Description
We are hosting a colossal seismic activity of the Fentale-Dofen magmatic segment to date in the main Ethiopian rift starting from September 2024. This earthquake swarm is caused by a dike intrusion beneath Fentale volcano and laterally migrating north toward Dofen volcano with a total lengt of over 40 km shown by both seismicity and InSAR data. Thousands of earthquakes with maximum magnitude of 5.8 Mw recorded the events felt in many towns in Ethiopia including the capital, Addis Ababa. Moderate damage is sustained around the epicenter area and over 40,000 people are displaced from their homes. As earthquake rupture was never felt before with such intensity and distance to many towns and the capital Addis Ababa, panic is high and this phenomenon is the talk of the town. The Fentale seismic and magmatic activity provide strong evidence for the Ethiopian local and federal governments and the public at large in the Metahara area which hosts the major trade route to the Djibouti port. Such intensive seismic activity in a well known place can be used as ground truth (GT5) events for estimating average travel time curve through the RSTT (Regional Seismic Travel Time) algorithms.
