This document appears to be a presentation given at Feni University on earthquakes. It includes slides about the definition of an earthquake, causes of earthquakes such as tectonic plates and fault surfaces, the relationship between plate tectonics and volcanoes, earthquake clusters including foreshocks and aftershocks, tsunamis caused by earthquakes, how to earthquake-proof structures, the anatomy of an earthquake including the epicenter and types of waves, signs of earthquakes, examples of earthquake damage in Indonesia and Nepal, a brief history of earthquakes in Bangladesh, and sources of information on earthquakes. The presentation concludes by noting that earthquakes are a dangerous natural disaster.

3. Earthquake
An earthquake is the sudden
movement of the Earth's tectonic
plates, resulting in shaking of the
ground. This shaking can result in the
damage of various structures such as
buildings and further breakdown of the
Earth's surface.

7. EARTHQUAKE CLUSTERS
•Related to each other in terms of location and
time.
•Most earthquake clusters consist of small
tremors .
•Foreshock.
•Aftershock.

8. TSUNAMI

Trunk Road, Feni-

• A Chain of fast moving waves in
the Ocean caused by powerful
earthquakes is a very serious
challenge for people's safety and
for Earthquake Engineering . Those
waves can inundate coastal areas,
destroy houses and even swipe
away whole towns .
