A 5.5 magnitude earthquake occurred in Mediterranean Sea, offshore Malta. The figure shows the Forecast-points (green triangle) in which the alert levels are estimated. The isochrones (concentric curves starting from the epicenter) represent the tsunami propagation times estimated in the rapid simulation. Today, 21.04.23, at 22:19 UTC, a 5.5 magnitude earthquake was located in the central Mediterranean Sea, off the Malta coast, at geographic coordinates (lat, lon) 35.41N 15.79E and a hypocentral depth of about 9 km.
The earthquake's magnitude and hypocentral location, based on the decision matrix used, activated the Tsunami Alert Center service, which at 22:24 UTC, sent an INFORMATION message to the Civil Protection Department and the Mediterranean countries subscribing CAT services.
