Venezuela, Caracas: 1967-2024

Summary

The Caracas cluster is named for the capital city of Venezuela. It contains the 6.5 Ms earthquake near Caracas on July 30, 1967 as well as a 6.0 Ms event on June 12, 1974 and a 6.1 Ms event on September 19, 1997. Much of the seismicity is near the Caribbean shore or offshore, so azimuthal control is weak, especially in the north. The problem is alleviated by including events over a wider than usual distance in longitude, about 430 km. This approach degrades the location calibration somewhat but the calibration level is still surprisingly good, about 1 km. All events have depth control fron near- or local-distance readings, teleseismic depth phases and/or waveform modeling. The dataset contains many teleseismic readings. [...]
