EarthScope engineers and Field Safety mountaineers successfully serviced GPS stations in the ablation zone of Taylor Glacier in Antarctica. With a pole-mounted pulley setup, they lowered the 800-lb stations back to the surface—no small task on glacial ice! #FieldworkFriday

📷 Nick Bruno/EarthScope
Three team members in cold-weather gear operate a pulley system attached to the station frame, preparing to lift heavy batteries from the enclosure. A tilted NetR9 GPS station with multiple solar panels stands on ablated glacier ice, with steep ice terraces and rocky valley walls behind it. A lowered and re-leveled GPS station sits on the glacier surface near exposed ice cliffs, with tools and backpacks set on the ice under low clouds. A small group works around the leaning GPS station on the glacier surface, adjusting ropes and equipment with the steep valley slope rising behind them.

Recent Earthquake Teachable Moment for the magnitude 7.6 earthquake offshore Aomori Prefecture, Japan

Teachable Moment presentations capture the opportunity to bring knowledge, insight, and critical thinking to the classroom following a newsworthy 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”?

GPS stations in Yellowstone can clearly show how the ground moves, but this simple measurement requires the data to go on a complex journey.

A magnitude 7.6 earthquake struck off the east coast of Aomori Prefecture in Japan, prompting tsunami advisories for parts of Honshu and Hokkaido. Japan lies in a tectonically complex area at the intersection of four tectonic plates, making it a highly seismically active area.

Fortunately, the M7.6 earthquake struck at low tide, reducing the impact of the tsunami (itself smaller than feared, max 70cm observed). 1/2

Did you feel shaking in Yukon at 1:41 p.m. MST today? That was a M7 #earthquake near the seismically active YK-AK border and 250 km to the west of #Whitehorse.
Shaking was felt across much of Yukon and southeastern AK.
Details and report shaking:

The Earth is constantly being whispered to by natural signals, tiny electric and magnetic waves. By studying how these signals move, magnetotellurics helps scientists see underground. Metal-rich rocks or hot water let the signals flow easily. Dry, solid, or dense rock blocks or slows them.

Comparing seismic data and drone imagery from the 2021 eruption at Geldingadalir in Iceland shows that ground tremor spikes track bursts of bubble-bursting and lava spatter, not the lake’s rising or falling surface.

For two decades, GPS station P056 in Porterville, California has been steadily tracking the ground moving down. Since its installation, the ground has subsided over 3.5 feet. Located in central California’s San Joaquin Valley, P056 records subsidence driven by long-term groundwater overpumping.
