Weekly Geophysical: 21 February 2014


Summary of report week: USGS is listing 25 events, EMSC is listing 27 events and GFZ Potsdam is listing 18 events. You can view each of these listings below. There was 1 active category force storm during the week of the report. Max 6 actively erupting volcanoes on any one day out of 7 during the week, over and above the 17 always erupting.
Using converted magnitudes (mb to Mw etc) USGS converts to 58 events and EMSC converts to 56 events. Potsdam events cannot normally be converted as the scale is not always known.

Volcanoes

Volcano information gathered from various sources, including the Smithsonian Weekly Volcanic Activity Report from which confirmation of reports is taken. A volcano is only included in the listing if there is significant ash above 1km height (white/steam clouds are not counted) or there is a significant lava flow. Crater incandescence, unless accompanied by the either of the preceding does qualify as an eruption.
