Solutions marked as [A], i.e. ‘automatic’, are PRELIMINARY AUTOMATIC locations. They are derived by an AutoLocation procedure using all available automatic picks from the stations received in real time at NOA, including the following networks: NOA(HL), AUTH(HT), UPSL(HP), NKUA(HA), ITSAK (HI), HMU (HC), GSD(CQ), GEOFON(GE), MEDNET(MN), INGV(IV), RESIF(CL) and KOERI(KO). They are updated automatically as new data streams in.

 

Type [A] solutions have not been revised by a seismologist and could contain information of uncertain quality. NOA does not provide any guarantee for this information and the risk derived from improper use is assumed exclusively by the user.
When type [A] solutions are revised by a NOA seismologist, then they are then marked as [M], i.e., ‘manual’. Solutions marked as [M] may be improved at a later time without notice.

 

All magnitudes reported on this page are LOCAL magnitudes (ML), computed based on synthetic Wood-Anderson waveforms. For larger events, ML estimates may differ from other magnitude scales, most notably MOMENT magnitudes (Mw). For Mw estimates for selected events, please refer to our dedicated moment tensor page. For more detailed information on the stations used, please visit the webpage of the NOA HL Seismological Network.

Call for students to participate to the Corinth Rift Laboratory School 2021
In the wider region of the Corinthian Gulf, a concerted effort is taking place for more than 30 years, for the advancement of understanding of geophysical processes (e.g. earthquakes, landslides, tsunamis). Over time, extensional deformation rates of up to 15 millimeters per year are observed, between the North and South coast of the Corinthian Gulf, a phenomenon unique in Europe and worldwide for areas beyond tectonic boundaries...
