"Since 12:06 a major seismic swarm has been underway ay Campi Flegrei consisting of at least ten shocks that occurred in rapid succession, including a M 4.4 off the coast of Pozzuoli and a M 3.5 just north of the city centre. The swarm is still ongoing, let's see how it evolves."

Dalle 12:06 è in corso un importante sciame sismico ai #CampiFlegrei composto da almeno una decina di scosse avvenute in rapida successione, tra cui un M 4.4 al largo di Pozzuoli e un M 3.5 poco a nord del centro cittadino. Lo sciame è ancora in corso, vediamo come evolve.

On May 10, 2025, a magnitude 4.1 earthquake shook residents from Nashville to Atlanta. This earthquake was widely felt due to the older bedrock in the southeastern US, which allowed seismic waves to propagate more efficiently than in the western US.

The eastern Tennessee Seismic Zone has an elevated rate of small quakes, with M5.1s in 2003 (Alabama) and 2020 (North Carolina). Did you feel today's M4.1 near Greenback, TN? Or are you in the area but didn't notice it? Please let us know! nitter.gq/USGS_Quakes/status/192…

Just experienced an unexpected earthquake right here in Knoxville, TN. Having lived in CA for ten years I have to say this one was impressive!! Felt like an explosion with a long amount of rumbling afterwards. @volcaholic1

Data from large earthquakes are critical to understand how the ground will shake in future large quakes on similar faults world-wide. Processed strong-motion data from the recent devastating M7.7 Mandalay, Burma (Myanmar), earthquake are available at ow.ly/SnfL50VOK7h

The seismic swarm after the 2025-04-23 M6.2 in the Sea of Marmara, #Turkey. There have been almost 300 earthquakes in the last 38 hours, with three ≥M5 aftershocks. The overall trend sees the current events "spread" along the Northern strand of the Northern Anatolian Fault, between the Central and the Kumburgaz basins. The infographic shows the events' area distribution with daily & magnitude data. #CitizenScience

Check out this @USGS computer simulation of the shaking from the magnitude 5.2 Julian, CA earthquake on 4/14 at 10:08am. More info: earthquake.usgs.gov/earthqua…. Over 7 million #ShakeAlert-powered alerts were delivered to cell phones. Did you get an alert? @USGS_Quakes @CaltechSeismo
