Some good news from space, as the NASA-ISRO NISAR mission publishes its first synthetic aperture radar images of Earth. This spacecraft has a heckin' big antenna (a dish 12 meters across) for bouncing L- and S-band (25- and 10-cm) radio waves off the surface www.jpl.nasa.gov/news/nasa-is...

⚒️ 🧪 Were you one of the tens of thousands in the Bay Area woken up by the M4.3 earthquake last night? The earthquake occurred on the Hayward Fault, which runs along the east side of the valley. Learn more about what we know, and don't know, about the Hayward Fault and its seismic hazard:

Here it is: M3.0.

At 2:56 AM a magnitude 4.3 earthquake occurred near Berkeley, CA. The earthquake location is close to the Hayward fault. This earthquake generated light shaking across the Bay Area. The CGS continues to monitor the situation. www.conservation.ca.gov/cgs

#MSH45 | May 18, 1980 — 8:32 a.m. Geologists Dorothy and Keith Stoffel, with pilot Bruce Judson, make a final pass over Mount St. Helens. A M5.1 quake strikes. Ice and rock collapse into the crater. Below them, the north face heaves—then gives way. The largest landslide in recorded history begins.

Today’s M7.4 aftershock of the Kamchatka #earthquake was located in the Northern section of the mainshock rupture, where most aftershocks (in pink/purple) and foreshocks occurred. This event was also an interface thrust earthquake, but slip was concentrated at a greater depth. ⚒️🧪

Ever seen a “volnado” before? Check out this video from USGS of a whirlwind kicking up loose ash deposits along the active fountain and flow within the Halemaʻumaʻu crater of Kilauea! According to USGS, these whirlwinds have been documented during several eruptive episodes downwind of the eruption

How does lava sound when it comes to the surface of the Earth? Listen to a lava flow oozing out of its effusive vent high on the southwestern side of #Etna, 28 August 2025. That day no visits by tourists were allowed on the site, which permitted this (relatively) clean recording

⚒️ 🧪 A magnitude 6 earthquake struck northeastern Afghanistan just before midnight on August 31st. Vulnerable homes built of mud, brick, stone, and wood collapsed; the reported death toll has exceeded 800 people. Why do earthquakes occur here, what happened in this one, and why was it so deadly?

Episode 31 of the ongoing #Kilauea eruption began today at 2:04 p.m., and lava could be seen fountaining from the north vent. Initial fountaining was approximately 100 feet high, according to the Hawaiian Volcano Observatory. #HVNP

A M7.5 earthquake just struck a remote corner of the Antarctic Plate, below the Drake Passage. What’s going on in this fascinating part of the world? We wrote about it last May, after a M7.4 earthquake. We have made that post free to read, and added a few new maps and thoughts. ⚒️ 🧪

While everyone waits for the 31st eruption of #Kīlauea Volcano at Hawai'i Volcanoes NP... 🌋Kīlauea has had 30 episodes of lava fountaining in Halemaʻumaʻu crater, within the summit caldera, since December 23, 2024. This infographic summarizes the past 30 episodes of activity. USGS graphic.

Places where we've seen precursory activity include Iliamna volcano (AK), Mount Steller (AK), Nuugaatsiaq (Greenland), and Rausu (Japan). But most of the time, landslides like these do not give warning. The question of whether some do and some do not is a critical and fascinating one.

NISAR satellite is in the planned injection orbit. It will be gradually moved to the final science orbit over the next month and a half.

Liftoff! The NASA-ISRO Synthetic Aperture Radar mission has launched from Satish Dhawan Space Centre. #NISAR will scan the entire globe twice every 12 days to measure changes in Earth’s ecosystems, cryosphere, and land surface. “It’s orbiting magic.” —Alex Gardner, NASAJPL eos.org/articles/tra...

#NISAR will take 90 days to perform commissioning tests & reach its science orbit. “But as we progress, we’re going to get little peeks behind the curtains...It’s going to be transformational.” —Alex Gardner, JPL eos.org/articles/tra...

NISAR launch was successful today - “NASA-ISRO Satellite Lifts Off to Track Earth’s Changing Surfaces” - www.jpl.nasa.gov/news/nasa-is...

NEW: You may wonder why Japan’s 2011 mag-9.1 quake created a colossal tsunami that killed 18,000 people, while today’s mag-8.8 quake made a big, but not catastrophic, tsunami. For @sciam.bsky.social, I explore why. (Hint: it’s because the 2011 quake was SO much stronger.)

Another quick comparison of the 1952 #Kamchatka #earthquake from MacInnes et al. (2010) with today’s M8.8 event. The aftershock areas are similar, as well as one region of foreshocks. The updated USGS rupture model has a max slip of 10m versus 12m for 1952, with SW rupture direction. 🧪⚒️

⚒️ 🧪 What do we know about the M8.8 earthquake that struck offshore Russia yesterday? We explore patterns in the foreshocks and aftershocks, compare the USGS seismic catalog with a local seismic database, and compare the event to the great 1952 earthquake.

⚒️ 🧪 A M8.8 earthquake just ruptured the subduction zone offshore Russia’s Kamchatka peninsula. This is one of the world’s truly huge earthquakes, and a triggered tsunami is currently traveling across the Pacific ocean. This same fault ruptured on July 20th in a M7.4, and last August in a M7.1.
