Shallow crustal structure of the Central Bohemian Pluton, Czech Republic, inferred from refraction measurements
2009
Abstract
Since 1998, a seismic network has been monitoring the underground gas storage located near the town of Příbram in the Central Bohemian Pluton, Czech Republic. In addition to many hundreds of induced seismic events, several weak earthquakes have also been recorded from the vicinity of the nearby Orlík water reservoir.
To improve location of both types of seismic events, shallow crustal structure of the region is studied in the present paper. Refraction measurements to distances of about 20 km were carried out using quarry blasts as seismic sources.
Smoothed P-wave travel times were interpreted using the Wiechert-Herglotz method, which yielded a 1-D velocity model of shallow crustal structure down to a depth of about 1.7 km
