AssistAlert: Lava Flows Cause Significant Disruption on Reykjanes peninsula For the third time since December of last year, the Reykjanes volcano system has experienced another significant eruption. https://ow.ly/h26w50QzIe3 #iceland #travelalert

UDGS Foundation U.S. Geological Survey (USGS) USGS, Florence Bascom Geoscience Center Land slide triggered after fugo volcano eruption on 8th Sept 24 Watch out the date 8th Sept 2024 ,is the date given for major (6+) quakes ,as well as Volcanic eruptions Time and again ,it is stated that ,as per my theory, the dates predicted for major quakes are also prone for Volcanic Eruptions. This is because, both Earthquakes and Volcanic eruptions occur due to tidal pull on Earthcrust and magma, crossing threshold limit Not only this the location of epicenter of quake as well as mouth of volcanic eruption follow my epicenter location hypothesis, which says,.. The epicenter of Earthquake will be at location where Either Sun or Moon are at Zenith or Nadir Or rising or setting

As a volcano roars to life, Sulfur dioxide is released when magma is near the surface. 🌋 Even during non-eruptive periods, numerous volcanoes release significant amounts of sulfur dioxide, ranging from hundreds to thousands of tons per day. If you've visited volcanic areas like Hawaii's Kīlauea or Yellowstone caldera, you might have encountered the distinctive rotten egg smell from hydrogen sulfide. #Volcano #Sulphur #SulphurDioxide

Four Eruptions in Four Months. With Each Eruption Getting More Powerful. Iceland may expect a historically significant natural disaster after a submerged volcano animated in Iceland's Reykjanes Peninsula.

Remember the catastrophic Taal Volcano eruption of 2020? It’s making its presence felt again, sending plumes of smoke into the air, raising concerns among residents. Meanwhile, Kanlaon Volcano in Negros is showing signs of activity, releasing volcanic gas. What lessons have the resilient people of Agoncillo, Batangas learned, and how can we stay vigilant and prepared for the next volcanic threat? Stay safe, stay alert!

Hawaiian Volcano Update: Kīlauea Quakes Slower, 100-year Explosive Eruption Anniversary, May 16, 2024 Kīlauea continued to quake over the last week, but at slower rates than the previous two weeks, while the volcano’s ground surface continued to show inflation, also at a slower rate. Earthquakes remain clustered in the south caldera and Upper East Rift Connector areas, continuing this month’s trend. There continues to be no increased hazard to people, with volcanic gas emissions still the main current threat to residents and visitors between eruptions. Gas measurements remain relatively low around 60 tonnes of SO2 per day, still of concern for sensitive individuals nearby. Maunaloa continues to recharge following its 2022 eruption, overall remaining quiet with few earthquakes and sustained slow inflation. As a special bonus this week to mark its 100-year anniversary, we show video releases and compile a slideshow of restored and colorized historic photographs of the famous Kīlauea explosive eruption of 1924. This is augmented by excerpts from this week’s After Dark in the Park at Hawaiʻi Volcanoes commemorating the centennial event, presented by USGS-HVO’s Ben Gaddis and Don Swanson. Swanson’s segment delves into the mechanisms for the explosions, with theory evolving from purely steam-driven to now include small amounts of fresh magma erupted in 1924, and comparing that sequence to 2018. Gaddis’s presentation recounts the human experience of the eruption, showing many of the same images for which we present colorized versions. As usual, we review the monitoring signals, imagery, and reports available courtesy of the USGS Hawaiian Volcano Observatory, annotating the presentation on screen as we go and discussing live viewer questions. #Kilauea #Kilauea2024 #Maunaloa https://lnkd.in/gi6P_pgc

Hawaiian Volcano Update: Kīlauea’s Short Southwest Rift Eruption, June 6, 2024 Kīlauea erupted for 8.5 hours on monday morning, June 3, 2024, leaving a small footprint of lava and extensive ground cracking. The new fissures closely aligned with those from the 1974 eruption, about 2.5 miles southwest of Halemaʻumaʻu above Kīlauea’s Southwest Rift Connector, following the trend of the Koaʻe Fault Zone. In the 3 days since, the series of 4 fissures has continued to glow and emit large volumes of volcanic gases, although decreasing with each passing day. Fully contained within a closed area of Hawaiʻi Volcanoes National Park, the eruption did not threaten any people or infrastructure, apart from gases which impacted much of the island with vog. Although lava erupted, its small volume (0.1 to 0.4 million cubic meters) and the propagation of large ground cracks within 500 meters of Maunaiki suggests that most of this event occurred underground, as a larger volume of magma presumably moved past the active vents as an intrusion farther downrift. However, the ground tremor that accompanied this subterranean movement has decreased substantially since the eruption, and the USGS Hawaiian Volcano Observatory reports that it is “unlikely that this eruption will restart.” While the summit of Kīlauea appears to have contracted during the eruption, suggesting a net outflow of magma, the ground tilt monitor in the South Caldera area that feeds the Southwest Rift Connector has resumed inflating, suggesting a rapid recharge into the tapped area of the magma reservoir. Much of the current sequence has its roots in the late January Southwest Rift intrusion, which seemingly opened downrift pathways and weaked the overlaying ground. The 2024 eruption progressed downrift without much seismicity at the time, which was instead focused near the summit, and lava emerged from the general area that had exhibited major ground cracking following the earlier intrusion. There is currently no increased hazard to people, with volcanic gas emissions still the main threat to residents and visitors between eruptions. Gas measurements are higher than usual, with the most recent reported value of 5500 tonnes of SO2 per day likely higher than today’s emissions but still well above background levels. Maunaloa continues to recharge following activity in 2022, remaining relatively quiet with few earthquakes and sustained slow inflation, in addition to occasional flank movement in response to events on neighboring Kīlauea.
