The Matai’an landslide dam in eastern Taiwan has failed this afternoon (eos.org/thelandslide...), flooding Guangfu, about 15 km downstream focustaiwan.tw/society/2025.... Even in the middle of a typhoon, the resulting flood produced a detectable seismic signal at stations ~40 km away.

This article, based on a recent Seismological Research Letters paper from scientists at the Statewide California Earthquake Center (SCEC), examines occurrence of supershear earthquakes, the need for updated hazard planning & suitable building design to reflect risks: dornsife.usc.edu/news/stories...

Yet another Nat Cat job? Actually, we're searching for TWO experts, specialized in tropical cyclones or earthquakes. US or UK, remote work definitely an option. Great job for an ECR physical scientist looking to join the insurance/reinsurance industry! eedu.fa.em3.oraclecloud.com/hcmUI/Candid...

🌋 Excited to share my new essay in Aeon: one of the most underappreciated global risks isn’t an asteroid or supervolcano—it’s the eruptions we don’t see coming:

Volcano alert: Scientists discover a signal that could transform early warning systems - the role of shear-wave splitting: www.earth.com/news/volcano...

This paper by Meredith et al. (2025) examines global city exposure to volcanic hazards, using metrics such as population and distance to GVP Holocene volcanoes to quantify and rank cities at risk. This data has also been visualised through a web app. nhess.copernicus.org/articles/25/...

Just to illustrate how long waves from a #tsunami can keep going, this is a tide gauge record from Crescent City CA (known for its sensitivity to tsunami waves due to bathymetric and resonance effects) showing significant wave activity still continues 24+ hours after their first arrival. 🧪⚒️

Kamchatka earthquake highlights the advances in tsunami early warning systems 🌊 🛰️ BGS Prof David Tappin, Marine Geologist & tsunami expert explains how the Kamchatka event highlighted the improved mitigation measures now in place. www.bgs.ac.uk/news/kamchat...

This article, based on Yanites et al. (2025) in Science, discusses how hazardous events such as earthquakes, wildfires, & storms accelerate erosion & sediment transport, increasing sensitivity & risk of cascading hazards such as landslides & floods: theconversation.com/hurricane-he...

Earthquakes in eastern #Canada? June 23, 2010 - a damaging M5 #earthquake in western Québec was felt in Ontario, #Québec and as far away as Washington DC. It triggered landslides and produced the strongest shaking ever felt in #Ottawa (~60 km away): earthquakescanada.nrcan.gc.ca/pprs-pprp/pu... ⚒️🧪

On 17-18th June, explosive eruptions at Mt. Lewotobi Laki-Laki on the Indonesian island of Flores sent ash >11.5km above sea level. This highlights volcanic hazards on varying scales; pyroclastic flows & lahars threatening local communities, & ash leading to flight cancellations & delays.

The VAAC report for the Etna eruption today mentions a plume reaching 6,500 m / ~21,000 feet.

Pyroclastic flows at Etna have been confirmed by INGV ⚒️🌋

Pleased to announce the 4th major release of the @wsmproject.bsky.social, the biggest update of the database since the project began. With thousands of new data, the 2025 WSM brings the most comprehensive picture yet of Earth's present-day stress field. #Geomechanics W: www.world-stress-map.org

On 21 May 2025, a house was destroyed by a dramatic quick clay landslide at Sainte Monique in Quebec, Canada. Fortunately, no-one was killed:- eos.org/thelandslide... There is also excellent drone footage of the aftermath on Youtube, posted by Radio-Canada Info:- www.youtube.com/watch?v=G4JB...

In 2024, Europe saw average to slightly above-average fire danger for most of the year, with the highest values in September. Around 110,000 hectares burnt in Portugal that month, accounting for around a quarter of the overall total burnt area in Europe for the year. bit.ly/4ctJySA #ESOTC2024 #C3S

This is a photo of the surface rupture we saw in the webcam footage of the Myanmar #earthquake. The webcam was positioned on the opposite side behind the gate. Source is the YouTube channel that also posted the footage. 🧪⚒️ youtube.com/@sagaingeart...

Incredible footage of sudden ground displacement from the recent Myanmar earthquake. It took me a few watches to understand & believe what I was seeing!

