Mount Tambora Is Still Active, but It's Not Likely to Have a Devastating Eruption Again Learn more about the area around Mount Tambora and how, even though it was once the site of the largest eruption on record, the next massive eruption probably won't come from there.

Monitoring stations detect small magnitude earthquakes at Mount Rainier An earthquake swarm that started at Mount Rainier on July 8, 2025, is the largest ever recorded at the volcano.

Mount Rainier has seen 391 located quakes since a swarm began July 8, surpassing 2009’s in size and energy. Activity is declining. Quakes are 2 to 6 km deep with no ground deformation or signs of magma.

Lava, steam... and a little lesson in physics. Exploring the Leidenfrost effect in volcanic eruptions Over the last few days, impressive images of Etna erupting have once again captured the world's attention. Columns of ash, lava fountains, incandescent flows: the Sicilian volcano, one of the most active in Europe, reminds us of its power. But watching lobes of lava rush down the snow-covered slopes of the Valle del Bove, generating lahars (mudflows of volcanic origin composed of water and volcanic debris) and producing intense clouds of steam upon contact, an unexpected question came to mind: What connection could there be between a volcanic eruption and a water droplet “dancing” on a hot plate?

The Silent Pressure Beneath Stealth volcanoes erupt without warning—but a new model of Veniaminof in Alaska shows how to spot their quiet buildup before it’s too late.

Not all volcanoes shout before they erupt. Some whisper. Now scientists can finally hear them. #VolcanoMonitoring #StealthEruption #Geoscience

Mount Etna erupts The Copernicus Sentinel-2 mission has captured a dramatic image of Mount Etna erupting on 2 June 2025 when a massive plume of ash, gas and rock suddenly burst from Europe's largest active volcano.

Mount Etna erupted on June 2, 2025, sending a massive plume of ash, gas, and rock into the sky. ESA's Sentinel-2 satellite captured this dramatic event. Here's a view of Etna's eruption from space

NASA satellite images could provide early volcano warnings Scientists know that changing tree leaves can indicate when a nearby volcano is becoming more active and might erupt. In a new collaboration between NASA and the Smithsonian Institution, scientists no...

NASA scientists are studying whether changes in vegetation in satellite data, like greener trees from volcanic carbon dioxide, can signal early volcanic unrest. This method could help improve eruption forecasts in places with limited ground monitoring.

Deformation (volcanology) (Volcanology 🌋)

In volcanology, deformation refers to the change in the shape of a volcano or the surrounding landscape due to the movement of magma. This can be in the form of inflation, which is a response to pressurization, or […]

A switch to low-frequency tremor can signal magma movement, not necessary relief. Misinterpreting this could be risky. We need more analysis. #VolcanoMonitoring #Santorini — and don't forget the fish. They've left for a reason. Just my opinion.

Satellite Data Reveals Early Warning Signs of Anak Krakatau’s 2018 Eruption and Tsunami A comprehensive analysis of satellite imagery has uncovered that Indonesia's Anak Krakatau volcano exhibited significant ground deformation for over a decade prior to its catastrophic 2018 eruption and subsequent tsunami, suggesting that such data could be pivotal in forecasting future volcanic collapses.

Satellite analysis reveals Anak Krakatau showed warning signs years before its 2018 eruption and tsunami, highlighting the need for advanced monitoring to prevent future disasters.
