Seismicity of Mosul Dam Reservoir for the Monitoring Year 1990

Seismic activity has been studied at Mosul dam reservoir for the period January to 20th July 1990. 33 micro-earthquakes of magnitude up to 3 ML were located. Nearly all earthquake epicenters were located within a radius of less than 25 km from the dam site. All the hypocenters, except one, were located at depth less than 2km from the lake s surface, which means there is no change occurred in the seismicity behavior from the previous monitoring period March 1986 to end of December 1987.
