New earthquake swarm in Campi Flegrei, Italy

An earthquake swarm began in the Campi Flegrei area of southern Italy at 07:58 LT (06:58 UTC) on January 13, 2025.

The Campi Flegrei volcanic area, located near Naples in southern Italy, experienced a seismic swarm starting at 06:58 UTC on January 13.

Italy’s National Institute of Geophysics and Volcanology (INGV) reported the strongest event in the sequence having a magnitude of 1.2 ± 0.3 with a total of 95 localized earthquakes recorded so far. The depths of earthquakes ranged between 0.2 km (0.1 miles) and 3.1 km (1.9 miles).

The main events included an earthquake at 12:31 UTC with a magnitude of 0.6 ± 0.3 recorded at a depth of 2.9 km (1.8 miles). Another event at 07:04 UTC had a magnitude of 0.4 ± 0.3 with a depth of 1.9 km (1.2 miles). At 07:03 UTC, an earthquake with a magnitude of 1.1 ± 0.3 occurred at a depth of 0.4 km (0.2 miles).

The largest event was at 06:58 UTC with a magnitude of 1.2 ± 0.3 at a depth of 2.1 km (1.3 miles). The nearest seismic station was just 0.5 km (0.3 miles) from the epicenter.

While such events are common in seismically active regions like Campi Flegrei, their shallow nature can lead to increased felt intensity, even at lower magnitudes.

The Campanian volcanoes, Vesuvius, Campi Flegrei, and the island of Ischia, represent the most monitored and studied volcanic areas in the world because of the risk associated with a possible resumption of volcanic activity.

The ongoing swarm adds to the long history of seismic activity in the Campi Flegrei which is a 13 km (8 miles) wide volcanic complex. It encompasses Naples and extends south into the Gulf of Pozzuoli.

Regio rond supervulkaan nabij Napels opgeschrikt door aardbevingen
Het gebied rond de Zuid-Italiaanse grootstad Napels is opgeschrikt door verschillende aardbevingen. De zwaarste beving werd geregistreerd met een magnitude van 3,1 op de schaal van Richter, volgens het Nationaal Instituut voor Geofysica en Vulkanologie (INGV) .

Het epicentrum van de schok, die zich voordeed rond 9 uur ‘s ochtends lokale tijd, lag in de zogenaamde Flegreïsche Velden, een deel van de caldera van een supervulkaan. Voorlopig zijn er geen gewonden of grote schade gemeld. Uit voorzorg hebben meerdere scholen wel de lessen onderbroken.

De Campi Flegrei, of Flegreïsche Velden, is een gebied met frequente vulkanische activiteiten en wordt al een tijdje geteisterd door kleine en iets zwaardere aardbevingen. Onderzoekers roepen al langer op voor extra voorzichtigheid vanwege deze aardbevingen. In de regio geldt al meer dan tien jaar code geel.

De supervulkaan
Supervulkanen onderscheiden zich door hun bijzonder grote magmakamer en enorme kracht: ze barsten daadwerkelijk uit, in tegenstelling tot gewone vulkanen.

In mei 2024 werd het gebied getroffen door de zwaarste aardbevingen van de afgelopen veertig jaar. De krachtigste beving uit die reeks had een kracht van 4,4 op de schaal van Richter. Na die schokken nam de regering in Rome nieuwe maatregelen en er kondigde ook plannen aan voor een mogelijke evacuatie van het gebied.

Earthquake swarm recorded in Campi Flegrei, Italy

An earthquake swarm began in the Campi Flegrei area of southern Italy at 08:03 LT (07:03 UTC) on February 5, 2025.

An earthquake swarm was detected at Campi Flegrei between 08:03 and 13:05 LT (07:03 and 12:05 UTC) on February 5, 2025. A total of 63 earthquakes were detected, with the highest magnitude event measured at 3.1 at a depth of 0.3 km (984 feet), according to the Italian National Institute of Geophysics and Volcanology (INGV).

The earthquakes are concentrated within the Campi Flegrei, a large volcanic area west of Naples. The events vary in depth with the shallowest recorded at 0.1 km (328 feet) and the deepest reaching 4.4 km (2.7 miles).

The total number of localized earthquakes in the Campi Flegrei region for the year 2025 has now reached 449

The Campi Flegrei area has been experiencing increased seismic activity in recent years, with scientists closely monitoring potential geophysical changes. Further analysis will determine if the swarm is linked to ongoing subsurface magmatic processes or tectonic adjustments within the caldera.

