Katrol Hill Fault (KHF)
Part of: Prelims and GS-I -Geography
Context: According to a recent study, major earthquake events in the last 30,000 years have resulted in spectacular changes in landscape of the Katrol Hill Fault (KHF) in the Kachchh region, Gujarat.
- Real-time monitoring of earthquakes since 2001 Bhuj earthquake indicate that most of the faults in the region are seismically active.
- Studies have estimated the length of surface rupture produced by three large magnitude earthquakes during the last ~30,000 years as nearly 21 km.
- It also shows that the KHF is a credible seismic source capable of generating surface rupture hazard in the Kachchh Basin.
- An earthquake is a natural event of shaking of the earth.
- It is caused due to release of energy, which generates waves that travel in all directions.
- The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.
Do you know?
- Seismicity in the Kachchh region is highly complex as it is characterized by multiple seismic sources in the form of several East-West trending fault lines.
- These fault lines release continuously accumulating tectonic stresses at intervals resulting in earthquakes.
