We could well be witnessing a new Honshu-type (Fukushima) earthquake cluster, North of Japan, off the east coast of the Kamchatka Peninsula, Russia. This morning, 5 major quakes (mag 6 or higher) have been recorded with a large number of ongoing heavy aftershocks.

The biggest quake recorded was a magnitude 7.4 at a depth of 20km at around 11 am UTC this morning. 2 magnitude 6.7s, a magnitude 6.6 and a magnitude 6.0 have also been recorded, along with a plethora of large aftershocks. All the earthquakes have been shallow. As of yet, NOAA has not released a tsunami warning.

Just a couple of days earlier, a magnitude 7.3 earthquake was recorded 1300 miles east of Kamchatka along the same fault line off the coast of Alaska, see the map below.
