Earthquakes are a sudden disaster. That is why the seismograph is kept in a constant state in the geologist's lab. Whenever an earthquake occurs, its magnitude can be known.
An earthquake can last only two or four seconds. It is also important to know how to find its epicenter in such a short time. Earthquake of the ground
It starts from a single place in the petals and is called its center or epicenter. Three types of waves rise from this place and shake the earth. In it, waves called p-waves move directly towards the ground surface. The S-wave moves diagonally. The speed of these three waves is different.
The P-wave moves at the highest speed. Depending on the hardness of the ground, these waves can travel at speeds ranging from three to 12 kilometers per second. Seismographs can tell when both types of waves reach the surface. Scientists determine the epicenter to be as deep as the distance between the P and S waves in seconds. Is. This method was discovered in 1914 by a scientist named Luno Gutenberg.
