Context: Recently, Myanmar was struck by an earthquake of magnitude 7.7, causing significant devastation in the country.
What Caused the Earthquake in Myanmar?
Tectonic Plate Movements
- The Earth’s lithosphere is divided into tectonic plates, which have been moving for billions of years. Their interactions create earthquakes and other geological features.
- The earthquake in Myanmar occurred due to “strike-slip faulting“, which happens when two plates rub sideways against each other.
Sagaing Fault
- Sagaing Fault is a 1,200 km long fault line, that runs from north to south through Mandalay and Yangon.
- Areas along this line are one of the country’s most earthquake-prone areas.

Why Was This Earthquake So Powerful?
- Magnitude: 7, making it one of the strongest quakes worldwide in the last two years.
- Shallow Depth: 10 km, which means seismic energy did not dissipate much before reaching the surface, causing more damage.
- Fault Line: Located on the Sagaing Fault, which is highly active and capable of producing large earthquakes.
Casualties and Damage
- Tragically, more than 1,700 people have died, and many more are still missing.
- Devastating damage, including collapsed buildings and major infrastructure failures, has been incurred in Mandalay and the Sagaing Region.
- The effect was also felt in nearby areas; tremors even reached Bangkok, Thailand, causing fatalities and structural damage.
Rescue and Relief Efforts
- Rescues of Survivors: Teams have been putting in a lot of effort to rescue individuals buried beneath rubble, such as the incredible rescue of a woman in Mandalay who was hauled to safety after 60 hours.
- International Aid: Rescue teams and much-needed medical supplies have been sent in by countries like China and India.
- Challenges: Regrettably, a lack of funding, ongoing civil unrest, and damaged infrastructure are making these efforts extremely difficult.
