The deterministic behaviour of earthquake rupture beginning - Communications Earth & Environment An analysis of global earthquake catalogs suggests systematic differences exist in the earliest ground displacements between small and large events, which indicates that earthquake magnitude may be pr...

Can we tell how big an earthquake will get from its first seconds? Our new paper in
@commsearth.nature.com shows that early seismic signals already reveal the rupture’s fate — a step forward for earthquake early warning!

Earthquake rupture velocity and stress drop interaction in the Campi Flegrei volcanic caldera - Communications Earth & Environment Earthquakes at Italy’s Campi Flegrei caldera show unusually low seismic radiation efficiency, with most energy dissipated through off-fault damage and frictional processes, according to a time-domain-...

New insights on #CampiFlegrei earthquakes 🧠
Our paper in @commsearth.nature.com shows that <10% of released energy radiates as seismic waves — the rest is dissipated as heat and rock damage, acting as a natural cap on magnitude.

🚨 New in Nature Scientific Reports! We compare two #Earthquake Early Warning methods:
⚡ PLUM = high accuracy, short lead-times
⚡ QuakeUp = earlier alerts (up to 12s), but less stable at first
👉 Complementary tools for safer communities 🌍

Campi Flegrei, il vulcano sotto la città: tra segnali di vita e gestione dei rischi La caldera dei Campi Flegrei, nel sud Italia, è uno dei sistemi vulcanici più affascinanti e complessi al mondo. Situata nell’area metropolitana di Napoli, luogo naturalisticamente meraviglioso, è urb...

Non è così. L'energia si calcola a partire dalla magnitudo momento, che per il terremoto dei Campi Flegrei è circa 4. Quindi il terremoto del Myanmar è stato circa 355000 volte più energetico di quello max ai Campi Flegrei.

Potenza Earthquake (18/3/2025) The 2025 Potenza Earthquake

On Mar 18, 2025, a Mw4.0 quake near Potenza showed normal faulting. ~2.2 MPa stress drop, MMI VI (~4.9%g) near epicenter, complex extension. Early-warning worked in seconds. Innovative monitoring (DAS, apps) boosted real-time resilience.

Today’s Md 3.9 earthquake at Campi Flegrei showed how rupture directivity can shape ground shaking patterns. Data reveal a WSW increase in PGV, pointing to eastward rupture propagation. Insights like this help us understand seismic behavior in volcanic settings. Data: INGV & DPC networks.

Strong ground shaking at Campi Flegrei this morning, caused by the Md 3.1 earthquake of 07:52. Peak acceleration of 27 %g at the epicenter, near Solfatara crater, 3 %g at Bagnoli, where I live, few km apart.

An ancient, 60-km-long fault in southern Italy is repeatedly reactivated, weakening it and also fueling ongoing Apennine-belt seismic activity today. Our new study online at Jounal of the Geologucal Society.

High-precision seismic catalogs revealed a multi-segmented fault system in the 2014 Mw 6.2 Northern Nagano Earthquake.
This comprehensive approach underscores fault complexity and provides a framework for analyzing similarly segmented earthquakes elsewhere.

**Summary of the main results:**

New, site-specific GMPEs using the largest Campi Flegrei earthquakes from the past two years. We predict higher short-period (T < 0.2 s) structural demands and show strong attenuation beyond about 5 km from the epicenter. www.researchsquare.com/article/rs-5...
