⚒️ 🧪 A M6.5 earthquake struck near Acapulco, Mexico today, triggering warning systems and causing tall buildings in Mexico City to sway. How does this event fit into the larger tectonic picture - and what kinds of earthquakes might we expect here? earthquakeinsights.substack.com/p/m65-subduc...

Some good news for the new year: the Museum of the Earth has avoided foreclosure and paid off its mortgage, thanks to the generosity of donors. If you helped, either by donating or raising awareness, please accept my personal gratitude. It mattered. ❤️ And if you ever visit Ithaca, stop by!

Did you ever wonder how Kyle and I ended up where we are - independently writing Earthquake Insights, rather than employed by a university? We talk about it in this interview with Shawn Willsey on his Youtube channel, Geology Explained. www.youtube.com/watch?v=7_-G...

🚨Extremely short notice: Looking for prospective PhD or postdoc w/ geological engineering or modelling experience, w/ interests in mountain geohazards for project focused on landslide-triggered tsunamis in subarctic w/ me & @geocron.bsky.social 🧵 🧪⚒️ Pls share! nserc-crsng.canada.ca/en/news/laun...

⚒️ 🧪 A swarm of earthquakes has been rattling the Bay Area since mid-November. This is only the latest of various swarms over the last half-century. What’s going on with this swarm, and how does it compare? (Plus, the post includes a bonus video of our cutest kitten yet!)

⚒️ 🧪 A paper in Science today highlighted a "progressive eastward rupture of the Main Marmara fault toward Istanbul." My thoughts on what a damaging Istanbul earthquake might look like, and whether recent earthquakes tell us something new, are in this article in the NYTimes:

However! They have FROZEN FOUNDATION FUNDS within days of the Regents' vote, despite the fact that there are commitments that have to be paid... such as student fellowships for the spring semester. Students promised employment for the spring were also abruptly notified they had none.

One graduate student just relocated his family with small children to Lincoln, and was told this week that he will in fact not be paid in the spring.

The things I am hearing about mismanagement out of @unlincoln.bsky.social are close to unbelievable, and I hope this is covered by all the news networks, from @nebpublicmedia.bsky.social to others. Apparently they have made NO plans for handling the shutdown and elimination of departments.

Want to do some good this holiday season? Consider supporting two hard-working earthquake scientists who gave up their paid faculty positions to make rapid earthquake analyses accessible to the public. Bonus: you can read out archive of 300+ posts and become pretty expert yourself!

As ever, full of insights. And a 3D model to play with.

The results are in! We have updated the post with an initial InSAR image for this earthquake, showing ground deformation in this event. Scroll to the end to find the new text with figures!

he first Sentinel1 images are in after the Alaskan M7 earthquake beneath Hubbard Glacier - no shortage of new landslides. Below are 28/11 and a 9/12 images! @watershedlab.bsky.social @davepetley.bsky.social

Again, Kyle and Judith provide a great summary of the science around this earthquake

⚒️ 🧪 Japan just issued a “Subsequent Earthquake Advisory” following a M7.6 earthquake offshore Honshu. What does that mean? Also: what happened in the earthquake, and why did it trigger a tsunami evacuation, with alerts of waves “up to 3 meters high”? earthquakeinsights.substack.com/p/m76-earthq...

⚒️ 🧪 Have you been watching the little swarm of earthquakes east of San Francisco (most recently, M3.7)? Here's a map and timeline.

M 7.6 earthquake 73 km ENE of Misawa, Japan earthquake.usgs.gov/earthquakes/...

Here is the latest tsunami information for the M7.6 earthquake that just struck offshore northern Japan. The warnings are for waves up to 3 m, but the highest waves measured so far are <0.5 m. It is still possible for larger waves to arrive. 1/2 www.jma.go.jp/bosai/map.ht... ⚒️ 🧪

"Rather complicated" is the TL:DR for this great post from @judithgeology.bsky.social . Strap in for the Bell Telephone connection, a deep dive into geologists' beach balls, and a terrane wreck. bsky.app/profile/judi...

Yesterday, a M7.0 earthquake struck the Alaska-Canada border, directly beneath the Hubbard Glacier. Aftershocks reveal an unmapped fault in this already complex area. Read our post for more, & also: What happens when a fault offsets a glacier? Is the glacier named after one of my ancestors? ⚒️ 🧪

It's over. Despite the fact that the academic council recommended against it, despite the fact that the program brought in more tuition than it cost, and despite the fact that Nebraskans need & deserve this expertise, Earth & Atmospheric Sciences will be cut. www.dailynebraskan.com/news/adminis...

