Tista' taqra bil- Malti.
Large parts of Malta were woken up by a magnitude 4.5 earthquake that occurred last night, 30 September at 03:00 local time. This afternoon Newsbook.com.mt asked people in Valletta if they felt the earth tremor. The majority of the people who gave us their reaction said they did not feel anything.
In a statement, the Seismic Monitoring and Research Group, SMRG, at the University of Malta explained that the epicentre of the earthquake was offshore, 23km south of Birzebbugia.
The SMRG operates the Malta Seismic Network, an array of 8 seismic stations installed over the three islands of Malta, Gozo and Comino. The network relays data to the University computers in real-time.
Yesterday’s earthquake was recorded on all the stations, as well as on seismic stations in Sicily.
The SMRG received more than 650 felt reports on its website from all over Malta, with most respondents reporting shaking and a rumbling sound, together with rattling doors and windows.
Another earthquake of magnitude 3.3 from the same epicentral area was felt yesterday 29 September at 20:24 local time.
The SMRG explained how the earthquakes are probably located on a fault which borders the Malta graben, a deep channel in the seafloor running parallel to Malta’s southern coastline. In recent weeks, this area has been seismically active and a sequence of more than 12 similar earthquakes have been recorded by the SMRG from the same area. Last night’s event was strongly felt because it had the largest magnitude in the sequence.
