- Abstract:
- The rapid estimation of the worst-hit zone of the earthquake-afflicted area of a destructive earthquake will facilitate the governments' precise search and rescue and allocation of relief supplies.In this paper,we integrate the multi-source data of the worst-hit zone in the Yangbi MS6.4 earthquake-stricken area estimated according to the intensity attenuation model,the instrumental intensity,the aftershocks sequence,and the power-outage data of transmission towers,and rapidly determine the area and spatial distribution of the worst-hit zone of the Yangbi earthquake.Our method of multi-source data fusion integrates the physical parameters of the earthquake with the data of the power-outage transmission towers,and gives the area,distribution direction,and the coordinates of the center of the worst-hit zone.These results are in good agreement with the worst-hit zone decided by field investigation.
