue. But what made this earthquake so devastating? Let’s break down the science behind this natural disaster.
15 Earthquakes in 10 Hours: Why Myanmar Shook So Violently
According to the United States Geological Survey (USGS), Myanmar experienced a staggering 15 earthquakes in just 10 hours after the initial tremor. The first earthquake, which struck at 12:50 PM (local time), had a magnitude of 7.7 and an epicenter just 10 km deep near Sagaing city. The second major earthquake (6.4 magnitude) followed 12 minutes later, leading to further devastation.
Why Myanmar is Prone to Deadly Earthquakes
Myanmar is situated in one of the most seismically active regions in the world. It lies on the boundary between two major tectonic plates—the Indian Plate and the Eurasian Plate. This area, known as the Sagaing Fault, is a hotspot for earthquakes due to constant tectonic activity.
Renowned seismologist Joanna Fore Walker from University College London explains:
“The Indian Plate and Eurasian Plate move in opposite directions, one northward and the other southward. This creates friction, leading to ‘strike-slip’ earthquakes.”
These types of earthquakes occur when tectonic plates slide past each other horizontally. While they are generally less powerful than subduction zone earthquakes (where one plate moves beneath another), their shallow depth can make them extremely destructive.
Why Was This Earthquake So Devastating?
British geologist Roger Musson highlights the biggest factor that led to massive destruction: the depth of the earthquake.
“The epicenter was just 10 km deep, which means the seismic waves had little time to dissipate before hitting the surface. This amplified the shaking intensity, causing severe destruction.”
This explains why entire buildings collapsed within seconds and why the impact was felt as far as India, China, Thailand, and Bangladesh.
Massive Damage in Thailand
The earthquake’s shockwaves reached Bangkok, Thailand’s capital, where a 30-story under-construction building collapsed. Reports suggest 80 workers were trapped under the debris, with 10 confirmed dead. As a result, the Prime Minister of Thailand declared Bangkok an emergency zone to accelerate relief efforts.
Myanmar Declares Emergency: Global Aid Rushed In
The hardest-hit areas in Myanmar include Sagaing, Mandalay, Bago, and Shan. Given the unprecedented destruction, the Myanmar military has declared a state of emergency and appealed for international aid.
India Launches ‘Operation Brahma’
In response, India has sent 15 tonnes of relief material to Myanmar under ‘Operation Brahma’, aimed at providing immediate assistance to earthquake victims.
What’s Next? Is Another Earthquake Expected?
Scientists warn that aftershocks could continue for weeks or even months. Residents in Myanmar and Thailand should remain alert, as further tremors could strike without warning.
How to Stay Safe During an Earthquake
While earthquakes are unpredictable, following these safety measures can save lives:
- Drop, Cover, and Hold: Take cover under a sturdy object and hold on until the shaking stops.
- Stay Away from Windows and Heavy Objects: These can shatter or fall, causing severe injuries.
- If Outdoors, Move to an Open Space: Avoid buildings, bridges, and power lines.
- Prepare an Emergency Kit: Keep essentials like water, food, flashlight, and first aid supplies ready.
The Myanmar earthquake is a grim reminder of nature’s power. While relief efforts are underway, the long-term impact of this devastating event remains uncertain. Scientists continue to monitor the region for aftershocks, and global aid is pouring in to support the victims.
