Scope

Rapid global earthquake information has recently become a major task of the GEOFON Program. E.g. GFZ is a key node of the European Mediterranean Seismological Centre (EMSC) and has the responsibility for rapid global earthquake alerts. It became also a leading force in earthquake monitoring for tsunami warning in the Mediterranean and the NE Atlantic as well as for the Indian Ocean.

The GEOFON earthquake alert system is

one of the fastest sources for earthquake information worldwide,

at first fully automatic (type A solutions), therefore errors may occur,

only later verified by GEOFON seismologists on an ad-hoc (non 24/7) basis (type M solutions)

based on a virtual seismic network (GEVN: GEOFON Extended Virtual Network, > 600 stations) composed from GEOFON real-time stations as well as from compatible stations from partner networks (in Europe mostly the VEBSN: Virtual European Broadband Seismic Network).

issuing alert emails and RSS feeds.

still in beta status.

Please note that magnitudes larger than 8 may be underestimated (due to saturation of magnitudes mb, ML, mB and Mwp above different levels ).

Global Seismic Monitor

Global Seismic Monitor Global seismicity located automatically using the virtual network. Epicenter data and a detailed location map are displayed for the last "BIG" or "XXL" event. There is also a large version suitable for display on a 1280x1024 screen, e.g. using the Opera browser in full-screen mode.

Alert classification criteria

Normal

all events which are located automatically by a sufficient number of stations (>=25) or manually revised events ,

BIG

all events with M >= 4.5 in Central Europe,

>= 5.0 in wider Europe/Mediterranean area and

>= 5.5 outside of Europe/Mediterranean area,