Magnitude 6.8 earthquake ten minutes ago along Yukon/Alaska border on the Fairweather Fault. I am guessing this will result in some big landslides. 🧪⚒️ earthquake.usgs.gov/earthquakes/...

A M5.8 earthquake struck NW China today - an aftershock of the 2024 M7 Wushi earthquake. Although slip in the M7 mainshock did not reach the surface, a M5.7 aftershock a week later produced a remarkable surface scarp. Did the latest M5.8 do the same thing? We're waiting for data to find out. ⚒️ 🧪

This year, the NSF funded 35% fewer grants in geoscience, with 25% less money. Meanwhile, the Office of the Director spent almost three times as much money as in a regular year. www.nytimes.com/interactive/...

An excellent visualization of the subduction zone up here and the location of the earthquake. Thank you for sharing @judithgeology.bsky.social! 🧪⚒️ #earthquake #alaska

⚒️ 🧪 This morning, a M6 earthquake struck at ~70 km depth near Anchorage, Alaska. Earthquakes are a regular part of life here: this is a subduction zone, with earthquakes deepening east to west. M6 earthquakes fall well within the range of "normal". USGS page: earthquake.usgs.gov/earthquakes/...

⚒️ 🧪 A M6.6 earthquake just struck the subduction zone offshore Sumatra, causing some damage and injuries on Simeulue Island. How does this event fit into the mosaic of large earthquakes that have occurred on this fault over the last few decades? earthquakeinsights.substack.com/p/m66-earthq...

What should you do to prepare for earthquakes in Bangladesh — especially if you don’t live there anymore? I had the pleasure of chatting with Anil Wasif from BacharLorai Global, a nonprofit aimed at empowering Bangladeshis worldwide, about the recent quake, seismic hazards, and how to do better.

Some footage from Bangladesh, post M5.5 earthquake. This is probably lateral spreading and slumping associated with earthquake-triggered liquefaction. Liquefaction is a huge hazard in Bangladesh, because so many people live in low-lying areas on saturated sediments. ⚒️ 🧪

A M5.5 earthquake killed at least ten people in Bangladesh today. What made this moderate event so deadly? And what do we know about seismic hazards in the country? ⚒️ 🧪 earthquakeinsights.substack.com/p/bangladesh...

Hopefully, if this does come to pass, any new construction will take seismic risk into consideration. Tehran is an earthquake disaster waiting to happen. Retrofitting old buildings is much harder than building new ones that are more resilient.

This is giving me Brawndo vibes. (It's got what plants crave!)

Earthquake Insights is making *almost* $20k a year - which is simultaneously more than I ever thought it would make, and not nearly enough to raise a family. 1/5

Are there any other geological map stamps??? I have a sudden urge to collect geology-themed stamps!

In the last 11 days another 102 donors have given >than $40,000, with some other donations in stock waiting to become available for use. PRI can make it with your help! Please continue to share with your networks for potential donors so we can keep the museum and its online resources available!

Something is terribly wrong in the book my 7 year old is reading.

Tectonic plate puzzle anyone? 🌎 Made by me, one at a time. I’m planning to have a really limited number available before the holidays - if you want to find out when I do, sign up to my newsletter! I will share them through it first. Sign up > www.luciaperezdiaz.com#newsletter (No spam, I promise)

Wow! I am currently experiencing serious underwater-seismometer-envy. This is so cool.

The underwater seismometer network is so great, as evidenced from yesterday's EQ off-Tohoku. Reposting unofficial visualization by x.com/kotoho76/sta...

⚒️ 🧪 A M6.8 earthquake struck offshore Japan today - another large earthquake from the subduction zone that produced two recent great earthquakes. The earthquake was preceded by a "cascade up": foreshocks progressively increasing in maximum magnitude. What do we know? What might happen next?

If you like to read about earthquakes, and think it is important for these kinds of analyses to be available, please consider becoming a paid subscriber! We offer all of our recent posts for free, but need support to make this work sustainable.

A fascinating read to learn more about the Japan earthquake and the region where it occurred.

Un #sismo M6.8 sacudió la costa de Japón hoy, en la misma zona de subducción que el grande de 2011. Un “pequeño” #tsunami llegó a tierra con olas <0.2 m; la mayor, 50 min después, recordatorio de que los #tsunamis pueden durar y llegar en varias olas 🌊

Today's Japan M6.8 is in an interesting spot: the zone of "missing" slip just north of the very large shallow rupture in the 2011 M9.
