Weekly Geophysical: 21 Dec 2012

This is the first of the weekly geophysical reports which will be published on a Saturday for the previous 7 days to the Friday inclusive. For this week the data will be based on USGS publications for earthquakes, but later I hope to add comparisons to EMSC.

Because of the time span I am omitting the lower magnitude earthquakes and only going with Mag 5+.

When I get time I will extend the remaining graphs (volcanoes and hurricanes) backwards so they cover a six month period and then stretch out to form a rolling year as we go forwards.

Earthquakes for w/e 21 Dec 2012

Full details of Mag 6+ earthquakes can be found here

2 Mag 5+ quakes have been upgraded during December, one during this report week which as been added below. The changes will be reflected on the charts in next week’s report.

PETROPAVLOVSK-KAMCHATSKY, Russia, Dec. 19 (UPI) — An eruption of a volcano in Russia’s Far Eastern Kamchatka Peninsula is expected to last for at least two more weeks, an expert says.

Gennady Karpov, deputy head of the Institute of Volcanology and Seismology under the Russian Academy of Sciences, said the Plosky Tolbachik volcano is in an ongoing eruption with consistent intensity.

The 10,100-foot volcano, one of several in a volcanic complex 210 miles from the regional capital of Petropavlovsk-Kamchatsky, first erupted on Nov. 27, its first activity in 36 years, RIA Novosti reported.


SVERT reported that a thermal anomaly was detected over Snow, a volcano of Chirpoi, during 11 and 13-15 December.
