Das tönt verheerend, da muss man mit dem Allerschlimmsten rechnen.

Hallo

Hier noch zwei interessante Karten. Zum einen die sogenannte Shakemap. Das ist eine makroseismische Karten (Intensitäten). Auf einer solchen Karten kann man recht schnell sehen, wo Verletzte / Schäden zu erwarten sind. Das USGS berechnet solche Karten kurz nach einem Ereignis, damit Rettungskräfte schneller und gezielter helfen können.

USGS Shakemaps

Und der Momenttensor gibt Aufschluss über den rupture mechanism. In diesem Fall Dip Slip.



Best Double Couple:Mo=1.2*10**20 (seismisches Moment)
NP1:Strike= 92 Dip=27 Slip= 87
NP2: 275 63 91
(die beiden potentiellen rupture faults; an einer dieser faults hat der Versatz stattgefunden).
