Statistics index of data on 70,000 earthquakes is presented in form of statistics tables. They include time, magnitude, and province. Because of the convertible nature of earthquake index, it is possible to make appropriate changes after entering data.
Time:The time of earthquakes were between various times; 0-3, 3-6, 9-12, 13-15, 15-18, 18-21, 21-24. Number of earthquakes has been determined.
Magnitude:Based on presented scales, earthquakes of less than 4, 4-5, 5-6, 6-7, and more than 7 were studied. Number of earthquakes has been also determined. Waves passing through the internal part of the Earth are called internal waves. They can propagate in all directions. At the second stage, surface waves are recorded by seismometers. The movement direction of these waves is perpendicular to their propagation. They can pass through solid environments.
Province:Numbers of occurred earthquakes were verified and a percentage is allocated for each province of Iran.
