- We have collected the original documents with information for the Montesa earthquake.
- We have evaluated intensity values for 76 places.
- We have carried out a detailed study of damages for Montesa and Játiva sites.
- We have derived the PGA values form intensity distribution.
- We propose a bilateral rupture source model of 10Â km length.
The Montesa earthquake of 23 March 1748 in southeast Spain caused heavy damage and was felt over a wide area. It occurred in a region considered of low seismic hazard where few large earthquakes have happened. The abundant contemporary documentation about the damage caused by the earthquake, especially to the castle of Montesa and the city of Játiva, allows a re-evaluation of the seismic intensity distribution giving a maximum intensity IÂ =Â IX (EMS-1998). The focal parameters are estimated as: origin time 6Â h 30Â m local time, epicentre 39.00Â°N 0.64Â°W, and magnitude 6. The spatial distribution of ground acceleration derived from intensity values is modelled on a very shallow bilateral rupture of 10Â km length with strike 60Â°, dip 45Â°, and rake 90Â°. This source orientation agrees with the faults present in the area.
