One of the largest earthquakes ever recorded sent tsunami waves across the Pacific. 🧪

Around 11:30 am local time, a magnitude 8.8 earthquake struck the offshore Kamchatka region at a depth of about 20 kilometers. The subduction zone quake caused severe shaking on the Kamchatka peninsula and triggered tsunami warnings and advisories around the Pacific. (1/n)

A magnitude 8.7 earthquake has just occurred off Russia's Kamchatka Peninsula, just a bit over a week after a magnitude 7.4 earthquake in the same area.
Multiple tsunami warnings and advisories are in place. Please check www.tsunami.gov for the latest information.
Seismogram and map from Station Monitor showing vertical ground motion from the July 29, 2025 magnitude 8.8 earthquake off Kamchatka. The seismogram was recorded at station R32K in Eaglecrest, Alaska, and marks the arrival of P waves, S waves, and surface waves. A yellow highlight shows the surface wave portion of the signal. The map below shows the path between the event epicenter off Kamchatka (marked “E”) and the station in Alaska (marked “S”), spanning 4003 km.
The magnitude 8.8 earthquake off Russia’s Kamchatka Peninsula is tied for the 6th largest ever recorded by modern instruments.

Happy FieldworkFriday! We strapped a GoPro to the skids of a helicopter for a recon flyover of St. Andrews Rock (STAR). The station is hard to spot on the ridge that the helicopter circles. Flying above Mt Rainier really puts into perspective how big this volcano actually is! youtu.be/PJ242pHcBGU

95% of wildfires are human-caused. One mistake with a chain, campfire, or tool can spark disaster. One less spark = one less wildfire.

Happy #FieldWorkFriday! OHAZ field technicians replaced the Steens Mountain wildfire camera this week. The camera is 10,000 feet above sea level, so it is exposed to extremely high winds and heavy ice in the winter. Now all OHAZ wildfire detection cameras are repaired and ready for fire season!

Director Harold Tobin with @SeattleTimes about the ongoing EQ swarm at Mt Rainier:
www.seattletimes.com/seattle-news...
It’s the biggest swarm since 2009, we’re closely monitoring the EQ activity, but we don’t see anything to elevate the level of concern about volcanic activity at this time.
On 7/8/25, the USGS & PNSN detected a swarm of earthquakes at Mount Rainier starting at 1:29AM PDT. Currently, there is no indication that the level of activity is cause for concern, alert level & color code for Mount Rainier remain at GREEN/NORMAL.
