Abstract

The Montesa (Valencia) earthquake of 23 March 1748 and the Orán (Algeria) earthquake of 9 October 1790 caused heavy damage and were felt over a wide area. The abundant contemporary documentation about the damage caused by these earthquakes, allows a re-evaluation of the seismic intensity distribution giving a maximum intensity I = IX (EMS-1998) for Montesa and IX-X for Oran. From intensities distribution it is possible to correlate the seismic ruptures with the geological faults in the epicentral area. For the Oran earthquake we propose an off-shore focus due to the occurrence of a tsunami. The Montesa and Oran earthquakes have occurred in a region considered of low seismic hazard where few large earthquakes have happened.
