The Nellore district in the Southeastern part of Andhra Pradesh is one of the nine coastal districts of the state. The microtremor activity in the district started in October 2015 and continued up to July 2016. During this period, a few hundred tremors were recorded by the temporary seismic network installed locally by the CSIR-NGRI. Apart from the data recorded by this network, those from the semipermanent seismic stations at Racherla, Addanki, Cuddapah, Srikalahasti and Srisailam were used in the study1.Full Text

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.Full Text