We hope everyone attending European Geosciences Union (EGU) 2025 has a fantastic week and don't miss the following COMET talks and posters. You can check out the full hashtag#EGU25 programme on the EGU website www.egu25.eu

SEISMIC INFORMATION : SEA OF MARMARA (WESTERN TURKEY) 23 APRIL 2025 09:49 The following preliminary information is available for this earthquake: LAT/LONG : 40.840° North / 28.142° East DEPTH : 10 km MAGNITUDE : 6.2 Mw LOCALITY : Sea of Marmara, 75 km west of Istanbul, Turkey

USGS provides interactive ground motion maps for 14 earthquake scenarios on the Elsinore fault, ranging from M 6.8 to M 7.7 (many combinations of different fault sections) so you can see what shaking it is capable of producing in the future earthquake.usgs.gov/scenarios/ca...

🫨 Yeah, we felt it, too. Today's #earthquake occurred near the Elsinore Fault Zone and reached a magnitude of 5.2, according to scientists with @igpp-sio.bsky.social. You can view the seismic wavefield animation by Scripps Oceanography PhD candidate John Rekoske.

Friday's M7.7 Mandalay, Myanmar earthquake - do we need to rethink earthquake hazard models? A little summary and discussion - hopefully in relative simple terms - by me, over on LinkedIn: www.linkedin.com/posts/sphick...

Although the effects of today's Sagaing quake are most severe in places like Mandalay, shaking in Bangkok may seem surprising given it's ~1000km from the epicentre. This is due to long period ground motion, amplified by a deep sedimentary basin comprised of soft alluvial clay. (1/2)

IMO's models suggest the volume of magma accumulated beneath Svartsengi has exceeded the amount present before the eruption that began on November 20, 2024. It is anticipated that an eruption may start in Sundhnúksgígaröð with very short warning. Below latest IMO news:

With geoscientists keeping a close eye on the seismicity around Santorini over the past couple of weeks, this work by the BGS using machine learning to enhance detection & short-term forecasting for advising emergency services & at-risk communities is fascinating: www.bgs.ac.uk/news/artific...

A brilliant and comprehensive record of the volcanoes dotted around Europe, complete with their various characteristics and unique hazards to be aware of.

NASA's UAVSAR radar has detected that parts of the Palos Verdes Peninsula in Los Angeles County are sliding toward the ocean at rates up to 10 cm per week, following heavy rainfall in 2023 and 2024. ⚒️🧪 #geology #geohazards #remotesensing

For context, Geoscience Australia have updated their NSHA (National Seismic Hazard Assessment) Map, and two areas have been classified as higher hazard than the previous map from 5 years earlier. These areas don't suddenly have a higher chance of earthquake activity. Hazard ratings aren't prediction

A new paper in the journal Landslides (Li et al. 2025) explores a large landslide at the Xinjing open-pit coal mine in Inner Mongolia, which killed 53 people. It shows that measurable movement was occurring 18 months before the collapse. eos.org/thelandslide... Image by Planet Labs.

“After a wildfire, the hazard to the public is not over,” said Jeremy Lancaster, California’s state geologist. …The two major hazards after a wildfire are flash flooding and post-fire debris flows.” www.nytimes.com/2025/01/16/c...

Although this episode doesn't appear to be the precursor to an imminent eruption, the use of seismic signals & uplift to monitor magma movement & accumulation is an interesting area of study for potential forecasting applications (as explored during my MRes): en.vedur.is/about-imo/ne...

August's Nankai Trough quake & subsequent 'megaquake advisory' began discussions about what prompted the decision & what it means for long-term regional seismic hazard. Yesterday's nearby Mw6.8 event had no such advisory, despite a brief tsunami warning. Why? www.japantimes.co.jp/news/2025/01...

🧪⚒️ This seems to be an aftershock of the M7.1 that struck nearby last August. Recall that the M7.1 also led to a "megaquake advisory" by the Japanese Meteorological Agency, which we wrote about here: doi.org/10.62481/cea.... I believe (?) that the default cutoff for an advisory is M7.

Something to note about this morning's Tibet quake is the effect shaking had on buildings. >1,000 houses destroyed or damaged, mostly constructed from local materials like mud & stone, & although USGS Shakemap reports max. shaking intensity of MMI VII, local DYFI reports claim as high as MMI IX.

El Hierro provides an interesting test-bed for how multiple sources of renewable energy are used together; wind, hydro-electric, & geothermal, to end reliance on fossils fuels. It'd be interesting to see how this can be scaled up using other sources such as solar: www.theguardian.com/environment/...

Good read about scientists working on the #earthquake and #tsunami #hazard posed by the Cascadia subduction zone ⚒️🧪
