A remarkable finding has emerged in #Italy, where the remains of a luxurious #Roman villa have arisen from the waters of #LakeFusaro, which is near #Naples. This phenomenon has been attributed to #bradyseism, which is a geological process brought about by the movements of #magma or hydrothermal fluids beneath the Earth’s surface.

"The harmonic seismic vibrations that indicate possible volcanic activity on Santorini began suddenly on Friday night and stopped abruptly, according to the Euro-Mediterranean Seismological Center. “We hear some noise. We cannot be certain what is happening,” the center posted on X."

Map of northeastern America with tectonic features and seismic stations. The green rectangle marks the study region, and black triangles are the TA stations used in this study. Yellow diamonds are kimberlite locations. Red triangles represent the New England seamounts (NES), Cretaceous plutons in the White Mountains (WM) in New Hampshire and Monteregian Hills (MH) in Quebec, and Eocene volcanoes in northwestern Virginia. Blue curves indicate the Appalachian front and the Grenville front. The white dashed line shows the GM hotspot track. The Midcontinent Rift (MCR) and the Ottawa-Bonnechere Graben (OBG) are outlined in orange. The inset shows the current locations of the GM and CV hotspots in the Atlantic Ocean.

Maps of Vsv, radial anisotropy, and azimuthal anisotropy at selected depths. (a–c) Maps of shear wave velocity superimposed by azimuthal anisotropy (black bars). (d–f) Maps of radial anisotropy superimposed by azimuthal anisotropy. The bar length is proportional to the strength of azimuthal anisotropy; the bar orientation is the fast propagation direction of the S wave. White diamonds are the kimberlite locations. Red lines mark the locations of the vertical profiles AA’ and BB’ shown in Figure 3. The dashed white circle marks the area of circular azimuthal anisotropy. A1–A4 mark positive radial anisotropy regions.

photo - An ash plume billows from the crater atop Mount St. Helens hours after its eruption began on May 18th, 1980, in Washington State. The column of ash and gas reached 15 miles into the atmosphere, depositing ash across a dozen states

photo - Mount Rainier, a snowcapped volcano, looms over Puyallup Valley near Orting, Washington. The prospect of a lahar — a swiftly moving debris flow caused by melting snow and ice typically during a volcanic eruption — poses a threat to surrounding communities.

Two new studies agree that sulfur is crucial to bringing gold from deep in Earth’s mantle to the surface. But they don’t agree on which type. Read more from @ScienceAlert
