Indonesian Earthquake Travelled Faster Than Geological Speed Limit

Indonesian Earthquake Travelled Faster than Geological Speed Limit

Science

In September 2018, an earthquake with a magnitude of 7.5 on the Richter scale hit the Indonesia which had a massive impact. The quake ripped earth’s crust at very high speed and crossed the geological limit for the first time. The earthquake triggered the tsunami last year, and it took the lives of nearly 2000 people in Indonesia. The two teams of scientists have studied the data and concluded that the earthquake shattered the earth’s crust by traveling above the geological speed limit.

The earthquake’s center was a strike-slip fault, which is the line on which two tectonic plates are connected. When these two plates firmly override each other, the earthquake occurs.
Lingsen Meng, a seismologist at the University of California, said that the earthquake was way beyond the imagination and have immense power. The magnitude, speed, soil liquefaction, power, and everything was tremendous which caused the devastating effects and the tsunami in Indonesia. The earthquake lasted for nearly 35 seconds but roughly traveled nearly 150 kilometers within these 35 seconds.

The satellite imagery and the seismographic data showed these devastating images of the earthquake. After studying the data for nearly four months, teams of scientists are sure that the speed has crossed the geographic limits. The earthquake ruptures are the phenomenon in which the earth surface shatters due to the friction between tectonic plates. The speed is usually three kilometers per second, but this rupture traveled 4.218 kilometers per second breaking the limits. Most of the earthquakes do follow the geological speed limit. This is not the first time any breach has broken the speed limit as there are handful ones in the past that have achieved such moving speed.
