* On December 15 ,2019- Davao del Sur on Mindanao island in Philippines an earthquake is recorded with a magnitude of 6.8Mw.

* Plate Tectonics- It says that earth is a very active planet that contains many plates on its surface.This plates move,interact and changes shape of earths outer layers.The volcanoes eruption and earthquakes are caused due to the movement of plates( tectonic plates).

When plates occasionally collide,fuse & break the hot rocks from deep inside the earth rise causing volcanic eruption.The movements in the boundaries of a plate leads to earthquakes because as plates move past each other a pressure or stress builds up.Most of this activity occures at divergent,convergent and transform types of plate boundaries.

On December 15,2019 earthquake occurred in Mindanao is in between the plates of Sunda Plate and Philippine Sea Plate this are accommodated partly by Philippine Fault System and Cotabato Fault System.

Sunda Plate is a minor tectonic plate in eastern hemisphere on which majority of Southeast Asia is located and Philippine Sea Plate is a tectonic plate that is comprised oceanic lithosphere lies beneath Philippine sea.This Philippine plate is surrounded by convergent boundaries.

* The damages or casualties due to an earthquake can be avoided by -

1.Designi and constructing structures capable of withstanding strong ground motions.

2.By using Seismic expectancy maps.

3.By knowing the peak acceleration and velocity.

4.knowing shape of earth interior and surface.

5.By using Sesmological Tomography

Apart from all this the use of resistance structures and being active at that particular time of distruction is important to reduce damages.
