El informe de USGS por el sismo reciente en Yellowstone se puede ver en: earthquake.usgs.gov/earthquakes/...

#sismo #temblor
Las calderas que en estos momentos tienen sismicidad interesante y deformación constante son:
- Laguna del Maule (Chile)
- Campi Flegrei (Italia)
y ahora, #Yellowstone (USA) con un M3.9 a 800m de profundidad focal
Alguna otra que falte por mencionar?

1 April 1946 12:29 UT
Mw8.6 earthquake near Unimak Is. (Alaska) ruptured a segment of the Aleutian megathrust. A tsunami killed 173 people, 159 of them in Hawaii. This EQ led to the creation of the Pacific Tsunami Warning System.

New platform, same passion! 🌋 Just landed on Bluesky and it's time to repopulate my feed—starting with some 'vintage' research! Throwback to our 2024 paper on anisotropic #seismictomography of #EtnaVolcano, unraveling its complex dynamics. Still a hot topic!🔥

Sismo 27 Febrero 2010, Mw 8.8, Chile Central, Piso 10, Santiago.

Earthquake intensity map by USGS of the 2010, 27 Feb, M 8.8 Bio-Bio, Chile earthquake.

Surface projection of the slip distribution superimposed on GEBCO bathymetry. Thick white lines indicate major plate boundaries [Bird, 2003]. Gray circles, if present, are aftershock locations, sized by magnitude.

The Feb 27, 2010, M 8.8 Bio-Bio, Chile, #earthquake was caused by shallow thrust faulting along the Nazca and South America plates converging at 71 mm/yr. The fault rupture, over 100 km wide and nearly 500 km long, spread from 25 km deep, causing severe shaking and a tsunami. (1/3) #OTD ⚒🧪

Is a key ocean current system slowing down? A new study adds to the debate A team of researchers reconstructed a critical ocean current system — called the Atlantic Meridional Overturning Circulation, or AMOC — in computer models and found no evidence of long-term weakening ...

🌊 WaPo on a new attempt to reconstruct past AMOC changes: www.washingtonpost.com/climate-envi...
And LiveScience: www.livescience.com/planet-earth...
Different to our past work is the shorter time interval, in which we also don't find a significant weakening: www.realclimate.org/index.php/ar...

MAJOR SPLIT-TYPE SUDDEN STRATOSPHERIC WARMING IN THE 06Z GFS! 🚨 🤯

Ok, it's at 330 hours, and it's just one member, so this is not a forecast.

BUT, it's inescapable that forecasts are now drifting toward a weaker vortex, consistent with strong wave forcing from the Scandinavia-Greenland pattern.

A M5.8 (local confirmation); M5 .1 USGS. It occurred in Guayaquil-ECU at a depth of 84km and was an interplate EQ. It was a strong tremor due to its depth and epicenter.
Also, I was at the epicenter and I confirm that it was strong as it was interplate and the first +M5 in Ecuador-2025

Is it possible Earth captured the Moon? Maaaaaaybe. The Giant Impact hypothesis still reigns, but it’s worth looking at other ideas

4.5 billion years ago or so, a planet the size of Mars slammed into Earth and the debris that splashed out eventuially coalesced to form the Moon.

…or did it?

… well, yeah, probably. But a new paper posits Earth-sized planets can capture moons.

What happens in China never just stays in China. There is a surge in influenza A in the U.S. as well this winter. We rarely test whether the virus is conventional flu, or H1N1 swine flu, H5N1 bird flu. But the crowded ERs seen in many places are indications something is afoot. 🧵
