Past earthquake and tsunami damages in Chile

 

We searched the earthquake catalog, gCatalog of Damaging Earthquakes in the Worldh, under the conditions gEvents caused Tsunamih and gCountry: Chileh to find 70 events between 1562 and 2007 (some uncertain events are excluded).

In Table 1, we show the list of the events chosen among them under the additional condition that the casualty is equal to or larger than 100. For events after 1994, we change this condition to the one that there existed a casualty. There are 6 events for which the casualties are or exceed 1,000 including the 1960 M9.5 event. For the 1960 event (M 9.5), the damages in Chile and Japan are presented separately.

gCatalog of Damaging Earthquakes in the Worldh was compiled by Prof. Tokuji Utsu and now are maintained and updated by the IISEE, BRI. Here, we show the list of earthquakes

 

Table 1: The events chosen from the earthquake catalog, gCatalog of Damaging Earthquakes in the Worldh, under the conditions gEvents caused Tsunamih, gCountry: Chileh, that the casualty is equal to or larger than 100 (for events after 1994, we change the third condition to the one that there existed a casualty).

For the events that occurred on July 30, 1995, June 23, 2001, and November 14, 2007, earthquake information such as focal mechanisms, aftershock distributions, and rupture process models are available at the another earthquake catalog, gIISEEfs CMTs, Aftershock Distributions, Fault planes, and Rupture processes for recent large earthquakes in the worldh (http://iisee.kenken.go.jp/eqcat/Top_page_en.htm. The search page: http://iisee.kenken.go.jp/eqcat/Top_page_en_s.htm, where the KML file for Google Earth is available). This catalog has been made and been updated by the IISEE, BRI. Figure 1 shows the focal mechanism, aftershock distribution, and rupture process model for the event on July 30, 1995. Figure 2 shows the focal mechanism and aftershock distribution for the event on June 23, 2001.
