| Zusammenfassung |
| Stress interaction modelling is routinely used to explain the spatial relationships
between earthquakes and their aftershocks. On 28 October 2008 a M6.4 earthquake
occurred near the Pakistan-Afghanistan border killing several hundred and causing
widespread devastation. A second M6.4 event occurred 12 hours later 20km to the south
east.
By making some well supported assumptions concerning the source event and the
geometry of any likely triggered event it was possible to map those areas most likely to
experience further activity. Using Google earth, it would further have been possible to
identify particular settlements in the source area which were particularly at risk and to publish
their locations globally within about 3 hours of the first earthquake. Such actions could have
significantly focused the initial emergency response management. We argue for routine
prospective testing of such forecasts and dialogue between social and physical scientists and
emergency response professionals around the practical application of these techniques. |
