Santa Cruz Islands Aftershock

Very Strong earthquake (aftershock) at the Santa Cruz Islands

Last update: June 5, 2013 at 8:36 am by By

Update : The Focal Mechanism is Reverse Faulting = stress or accumulates pressure inside the plates. This is a subduction area were the Australian plate is subducting the Pacific plate at a speed of 10′s of mm/year. The hypocenter today (65 km depth) reflects that this is a subduction earthquake. The Santa Cruz Islands are however a complex faulting area with a lot of shallow transform faults criss-crossing the islands.

Update : People living in this area of the world are used (can someone be used of course ?) at very strong earthquakes. According to the USGS 8000 people will have felt a moderate MMI V shaking, noting special for the Santa Cruz Islands.

A late aftershock has reminded on the cruel earthquake and tsunami of last February 6 at the island of Nendo. Today’s earthquake was more to the south, but a link with the mainshock in February cannot be excluded.
