Twelve earthquakes were recorded over a three-hour window across several islands of the Azores, Correio da Manhã reported on Tuesday. The activity included a magnitude 5.2 tremor that was felt on São Miguel, according to Observador, which said there were no reports of personal injury or material damage.
Açoriano Oriental reported a quake of magnitude 5.3 that was felt on both São Miguel and Terceira, while O GLOBO described a magnitude 5.2 earthquake on the Portuguese island. The slight differences in reported magnitude reflect the separate readings carried by each outlet.
Observador reported that two earthquakes were felt on São Miguel, the stronger of them at magnitude 5.2. Separately, dnoticias.pt reported a second tremor on the same island with a magnitude of 3.4.
The accounts from the Portuguese news outlets agree on the broad picture: a cluster of tremors struck the archipelago within a short period, the strongest of them above magnitude 5, and authorities had not reported harm to people or property as of Tuesday evening. The Azores sit on active tectonic boundaries, and small earthquakes are a familiar feature of life there, though a series of this size in a single three-hour stretch is notable.
What to watch next: whether the region's seismic monitoring services register further tremors in the coming hours, and whether official assessments confirm the absence of damage.
