Barely 16 minutes ago, a magnitude 4.8 earthquake struck near Lambarene, Moyen-Ogooué, Gabon. The tremor was recorded early in the morning on Tuesday April 27, 2021 at 1:40 a.m. local time, at a shallow depth of 10 km below the surface.
The event was classified by the German Geoscience Research Center (GFZ), the first seismological agency to report it.
Our monitoring service identified a second report from the European-Mediterranean Seismological Center (EMSC) which also listed the earthquake at a magnitude of 4.8.
Based on preliminary seismic data, the earthquake should not have caused significant damage, but was likely felt by many people to be slight vibrations in the epicenter area.
Weak tremors could have been felt in Lambarene (20,700 inhabitants), located 29 km from the epicenter, and in Fougamou (5,600 inhabitants) at 51 km.
Other towns close to the epicenter where the earthquake could have been felt as very weak tremors include Ndjolé (5,100 residents), located 107 km from the epicenter.