The Campanian volcanoes, Vesuvius, Campi Flegrei, and the island of Ischia, represent the most monitored and studied volcanic areas in the world because of the risk associated with a possible resumption of volcanic activity.

The ongoing swarm adds to the long history of seismic activity in the Campi Flegrei which is a 13 km (8 miles) wide volcanic complex. It encompasses Naples and extends south into the Gulf of Pozzuoli.

The region’s geology is marked by extensive ground deformation, fumarolic activity, and seismicity because of the underlying magmatic and hydrothermal systems.

Campi Flegrei has experienced cycles of uplift and subsidence since Roman times. Its earliest known volcanic products date back approximately 47 000 years.

The caldera was formed after two major explosive eruptions, the Campanian Ignimbrite eruption about 36 000 years ago and the Neapolitan Yellow Tuff (NYT) eruption around 15 000 years ago, which ejected over 40 km3 (9.6 mi3) of material.

After the NYT eruption, numerous smaller eruptions occurred from scattered vents both on land and underwater. Most activity was concentrated in three periods: 15 000 – 9 500 years ago, 8 600 – 8 200 years ago, and 4 800 – 3 800 years ago.

The most recent eruptions were recorded in 1158 CE at Solfatara and in 1538 CE (VEI 3) when the Monte Nuovo cinder cone was formed.

Over 200 earthquakes recorded during earthquake swarm in Campi Flegrei, Italy

An earthquake swarm began in the Campi Flegrei area of southern Italy at 16:53 LT (15:53 UTC) on February 15, 2025. The strongest in the series thus far was M3.9 on February 16.

A new earthquake swarm started at Campi Flegrei at 16:53 LT (15:53 UTC) on February 15. The area has recorded more than 203 earthquakes over the next 24 hours, with the strongest reaching M3.9 ± 0.3 on February 16, according to the Italian National Institute of Geophysics and Volcanology (INGV).

The earthquakes are concentrated in the caldera around Solfatara and Agnano.

The quakes are occurring at shallow depths between 0.2 km (0.12 miles) and 4.2 km (2.61 miles), a key characteristic of activity associated with ground deformation in Campi Flegrei.

Multiple earthquakes at varying depths were recorded on February 17, including M1.5 at 07:42 UTC, M2.7 at 07:14 UTC, M2.8 at 07:14:11 UTC, and M3.2 at 07:12 UTC.

Napels opnieuw getroffen door reeks lichte aardbevingen

Het gebied rond Napels, in het zuiden van Italië, is opgeschrikt door een reeks lichte aardbevingen. In de nacht van zondag op maandag had de krachtigste beving een magnitude van 3,9, zo meldt het Nationale Instituut voor

De zwaarste schok vond plaats rond 0.20 uur in de zogenaamde Flegreïsche Velden, een gebied met veel vulkanische activiteit enkele kilometers buiten het centrum van de stad. Het was de tweede beving met een magnitude van 3,9 die het gebied in minder dan 12 uur trof. In de afgelopen drie dagen werd het gebied minstens elf keer getroffen door bevingen met een kracht van 2 of hoger.

In eerste instantie waren er geen meldingen van schade of gewonden, maar scholen in de gemeente Pozzuoli zouden maandag uit voorzorg gesloten blijven, aldus burgemeester Gigi Manzoni volgens het Italiaanse persbureau Ansa. Ook in mei vorig jaar werd de regio tussen Napels en Pozzuoli getroffen door een tamelijk zware beving, met een kracht van 4,4, met het epicentrum in de Flegreïsche Velden.

De Campi Flegrei, of Flegreïsche Velden, is een gebied waar veel vulkanische activiteiten worden vastgesteld en dat sinds enige tijd wordt geteisterd door lichte maar ook iets zwaardere aardbevingen.

Over 550 earthquakes recorded at Campi Flegrei caldera, prompting school closures in Pozzuoli, Italy

An intense earthquake swarm is in progress in the Campi Flegrei volcanic caldera, southern Italy, since 15:53 UTC on February 15, 2025. More than 556 earthquakes with magnitudes up to M3.9 were registered by 13:00 UTC on February 18. As a precautionary measure, schools in the town of Pozzuoli, which is close to the epicenter of the earthquakes, are closed today.

An intense earthquake swarm started at Campi Flegrei volcanic caldera — also known as Phlegrean Fields — at 16:53 LT (15:53 UTC) on February 15, with the area recording more than 556 earthquakes by 13:00 UTC on February 18, according to data provided by the Italian National Institute of Geophysics and Volcanology (INGV).

