Mild tremors were felt in some parts of SPSR Nellore districts on Saturday. Panic-stricken people ran out of their houses in and around Marripadi and Atmakur after household articles were mildly shaking changed their places in the wee hours. Cracks also developed in some buildings, according to eye witnesses.
The micro-tremor activity in the district has started in October 2015 with a few hundred ones recorded by the CSIR-NGRI since then. The Nellore Green Schist Belt (NSB) comprises several geological and geochemically distinct tracts of deformed volcano sedimentary successions, National Geophysical Research Institute sources said.
