Learn what causes earthquakes, how plate movement creates shaking, and what precautions you must follow. Easy science guide for all.
The primary cause of earthquakes is the sudden release of energy stored in the Earth's crust due to the movement of tectonic plates. This geological process is important today, especially in regions like Bangladesh, because of the significant risk of a major seismic event and the urgent need for preparedness and awareness.
Main Causes of Earthquakes
The Earth's outer layer is made up of large pieces called tectonic plates, which constantly move atop a semi-fluid mantle. Most earthquakes occur at the boundaries where these plates interact.
Tectonic Plate Movement: This is the most common cause. Plates move away from, towards, or slide past each other. Due to friction, they often get stuck at their edges (fault lines). Pressure builds up over time, and when this stress overcomes the friction, the plates suddenly slip, releasing a massive amount of energy as seismic waves that shake the ground.
Volcanic Activity: The movement of magma beneath a volcano can fracture rock and cause tremors, often as a precursor to an eruption.
Human-Induced Seismicity: Activities such as hydraulic fracturing (fracking), wastewater injection, and the creation of large reservoirs can alter the stress on existing fault lines, occasionally triggering earthquakes.
Glacial Isostatic Adjustment: The melting of glaciers due to climate change can remove significant weight from the Earth's crust, causing it to rebound and trigger seismic events in previously glaciated areas.
Why This is Important Today (2025)
The study of earthquake causes is particularly relevant in 2025 due to several converging factors:
Elevated Risk in Vulnerable Regions: Following a magnitude 5.5 earthquake near Dhaka in November 2025, experts have intensified warnings about the high vulnerability of densely populated areas like the capital. Bangladesh sits on active fault lines where significant stress has accumulated, making a major future quake likely.
Urban Sprawl and Weak Infrastructure: Unplanned urbanization and non-compliance with building codes in many high-risk cities worldwide, including Dhaka, mean that even moderate earthquakes can cause significant casualties and damage.
Cascading Effects: Understanding the causes helps anticipate secondary disasters. Earthquakes can trigger landslides, soil liquefaction, and tsunamis, which pose additional threats amplified by climate-related vulnerabilities like rising sea levels.
Call for Preparedness: The recent tremors serve as a "stark reminder" that communities and governments must prioritize disaster preparedness, enforce building safety standards, and conduct regular public awareness drills to minimize loss of life.

How To Create Earthquakes Conversation:
Why earthquakes occur: There are many explanations behind the occurrence of earthquakes. The main reasons are the increase in pollution and increase in crime in Bangladesh. There are many reasons, one of which is differences between people. Everything that Allah Ta'ala creates in the world is for the welfare of humans and animals living among humans. Still, the reason for creating differences among people is that they forget the traditions given by Allah and they start following their own traditions.
