@IGSorg correction, 2100 km away

High-rate GNSS station MIZU in central Honshu, Japan, recorded the M8.7 Petropavlovsk-Kamchatsky, Russia earthquake, 2500 km from the epicenter. A peak motion of over 7 cm is seen in the east component. @IGSorg

🎉 Congratulations to Professor Melisa Diaz on being named a 2025–2027 CIFAR Azrieli Global Scholar! 🌍 She's one of just 12 early-career researchers worldwide recognized for her bold, interdisciplinary work. 👏 @cifar.ca bit.ly/4mKyUM7

An assistant professor in @osuearthscience @ASCatOSU, @bwcphd was awarded a 2025-26 @FulbrightPrgrm U.S. Specialist grant to @EPNEcuador in Quito, Ecuador to improve early warning for tsunami hazards for residents in the Ecuador subduction zone. #Fulbright oia.osu.edu/news/2025/04/1…

Peak displacement of 20 cm recorded on @IGSorg GNSS station CUUT in Bangkok today from the devastating M7.7 earthquake near Mandalay, 1000 km from the source.

The surface wave from the M7.6 Cayman Islands earthquake was recorded well on GNSS station SSIA in El Salvador, 840 km away. Peak motion of almost 7 cm. @EarthScope_sci

Upwards of 60 cm of peak motion recorded in Port Villa, Vanuatu during today's M7.3 earthquake. Subsidence of around 10 cm. Real-time GNSS solutions from CWU. @IGSorg

Excellent GNSS recordings in real-time for todays M7 earthquake offshore Petrolia. Peak displacement was just above 40 cm for P157. Solutions from CWU PANGA @EarthScope_sci

U.S. Earthquake Early Warning System Gets a Major Upgrade eos.org/articles/u-s-e…

The M5.2 in Lamont, California this morning was recorded nicely on 5-Hz GNSS site WGPP, roughly 15 km SE of the epicenter. Shown are the velocity observations computed from time-differenced carrier phase observations. Peak ~ 15 cm/s @EarthScope_sci

West Coast residents can now benefit from satellite data in their earthquake early warning system. @USGS_ShakeAlert is now leveraging GPS data, the USGS announced this week. thenationaldesk.com/news/americas-…

In light of the news adding GNSS to @USGS_ShakeAlert, I wanted to reshare the following video of the expected performance of GFAST for the Tohoku earthquake. If a similar event occurred in Cascadia, this gives you a sense of the performance youtu.be/ZHZpUpTJRu8?si…

Today #ShakeAlert #EEW gets a boost! It's even more ready to take on the biggest quakes. It now includes Global Navigation Satellite System (GNSS) sensors that detect Earth-surface movement via satellite. GNSS includes the well-known US-based Global Positioning System (GPS).@USGS

A long journey to get here, its such an honor to see GFAST finally in production in @USGS_ShakeAlert

Seattle aurora coming in strong

Congrats to my student @jensendegrande_ for winning one of the @AGUGeodesy section OSPA awards at the Fall meeting!

@SeismoSue youtu.be/ZHZpUpTJRu8?si… GMT videos are pretty awesome too

Stunned & saddened to hear that Paul Wessel passed away on March 26. Only 64. Such monumental contributions to science. As a tribute to Paul, let’s see those GMT figs. (Not my best but one I can put my hands on right this second)

Very sad to learn about the passing of Paul Wessel nittedal.vareminnesider.no/memorial_page/…

A very crude offset estimation for @IGSorg station TWTF for the M7.4 earthquake in Taiwan. Due to the timing of the event, only a few 30-s GNSS samples are available after the earthquake near the UTC day boundary. ~20 cm southward motion with ~10 cm subsidence
