Philippines earthquake: tsunami warning issued after 7.4 quake hits Mindanao

The “problem” with vaccines? They so effective at preventing deaths that they create generations of people that question whether disease was a problem in the first place because they have never experienced the horrors of a world without vaccines.

🚨I am very honored to announce that I’m starting as a Marie Sklodowska-Curie Fellow at the University of Lisbon, funded by the European Commission 🚨. I am grateful to NCSU where I honed my skills in Quaternary Geochronology and all my USA colleagues who I work with in Earthquake Geology. ☺️🌍

🌟FREE TO READ #KAMCHATKA #EARTHQUAKE PAPERS🌟As a service to researchers working on the 2025 M8.8 Kamchatka earthquake, we have curated a list of papers related to the region, free until until 22 August www.seismosoc.org/news/free-to... ⚒️🧪

The aftershock zone of today’s M8.8 Kamchatka megathrust #earthquake is comparable to the rupture area of the 1952 rupture zone from Macinnes et al. (2010). At a rate of 8 cm/year, the accumulated slip of 6 m since 1952 matches with the preliminary rupture model of today’s earthquake pretty well. 🧪⚒️

Incredible shrinking Cone of Uncertainty! Kartina 2005 vs Helene 2024. Dramatic improvement in hurricane forecasting due to expertise of NOAA scientists at NHC & AOML. Since 2005 forecast error on 5-day track has decreased by ~50%! We often take these accurate forecasts for granted but... 1/

I talked to a NOAA colleague yesterday who told me that 75% of the federal employees of his division have left and he’s worried about their ability to get work done even if Congress funds NOAA at some level. The devastation to science will be felt for generations.

Seeing Blatten buried again and again, from every angle... Properly staggering! 😮😱

My latest @nature.com story shares the human stories behind the massive job loss and brain drain facing US science. The quote I still can't get past: "We want to offer scientific asylum to our colleagues,” said Eric Berton, president of Aix-Marseille University in France.

Excellent reporting of a tragic story. So many mishaps, not the least of which was the NC legislature’s decision to eliminate a crucial landslide mapping program for 7 years under pressure from real estate interests.

#MSH45 | May 17, 1980 "I own a piece of the rock." Spirit Lake property owners gather in Toutle, ready for a showdown with officials, but Gov. Dixy Lee Ray will grant their wish. State Patrol Chief Robert Landon informs residents that everyone must sign liability waivers and be out by 6 p.m.

9 people were killed in a tornado last night in KY. The NWS office responsible for that area has faced some of the most extreme cuts by the Trump administration, including the loss of overnight forecasting. Last night, they were rushing to find help for the office. www.nytimes.com/2025/05/16/w...

You have to watch it multiple times, to see everything that is going on. Look to 1) co-seismic displacement right of the fence, the ground will move towards your right, indicating that it is a right-lateral displacement. (continues and feel free to add anything more if you see it)

Apparently surface rupture during the Myanmar 2025. I'm very surprised by the weak shaking along the rupture. I'm not sure if this is the main rupture (I would say no - nonetheless, VERY COOL). Author unknown, location Thazi (to be confirmed)

Check out this nicely done (and short!) USGS Coastal and Ocean Science video about our Cascadia earthquake-driven subsidence paper 🌊🌊🌊 USGS news release is here: www.usgs.gov/centers/pcms...

Staff members at the US National Science Foundation (NSF) were told on 30 April to “stop awarding all funding actions until further notice,” according to an email seen by Nature. https://go.nature.com/44Ugf9V

Not attending #EGU25 but I'm a co-author in a few abstracts. I highlight this poster presented by PhD candidate Dennis Wolf. Check it out Friday, 2 May in the morning Hall X2 | X2.52. He is doing a great work! (Next year, I will be at EGU, I promise!)

This is just horrible...

Another video from the Myanmar Mw 7.7 quake. Now we see the railway tracks (Pyinmana, Myanmar) bent and severely deformed.

The whole #MyanmarEarthquake rupture in one interferogram! This is three consecutive wide swath frames of ALOS-2 data, provided by JAXA through agreement with NASA. The line-of-sight (LOS) is ~perpendicular to fault strike, so most of what you see is vertical motion at bends and steps of the fault.

I think I don't have any more papers to review (ok maybe one). A long year where I reviewed many papers is completed!

this is the best post of the day!

since we are all doing this, here is my proof of defending a Holy Trinity

Absolutely amazing video. Direct displacement of a drainage/channel: it is possible to see a right lateral displacement of the thalweg of about 1.5 to 2 m. It is also possible to see the fault plane exposed! Credit: okarun011 on TikTok

Felipe Vera of @gfz.bsky.social shows an initial bilateral subshear rupture, yet the southward portion propagated much more at supershear velocities, cumulating to a "well over 400 km" long rupture! www.linkedin.com/posts/freder...

Given that 2025 Myanmar earthquake likely ruptured at supershear speed for considerable distance, I tried Vallée & Dunham (2012)'s method to identify potential Mach cone. I selected the M 5.1 aftershock whose USGS moment tensor is similar to that of the mainshock.

This matches very well with traces of the surface rupture visible a few km to the north on the high resolution Planet SkySat images (thank you Planet!). The offset road is the northernmost point on the overview, and I measured about 4.5 m of offset there.

Also fits with these images that I found on twitter, from Heung Min Son (@heungburma) and approximately located in Sagaing.

Updated map for M7.7 #Myanmar #earthquake now incl. Thai network aftershocks (in purple) and the extent of the USGS slip model (little slip on most S 75 km though). Aftershocks appear concentrated near epicenter and at S end of rupture (and past?). Central section (original gap) less active. 🧪⚒️

Good thread!

Regarding the Mw 7.7 Myanmar earthquake: to be confirmed, but it seems the segment that ruptured was at least partially a "seismic gap". The 1st image is figure 1 from Xiong et al 2017 doi.org/10.1002/2017... and the 2nd image is from Hurukawa & Maung 2011 doi.org/10.1029/2010...

In my case, it should be: “how is this quartz-rich??? There is cleavage!!! How do they expect me to extract 10Be from this piece of &$&@?!?” And then thinking about hitting them saying “sampling MATTERS! Learn your f$& mineralogy and petrology!” There! Stop complaining about geochronology!

I do remember learning that the K-Feldspar was pink.

I'm reading news about grad schools rescinding admissions offers and faculty searches being cancelled. And... these are the people were students five years ago, in high school or college or grad school, when they were sent home at the beginning of COVID lockdowns. And now I'm crying.

Quick little health-related thread: There are measles outbreaks happening in the US & Canada because of pockets of very low vaccination rates. I wondered if maybe I might need an update to my vaccines. I got them in the usual way as a kid, but sometimes immunity doesn’t last. So I asked my doctor.

Consider attending IAGA/ IASPEI 2025 in Lisbon. It has a really good scientific program and it is in Lisbon. Do I need to say more? iaga-iaspei-2025.org Abstracts deadline March 12!

This article touches important points. We need to step back and see outside of the Plato cavern. Nonetheless, things are roling and we must be aware of it. Stay STRONG 💪

I breaks my heart to see all of this impacted.

There are two very cool things (to me) about this paper. The first is just the technique (full-waveform inversion) the other is finding remnants of tectonic plates from 100+ Myrs ago in the mantle. 🧪⚒️ www.nature.com/articles/s41...

Happy “Large Boulder the size of a Small Boulder” Day to all those who celebrate.

Even when you know how magnitudes work and so how big a M9 earthquake would be, it's still hard to fully fathom an event like 1700 Cascadia. The rupture area is just SO huge.
