INGV seismologists have published their report on the seismicity of the past year, highlighting a substantially stable trend compared to previous years.
15.759 earthquakes have been located in 2025 by the Operations Rooms of the National Institute of Geophysics and Volcanology (INGV).: on average just over 43 events per day (three fewer than in 2024), approximately one every 33 minutes.
The general trend remains stableSince 2019, in fact, the number of earthquakes localized in Italy has hovered between 16.000 and 17.000 annually, a decline compared to the two-year period 2016-2017, when central Italy was affected by the seismic sequence that began on August 24, 2016, with the Accumoli (RI) earthquake. This sequence still contributes significantly to the country's seismicity, albeit with a lower number of events and with average low magnitudes.
These and other data, together with insights and curiosities, are part of the “Special 2025” dedicated to annual seismicity just published by the INGV.
The strongest earthquake of 2025, of magnitude Mw 4.8, was located on March 14 off the coast of the province of FoggiaThis event is part of the active seismic sequence in the area north of the Gargano Promontory (Lake Lesina area).
Over the course of the year, just over 10% of the seismic events recorded by the INGV Operations Rooms in Rome, Naples, and Catania had a magnitude of 2.0 or greater. There were 21 events with a magnitude between 4.0 and 4.9, 16 of which were recorded on Italian soil or in the surrounding seas and the remaining 5 between Croatia and Albania. Unlike previous years, there were no earthquakes with a magnitude of 5.0 or greater.
In 2025, seismic sequences occurred, with low magnitude values, some of which had already been active in previous years. In particular, seismic activity continued in the Campi Flegrei area, where on March 13 and June 30 the two earthquakes with the highest magnitudes of the current bradyseismic crisis (Md 4.6).
There were also numerous seismic events located in the southern Tyrrhenian Sea: the strongest, of magnitude ML 4.7, were recorded on February 7th near the archipelago of Aeolian Islands and on August 26th off the coast of Egadi Islands. In October, a small sequence also affected the province of Avellino, with very widespread resentment from the population.
"The Institute's research infrastructures, first and foremost the National Seismic Network (RSN), allow our Operations Rooms to carry out seismic surveillance of our country on a daily basis.", explains Salvatore Stramondo, Director of the Earthquake Department of the INGV. It should be remembered that the data acquired by the RSN are an invaluable asset, shared with the entire scientific community, on which seismologists can build a constant advancement of scientific knowledge..
The seismicity of 2025 is collected in a interactive map available on the INGVterremoti BlogFor each event, it is possible to view the main parameters (magnitude, depth, epicentral area); for the strongest ones, shakemaps are also available, highlighting the earthquake's impact on the area.
More information is available in the Special published on the INGVterremoti Blog.

This map does not include the microearthquakes (M<1) located by the Vesuvius Observatory (INGV-OV) in the volcanic areas of Campania and by the Etna Observatory (INGV-OE) in the volcanic areas of Sicily. 
Figure 2: Graph of seismicity in Italy and surrounding areas from 2012 to 2025. The blue columns show all localized events, the red columns only those with magnitude M ≥ 2.0. The peak in 2016 and 2017 is linked to the Central Italy sequence, which began with the Accumoli earthquake of August 24, 2016. The number of localized events available on the terremoti.ingv.it portal may vary over the years following analysis and revision by seismological analysts of the INGV Italian Seismic Bulletin.
