A magnitude 1.9 microseism recorded in the Madeiran sea

dnoticias.pt12 September 2026 at 09:32

A magnitude 1.9 microseism was recorded this morning at the Josephine submarine mount, in the Atlantic, according to the Portuguese Institute of the Sea and the Atmosphere. The seismic event occurred at 02:59:57, UTC time, and had its epicentre located at coordinates 36.995 degrees North and 14.6 degrees West.

The earthquake occurred at a depth of 10 kilometres, according to information provided by IPMA. The institution identifies Mount Josephine as the reference for locating the phenomenon.

Josephine is part of the Madeira-Tore submarine elevation, a geological structure that extends between the island of Madeira and the Portuguese continental coast. This submarine elevation is a significant geological formation in the Atlantic region.

Why this matters

This microseism interests readers in the Madeira region because it documents seismic activity in a submarine geological structure directly linked to the island. Mount Josephine is part of the Madeira-Tore elevation, which extends between Madeira and the Portuguese coast, being relevant for those who live or navigate these waters to understand the seismic behaviour of the region, even when the tremors are of low magnitude.
