Consider the following statements regarding earthquakes:
1. The point of origin of earthquake is called epicenter.
2. The lines joining the places which were affected earthquake at the same point of time are called homoseismal lines.
3. The more earthquake prone areas are at the merging of tectonic plates.
Which of the statement(s) given above is/are correct?
1 and 2
2 and 3
1 and 3
1, 2 and 3
An earthquake is the shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth’s lithosphere that creates seismic waves.
Hypocenter (also known as the focus)-The location where the earthquake begins. The ground ruptures at this spot, then seismic waves radiate outward in all directions.
Epicenter- The point on the Earth’s surface located directly above the focus of an earthquake. The lines joining the regions of same seismic intensity are called as Isoseismal Lines.
The lines joining the places which experience the earthquake tremors at the same time called Homoseismal Lines.
Nearly 95% of all earthquakes take place along the tectonic plate boundaries, while few are intraplate earthquakes.
