The two earthquakes which struck Venezuela on 24/6/26 were unusual for being so close together in time at this scale: a Magnitude 7.2 event was followed only 39 seconds later by a Magnitude 7.5 event. But, it is likely that the first earthquake ruptured one fault segment and transferred stress on to another fault which failed in turn, causing the second earthquake.

The events seem to have taken place on the tectonic plate boundary between South America and the Caribbean. The plates are moving past each other, laterally, in this region - similar to the San Andreas Fault in California.

The epicentres appear to be ~100 miles west of Caracas; whatever the casualties, earthquakes nearer would have been more destructive.

There is a risk of further earthquakes (aftershocks) in the Caracas region: the Venezuelan capital is in an earthquake-prone area, and local faults may have been loaded by the 24/6/26 events