The two strongest earthquakes measured M3.9. The first occurred in the Gulf of Pozzuoli at 15:30 LT (14:30 UTC) on February 16, and the second near Pozzuoli at 00:19 LT on February 17 (23:19 UTC on February 16).

In response to the increasing seismicity, Pozzuoli Mayor Gigi Manzoni ordered the closure of schools on February 18 to allow municipal technicians to conduct structural safety inspections.

The country’s Civil Protection Department also deployed volunteer emergency responders and established temporary shelters for displaced residents in Pozzuoli, Bacoli, and Naples.

Nello Musumeci, Civil Protection Minister, has appointed a special commissioner to oversee risk-prevention measures and has raised concerns over urban development in this seismically active region.

De Etna is weer actief, een van de ondergrondse in de buurt van Stromboli. Bij NPO en VRT een berichtje over het vulkanisme toerisme, en hoe lokale hulpverleners met lede ogen aanzien dat deze mensen slecht gekleed de ronkende Etna van dichtbij bekijken. Ze kunnen de toeristen niet tegenhouden, blijkbaar omdat ze ervan uit gaan toch wel gered te zullen worden.

Earthquake swarm and ground uplift at Campi Flegrei, Italy

Over 600 earthquakes were recorded at Campi Flegrei, Italy, between February 17 and 23, 2025, with the largest measuring M3.2. Around 1 cm (0.4 inches) of ground uplift was observed in the area of maximum deformation, coinciding with the onset of an earthquake swarm on February 15.

Seismic monitoring stations near the Campi Flegrei caldera registered a preliminary total of 692 earthquakes in a swarm that started at 15:53 UTC on February 15 and ended at 23:53 UTC on February 19. Two more swarms of much lower intensity (less than 30 events) were registered over the next 3 days.

According to the latest weekly bulletin from the National Institute of Geophysics and Volcanology (INGV), the strongest earthquake of this period reached M3.2, with most activity centered in the Solfatara-Pisciarelli sector.

Notably, between February 15 and 16, a localized uplift of about 1 cm (0.4 inches) was observed, coinciding with the onset of a seismic swarm. However, no significant uplift changes have been detected since February 16.

Since August 2024, the average uplift rate at the RITE GNSS station—located in the zone of greatest deformation—has been about 10 ± 3 mm (0.4 ± 0.12 inches) per month. INGV data indicate the total uplift at RITE has reached roughly 21 cm (8.3 inches) since January 2024.

Geochemical parameters did not show substantial variations during the reporting period of February 17 to 23. The temperature sensor near the Pisciarelli fumarole measured a weekly average of about 97°C (206 °F), aligning with previously observed trends in hydrothermal heating and gas emissions.

Earthquake swarm prompts state of emergency for Campi Flegrei, Italy

A state of emergency was declared for Italy’s Campi Flegrei area on May 13, 2025, following an M4.4 earthquake within a swarm of earthquakes that produced 49 registered events. The swarm began at 12:06 LT on May 13 and ended during the morning hours of May 14, according to the INGV Vesuvian Observatory. The Campi Flegrei caldera is one of Europe’s most closely monitored volcanic areas due to its dense population and history of significant unrest.

A state of emergency was declared for the Campi Flegrei area in southern Italy on May 13, following an M4.4 earthquake and a series of related seismic events.

The decision was announced by Civil Protection Minister Nello Musumeci with the goal of expediting ongoing risk mitigation procedures in response to the area’s increased seismicity attributed to bradyseism

“The persistence of the seismic swarm, which in two months has recorded three shocks clearly felt by the population, suggests the need to proceed with the declaration of a state of national emergency in the Campi Flegrei area,” Musumeci said.

The M4.4 earthquake occurred at 10:07 UTC (12:07 LT) near Pozzuoli, part of the Campi Flegrei caldera west of Naples. A subsequent M3.5 earthquake followed at 10:22 UTC.

The seismic events prompted evacuations of schools and public buildings, suspension of regional train services, and activation of emergency coordination centers.

According to the National Institute of Geophysics and Volcanology (INGV) Vesuvian Observatory, the seismic swarm began at 10:06 UTC on May 13 and consisted of 49 events with local magnitudes (Md) ranging from below 0.0 to a maximum of Md 4.4 ± 0.3. All earthquakes were located within the Campi Flegrei area.

The swarm ended during the morning hours of Wednesday, May 14.
