Abstract

Spatial-temporal patterns of aftershocks of the 2001 Mw7.7 Bhuj earthquake during 2001-2008 reveal a northward spatial migration of seismic activity in the Kachchh seismic zone, which could be related with the loading stresses caused by the continued occurrences of aftershocks on the north Wagad fault (NWF), the causative fault of the 2001-mainshock. Aiming at explaining the observed northward migration of activity, we modelled the Coulomb failure stress change (DCFS) produced by the 2001-mainshock, the 2006 Mw5.6 Gedi fault (GF) and the 2007 Mw4.5 Allah bund fault (ABF) events on optimally oriented plane. A strong correlation between occurrences of earthquakes and regions of increased DCFS is obtained on the associated three faults i.e. NWF, ABF and GF. Predicted DCFS on the GF increased by 0.9 MPa at 3 km depth, where the 7^th March 2006 Mw5.6 event occurred, whereas predicted DCFS on the ABF increased by 0.07 MPa at 30 km depth, where the 15^th December 2007 Mw4.5 event occurred. Focal mechanism solutions of three events on the ABF have been estimated using the iterative inversion of broadband data from 5-10 stations, which are also constrained by the first P-motion data from 8-12 stations. These focal mechanism solutions for the ABF events reveal a dominant reverse movement with a strike-slip component along a preferred northwest or northeast dipping plane (∼50-70°). Focal mechanisms of the events on all the three fault zones reveal an N-S oriented P- axis or maximum principal stress in the region, which agrees with the prevailing N-S compression over the Indian plate. It is apparent that the northward migration of the static stress changes from the NWF, resulting from the occurrence 2001 Bhuj mainshock, might have caused the occurrence of the events on the GF and ABF during 2006-08.

Abstract

According to the Gutenberg–Richter law¹, at least one earthquake of magnitude greater than 7 occurs every month along the seismically active belts in the world. Earthquakes are the manifestation of fault slip at depths, thus, there is no direct method to measure or observe them. However, seismometers can record ground velocity or acceleration caused by the occurrence of an earthquake when a fault slip occurs at depth. Therefore, setting up a seismic network is inevitable to understand the physics of earthquake processes, thereby, mitigating earthquake hazard.

Abstract

The present study focuses on the recent earthquake activity in Palghar region, Maharashtra, India. Until 31 August 2019, a total of 4854 earthquakes have been located here, whose local magnitude (M_L) varied from 0.1 to 4.1. Majority of the earthquakes (~94%) were located in the depth range 4–16 km. The precise earthquake relocations reveal two clusters. The N–S trending cluster north of 20.04°N extends to a depth of 10 km, whereas the NE–SW trending cluster to the south of 20.04°N extends to 16 km depth. The shallow northern cluster is noticed to be sandwiched between two mapped mafic intrusions, whereas the deeper southern segment shows earthquakes clustering around the mafic intrusion. The modelled composite focal mechanism solutions for both the north and south clusters suggest normal faulting with a minor strike–slip component as the dominant deformation mode for the Palghar region. From relocated seismici-ty, we have detected a deeper seismically active zone (with M> 3) at 4–16 km depth, occupying a crustal volume of 1440 km 3 (i.e. 20 km (in N–S) ×6 km (in E– W) and 12 km (in depth)) that dips toward 20°S and 70°W. This could be attributed to the large crustal stresses induced by the mafic intrusive body below the region.

Abstract

Generalized inversion has been used to estimate the various source parameters using S-wave spectra of 17 local crustal earthquakes recorded at the Dhanbad broadband seismic station, Jharkhand, India. Source parameters of another nine local events were compiled from an earlier study for detailed analysis. It was found from the source parameters of 26 events, that the corner frequency lies between 4.56 and 8.62 Hz, seismic moment between 6.2E + 12 and 2.11E + 16 N-m, stress drop between 0.11 and 37.13 MPa, source radius between 144 and 291 m, source displacement between 0.24 and 229 cm, moment magnitude between 2.44 and 4.82, and seismic energy between 8.3E + 06 and 1.13E + 13 Joule. Various empirical relationships were established based on the results of these 26 events, and it was found that the stress drop, corner frequency, source radius and source displacement are inter-related. Analysis also showed that the source parameters were correlated for stress-drop intervals of Δσ > 3.0 MPa and Δσ < 3.0 MPa, and were interpreted to be caused by interrupted rupture propagation because of strain weakening of the rock masses. The mere correlation between focal depth and stress drop found in the present study apparently accounts for high heterogeneities present in the crust beneath the study area.
