4.0 Magnitude Earthquake Strikes Bangladesh, Shallow Depth Raises Concern

• A 4.0 magnitude earthquake struck Bangladesh on Tuesday, February 11, according to the National Centre for Seismology (NCS).
• The earthquake occurred at a shallow depth of 10 km, increasing the potential for stronger ground shaking and damage.
• Shallow earthquakes are considered more dangerous due to seismic waves having less distance to travel to the surface.
• Bangladesh is situated at the meeting point of three tectonic plates (Indian-Eurasia-Burma) and has five major fault zones.
• Dhaka, one of the world's most densely populated cities, is identified as one of 20 cities most vulnerable to earthquakes globally.
