20,000 earthquakes between Santorini and Amorgos less than a month

The earth is constantly shocking in the sea zone between Santorini and Amorgos, And seismic activity captures unprecedented numbers.

According to the data Εκπα (National Ikapital University of Athens), with January 26 By February 15 more happened 20,000 earthquakes, which is an alarming sign that attracts the attention of scientists to the volcano Columpo.

750 earthquakes in one day – 5.1 on the Richter scale

February 15, more registered 750 earthquakes from which 36 They had a magnitude above 2.5 On the Richter scale. Although not a single earthquake was recorded above 4.0in the morning February 17 The strongest seismic wave of magnitude was recorded 5.1 In the southwest of Anidros.

Artificial intelligence revealed a huge amount of seismic fluctuations

Seismology Laboratory Εκπα I analyzed the data using machine learning algorithms, which allowed to identify even smaller fluctuations. According to experts, from 20,000 General records 17 400 They had a magnitude above 1.0while the rest were smaller, but indicated intensive seismic activity in the region.

Strengthening research on Santorini – what scientists are afraid of

Constant activity raises questions about the state of the underwater volcano Columpowhich remains active. In an attempt to track geological changes, scientists Εκπα And Απθ (Aristoteliev University of Soloniki) established a new geodetic receiver GPS/GNSS On the cape ColumpoBy strengthening the monitoring network in this area. In parallel, gravitational measurements are carried out on the Santorini to study changes in the gravitational field, which may indicate the movements of the magma.

Is this a harbinger of a stronger earthquake

Experts do not exclude the possibility of a stronger earthquake in the future, since such phenomena preceded significant seismic events in the Aegean Sea. IN 1956 year earthquake of magnitude 7.5 In Santorini, it occurred after an increase in seismic activity in the same area. Although there are no signs of a direct threat, scientists continue to carefully monitor the situation, warning that the volcano Columpo It remains an invisible threat under the surface of the sea.

In particular, from the beginning of seismic activity in the zone of Santorini-amorgos with January 26 By February 15, 2025 year laboratory of seismology (Ες) Εκπα discovered and recorded in total 20,000 earthquakes using strict criteria to ensure the quality of the results, of which more 17 400 had a magnitude M1.0.

February 15, more registered 750 earthquakes from which 36 had a magnitude M2.5and there was not a single earthquake of magnitude M4.0at the same time, the two strongest had a magnitude 3.9.

According to the daily analysis of seismic data (without the use of machine learning methods) of the seismology laboratory ΕκπαFebruary 16, registered 89 earthquakes from which one had a magnitude M≥4.0and not a single one with magnitude M4.5.

The strongest earthquake has occurred February 17 V 09:49:51 (local time) and had a magnitude 5.1. Seismic activity is limited mainly by the southwest of Anidros.

Installation of a new geodetic receiver

Scientific group of geophysics laboratories (Γιάννης αλε Didυλος – Professor, Βασίλης σακάς – Associate Professor, Δρ. Σπύρος δίλαλος – Researcher) Εκπα installed and put into operation February 16 new permanent satellite geodetic receiver GPS/GNSS (station Lubo) on the cape Columpo On Santorini.

The station was installed in the place where the constant seismological station operates (Hτ.cmbo) The geophysical department of the Faculty of Geological Απθ and in cooperation with the seismology laboratory Εκπα.

Members of the Laboratory of Geophysics Εκπα Gravitational measurements are also carried out at the selected points of the existing local gravimetric network on Santorini to study temporary changes in the gravitational field.
