A 4.3-magnitude earthquake has struck northern Evia, extending a seismic sequence that has rattled the island for three consecutive days, left residents of Mantoudi and Limni sleeping outdoors overnight and prompted school closures — though national university entrance exams scheduled on the island will proceed in structurally vetted venues.
The Monday tremor, centred 9 kilometres southwest of Prokopi at a depth of 17 kilometres, followed five overnight minor quakes ranging from 2.8 to 3.5 magnitude.
The cluster began Sunday afternoon when a 4.8-magnitude tremor was followed minutes later by a 5.2-magnitude quake — the most powerful in the sequence — which collapsed an uninhabited building in the village of Dafnousa, fractured walls in homes and churches and triggered landslides that briefly blocked regional roads.
Civil Protection Minister Evangelos Tournas travelled to Evia to coordinate the response.
State engineering teams are due to begin structural inspections of local buildings Monday morning.
Fire departments and disaster rescue units remain on alert.
The earthquakes were felt as far as Athens, approximately 120 kilometres to the south. No injuries or casualties have been reported across the entire sequence.
