| Zusammenfassung |
| The Lorca earthquake of 11 May 2011 in the Betic Cordillera of SE Spain
occurred almost exactly on the Alhama de Murcia fault, a marked fault that
forms part of a NE-SW trending belt of faults and thrusts. The fault belt is
reminiscent of a strike-slip corridor, but recent structural studies have
provided clear evidence for reverse motions on these faults. Focal
mechanisms of the main earthquake, but also of a foreshock, are strikingly
consistent with structural observations on the Alhama de Murcia fault. This
strengthens the conclusion that, rather than a strike-slip fault, the fault
is at present a contractional fault with an oblique reverse sense of motion,
presumably in response to the NW-directed motion of Africa with respect to
Europe. |
