Il Fatto Quotidiano: Terremoto nell’isola di Creta: scossa di magnitudo 5.8 a 15 km di profondità vicino a Lerapetra
Questa mattina un terremoto di magnitudo 5.8 ha colpito l’isola di Creta, in Grecia. Come riporta l’Ingv, Istituto nazionale di geofisica e vulcanologia, la prima scossa è stata registrata alle 6:18 di mattina (5:18 in Italia) vicino alla città costiera di Lerapetra. Al momento non si segnalano vittime o danni.
Il sisma si è verificato a una profondità di 15 chilometri, motivo per cui, essendo relativamente superficiale, è stato avvertito con maggiore intensità. Successivamente sono state registrate scosse di minore entità.
Solo un mese fa, a marzo, un altro terremoto di magnitudo 5.3 aveva colpito la Grecia nord-occidentale senza causare danni significativi.
Secondo uno studio pubblicato a novembre sulla rivista Scientific Data, nel Paese sono state registrate più di 2.000 tracce di faglie sismiche attive. L’arcipelago, meta turistica molto popolare, è stato colpito da numerose scosse sismiche nel 2025, tra cui un terremoto di magnitudo 5.3 nel giugno dello scorso anno, che ha danneggiato i monasteri sul Monte Athos.

Earthquake in the island of Crete: magnitude 5.8 quake at a depth of 15 km near Lerapetra
This morning, a magnitude 5.8 earthquake struck the island of Crete, in Greece. According to the Italian National Institute of Geophysics and Volcanology (INGV), the first tremor was recorded at 6:18 a.m. (5:18 a.m. in Italy) near the coastal town of Lerapetra. At this time, there are no reports of casualties or damage.
The earthquake occurred at a depth of 15 kilometers, which is why, being relatively shallow, it was felt with greater intensity. Subsequent smaller tremors were also recorded.
Just one month ago, in March, another earthquake of magnitude 5.3 struck northwestern Greece without causing significant damage.
According to a study published in November in the journal Scientific Data, more than 2,000 seismic fault traces have been recorded in the country. The archipelago, a very popular tourist destination, has been affected by numerous seismic shocks in 2025, including a magnitude 5.3 earthquake in June of last year, which damaged the monasteries on Mount Athos.

"As shown here, even typical volcanoes erupting magmas of intermediate composition, like those defining magmatic arcs all around our planet, can remain inactive for deceivingly long times (>100,000 years). This can be the case even when the mantle continues to melt and primary magmas are being recharged. This scenario would often lead to the classification of volcanoes as extinct, only to rekindle unexpectedly. Such a behavior is connected to the state of their subvolcanic magma reservoirs, which might require longer times to accumulate the volumes of magma needed for an eruption due to low injection rates (3). Alternatively, the reservoirs might saturate in gas and exsolve a substantial amount of volatiles that render them less reactive to recharge, hence lowering the eruption frequency (4–7). Last, subvolcanic systems might be approaching extinction, by cooling and slowly becoming less eruptible as the rate of deep magmatic recharge decreases to a level where the system cannot remain above the solidus (3, 8–11). Therefore, relating magma chamber evolution to the phases of quiescence is essential to understanding the life cycle of volcanoes and to predict how the magnitudes and frequencies of future eruptions might change. This is particularly challenging, since magma chamber processes are largely obscured from direct observation."
