Abstract
Extreme Events an Geophysical Mon © 2012. American 10.1029/2011GM About 200 km 300 km Kachchh region of Gujarat in western India is seismically one of the most active intraplate regions of the world. It has six major E-W trending faults of the failedMesozoic rift that are being reactivated by thrusting. Kachchh had earlier experienced earthquakes of M7.8 in 1819, M6.3 in 1845, and M6 in 1956 and a small number ofM < 6 earthquakes. After theM7.7 earthquake in 2001, besides the continuing high seismicity in the rupture zone of 20 km radius, several other faults within distances of 60 km from the rupture zone and even after 5–8 years of the Bhuj earthquake are activated with earthquakes of M4–5.7 and associated sequences. Moreover, the seismicity to theM3–5 level is triggered along small faults at 20 locations up to 200 km south in the Saurashtra region. The unusually high seismicity along several faults is inferred to be triggered because of a stress pulse migration by viscoelastic processes after a 20 MPa stress drop due to the 2001 Bhuj earthquake.
