The moving tectonic plates, in which the uppermost layer of
the earth is divided, not only collide at many places but also often slide past
each other. This causes friction and leads to problems once in a while. Stress
builds up, which then gets discharged very quickly. There is a jerk- the earth
trembles. This gives rise to shock waves that can cause a lot of damage at
places, depending on the intensity of the earthquake and where they occur.
Luckily, to some extent we can protect ourselves from these waves. Tsunami
occurs if the center of the earthquake lies below the sea.
Earthquakes occur mainly at the borders of the plates where
two plates slide past each other. Most earthquakes occur in the Himalayan
region. The actual seismic center, the ‘hypocenter’, lies deep below the
surface of the earth. The point on the surface of the earth lying immediately
above this is called the ‘epicenter’. Scientist can determine this point. They
measure the time it takes the shock waves to reach the seismic stations and
draw circles around the epicenter and two other seismic stations. The radius of
these circles corresponds to the measured time. The point of interaction is the
epicenter.
Hey guys this is aakash ghimire. I write things in my own way hence, if you get any confusion and complementation reguard this post, plz mention that into comment.
