Powerful M7.3 Earthquake Hits 83km W of Nikol’skoye, Russia — Tsunami Warning Issued

A very strong and shallow earthquake registered by the USGS as M7.3 hit the Komandorskiye Ostrova region at 17:01 UTC on Dec 20. The agency is reporting a depth of 16.6 km (5.9 miles). 

At least 12 aftershocks have been registered with magnitudes ranging from 4.3 to 5.6.

The epicentre was located 83km (51.6 miles) W of Nikol’skoye, Russia, 187.9 km (116.8 miles) SE of Ust’-Kamchatsk Staryy, Kamtsjatka, Russia and 2,153 km (1,337 miles) NE of Sapporo-shi, Japan.

There are about 600 people living within 100 km (62 miles).

Based on all available data, tsunami waves of up to 1 meter (3.3 feet) above the tide level are possible for some Russian coasts, PTWC said at 17:49 UTC — though were unlikely to cause any damage.

The region surrounding today’s earthquake is an active plate boundary and regularly experiences moderate to large earthquakes. Twenty-one other earthquakes of M6.5+ have occurred within 250 km (155 miles) of this event over the preceding century. Many of these occurred within the Kuril-Kamchatka subduction zone to the west of today’s earthquake.

The largest nearby historic event in the Alaska-Aleutian system was a M7.0 earthquake to the east of today’s event in August 1925. A M6.7 event occurred to the northeast of today’s earthquake in December 2003.


Seismic and Volcanic activity has been correlated to changes in our sun.

The recent global uptick in earthquakes and volcanic eruptions is likely attributed to the drop-off in solar activity, coronal holes, and the increase in Galactic Cosmic Rays penetrating silica-rich magma.
