"Water level fluctuations in twenty-one observation wells have been monitored for the last 10 years around the seismically active Koyna–Warna\nregion, western India where earthquakes continue to occur even after four decades of the initiation of the seismic activity in the region. Fourteen of\nthe observation wells act as volume strain meters as their water levels show earth tidal signals. Our analysis suggests three types of response of the\nwell water levels to seismo-tectonic effects, i) one to local earthquakes, ii) to regional and teleseismic events, and iii) to local fluctuations in rock\nstrain on regional scale. We observed five cases of co-seismic step-like well water level changes, of the order of few centimeters in amplitude,\nrelated to earthquakes in the magnitude range 4.3≤M≤5.2. All these earthquakes occurred within the network of wells drilled for the study and\nwithin 25 km distance of the recording wells. In three cases, drop in well levels preceded co-seismic step-like increases, which may be of\npremonitory nature. The second type of response is observed to be due to the passing of seismic waves from regional and teleseismic earthquakes\nlike the M 7.7 Bhuj event on January 26, 2001 and the M 9.3 December 26, 2004 Sumatra earthquake. The third type is a well level anomaly of\ncentimeter amplitude coherently occurring in several wells. The anomalies are similar in shape and last for several hours to days.\nFrom our studies we conclude that the wells in the network appear to respond to regional strain variations and transient changes due to distant\nearthquakes. The two factors which are important to co-seismic steps due to local earthquakes are the magnitude and epicentral distance. From the\nlimited number of events we found that all local earthquakes exceeding M≥4.3 have produced co-seismic changes. No such changes were\nobserved for earthquakes below this magnitude threshold."^^ . "2008" . . "456" . "1-2" . . "Elsevier"^^ . . . "Tectonophysics"^^ . . . "00401951" . . . . . . . . . . . . .
