6.3 quake rattles Santa Cruz Islands: global seismic tension follows Alaskan earthquake

June 24, 2011 – A massive 6.3 earthquake struck near the Santa Cruz Islands in the Pacific just hours after a massive 7.2 earthquake struck near the Aleutian Islands near Alaska. The 6.3 magnitude quake struck at a depth of 62 km along the tectonic plate boundary. Just 3 days ago a 6.1 magnitude earthquake struck this same region at a depth of 13 km. No tsunamic warnings have been issued. The warning I issued days ago about the potential of an outbreak of seismic events has arrived and great seismic agitation is showing up now on the global grid of seismograms- indicating the turbulence is still upon us.

Double moderate earthquakes, a 5.1 and a 5.2, has also struck the Mid-Indian Ridge which extends along the Great Rift through East Africa where the Nabro volcano is currently erupting in Eritrea. The Indian and African tectonic plates are moving apart due to spreading at the Mid-Indian Ridge. A 5.0 earthquake also struck the Karmadec region.
