An earthquake measuring 4.1 on the Richter scale with a depth of 15 km was felt in Karachi last night.
Why do earthquakes happen and how many fault lines are there in Karachi?
In fact, the earth’s crust is made up of seven large plates, three of which are in Pakistan, one is Eurasian, the other is Indian and the third is the Arabian plate.
Underground, these plates move, and the earth begins to shake.
There are two active fault lines in Karachi, one in the east of the Korangi fault line and the other in the south of Khairthar, where mild to moderate earthquakes have been coming.
Amir Haider, director of the National Tsunami Center, said that according to the 100-year record of earthquakes, about 106 earthquakes have been recorded in two dynamic fault lines of Karachi, all of which were of moderate magnitude.
