Submarine volcanoes or those deep in our oceans can release extremely powerful energy, high enough to power a continent, new research suggests. It was previously believed that underwater volcanoes were much less violent than those on land due to relatively…
Eruptive activity at Semisopochnoi has gradually increased over the last 24 hours, the Alaska Volcano Observatory (AVO) reported at 21:48 UTC on April 22, 2021. Satellite views of the volcano show a continuous plume extending 80 km (50 miles) to the south at…
New activity/unrest was reported for 5 volcanoes from April 14 to 20, 2021. During the same period, ongoing activity was reported for 18 volcanoes. New activity/unrest: Karymsky, Eastern Kamchatka (Russia) | Krysuvik-Trolladyngja, Iceland | Piton de la Fournaise,…
While the largest volcano on Earth — Mauna Loa is not erupting, rates of deformation and seismicity at the summit remain slightly elevated and above long-term background levels. Other Mauna Loa monitoring data streams show no significant change in deformation rates…
Hawaiian Kilauea volcano continues erupting since December 20, 2021, with lava activity confined to the Halemaʻumaʻu crater. On April 15, the lava lake was 227 m (745 feet) deep and remains stagnant over its eastern half. SO2 emission rates remain elevated at 950…
The Alaska Volcano Observatory (AVO) has raised the Aviation Color Code to Red and the Alert Level to Warning for Semisopochnoi volcano on Friday, April 16, 2021, after sustained ash emissions rose up to 6 km (20 000 feet) a.s.l. Satellite data suggest ash emissions…
New activity/unrest was reported for 7 volcanoes from April 7 to 13, 2021. During the same period, ongoing activity was reported for 11 volcanoes. New activity/unrest: Karymsky, Eastern Kamchatka (Russia) | Krysuvik-Trolladyngja, Iceland | Pacaya, Guatemala | Piton…
Scientists at NASA’s Jet Propulsion Laboratory (JPL) and the University of Alaska (UA) have developed a new method that may lead to earlier predictions of volcanic eruptions. There are telltale warning signs that a volcano is likely to erupt in the future,…
In 24 hours to 00:00 UTC on April 14, the Taal Volcano Network recorded 383 volcanic earthquakes, including 238 episodes of volcanic tremor with durations of 1 to 12 minutes, 143 low-frequency volcanic earthquakes, and low-level background tremor that started at…
A new high-level, major eruption took place at Soufriere St. Vincent volcano at 10:40 UTC on April 13, 2021. The SO2 emissions produced over the past 2 days are now spreading over two continents — South America and Africa. Extremely heavy ash is covering the island…
