| Miêu tả: | The seismicity and the faulting in an area of 5000 km2 of the central part of Costa Rica between 9.5° - 10.3° latitude north and 83.5°-84.5° longitude west were studied. The faults were taken from recient geological maps of the area, and from the Geologic Map of Costa Rica (1:200,000) specially in areas where detailed studies have not been done. Earthquakes that ocurred between 1990-1994 were relocated with a tridimentional crustal model in order to find the best correlation between the epicenters and the faults. Focal mechanisms were done to characterize the types of fault. It was proved that there are two main faulting trends: northwest and northeast. The northwest one is considered the most importan because of the extention of the faults and the assciates seismicity. Three fault systems were found, one in the southern flank of the Cordillera Volcánica Central, another one in the northwestern flank of the Cordillera de Talamanca and the last one in the high lands of the Cordillera de Talamanca. Focal mechanisms suggest that mosth of the faulting is normal. |
