Kilauea is rumbling…
“Rates of seismicity & deformation increased ... it is not possible to say with certainty if this activity will lead to an eruption, the activity may remain below ground. However, an eruption in Kīlauea’s summit region is one potential outcome.”

Interesting summary of the ongoing saga of the moving mud pot in Niland, near the Salton Sea in Southern California. I had just started a geophysics project in that area when I left my faculty position, it would have been fun to try and figure this out!

Impressive video of a landslide due to mine blasting in Bosnia and Herzegovina a few weeks ago, which led to a small tsunami/seiche

Some more updates on the New Jersey earthquake: the regional moment tensor indicates a M4.8 and a mix of strike slip and reverse faulting at a depth of 7km. No aftershocks have been reported yet, which is a bit surprising for an event of this size.

Map of historical seismicity of region around today’s M7.4 earthquake in Taiwan shows numerous M7+ events in the past century within 50 km of epicenter. Aftershock pattern (in purple) indicates slip may have propagated to NE, possibly offshore.

A new eruption has started in Iceland, close to the previous fissure. One of the live webcams that shows several views and a map can be found at: https://www.youtube.com/live/804nPrAUAxg?si=nW5ebaHckybDbOqq

“What’s happening is unprecedented,” Rancho Palos Verdes’ contracted geologist, said this month after reviewing more than 16 years of data. “We haven’t seen this kind of movement in the upper areas of the landslide in the whole history of monitoring the #landslide.”

M5.7 deep (35-40 km) #earthquake near Pahala, #hawaii. Two interesting hypotheses as to the origin of these events: flexure of the lithosphere due to weight of the overlying #volcanoes or #magma migrating into the Pāhala area & stalling at depth, pressurizing the region

The #meteorite hunt is on near Berlin!
“In the late-night hours of January 21, 2024 – 90 minutes before impact over European skies – NASA said a small #asteroid would hit Earth’s atmosphere. The #space rock struck on schedule above an area west of #Berlin, Germany.”

An updated map of both of today’s new fissures in #Iceland, in red straight lines. #lava from the newest fissure is now reaching the first houses in #Grindavík.

This aerial photo is doing the rounds and is credited to the #Iceland police department, but I haven’t been able to find the original post.
If real, it does give a good indication of how close the current flows are to the town of #Grindavik.

This map shows the location of the current #eruption in #Iceland (red line) relative to the previous flows (purple) and the protective berms (orange), indicating it has cut through one of those #berms already. The current flow is less than 500 m away from the town of #Grindavík.

Watching the live #webcam feed of the current #Iceland eruption.
Unfortunately, it appears that this #eruption will have much more of an impact on the local population than the previous one, with the #lava crossing the protective berm that was built earlier.

Interesting paper about the Holocene Storegga #tsunami caused by a large #submarine #landslide off the coast of Norway: it resulted in run-up heights of up to 3–6 m around mainland UK & coincided with a large decline in the Mesolithic population in N. Britain.

Today’s M7.5 earthquake in Japan was located at or near the site of a recent intense seismic swarm and transient deformation at Noto Peninsula, which is a non-volcanic/geothermal area far from major plate boundaries.
