| The sensitive earthquake with М=5.2 has happened on February 27, 2008 at 0:56 GMT (03:56 Moscow time) in England, United Kingdom. |
| Parameters of the earthquake
have been determined in the Alert Service (AS) of Information
Processing Center (IPC) of Geophysical Survey of RAS in Obninsk with station data
obtained from digital and analog seismic stations of Russia, countries of CIS
and from abroad. Alert message on this earthquake has been delivered in 1 ÷ 5 min after
registration to the Ministry of Emergency of the Russian Federation (EMERCOM). |
| Preliminary processing has been done with data from 25 stations, accurate processing - with data 32 stations. |

| Historical records |
| In accordance with British Geological Service the earthquakes of such strength happened at the "base land part" of United Kingdom once per 30 years, and they are more typical for the adjacent regions. This earthquake is the strongest after the earthquake 1984 with ML=5.4, which occurred near Lain Peninsula and was felt on the vast territories of England and Wales. Within the whole historical and instrumental period of seismological survey the closest event (approximately 25 km to the north-east) to the earthquake reported here has happened on December 1703 with ML=4.2. |
