The USGS Hawaii Volcano Observatory (HVO) reported increased seismic activity at the submarine Lōʻihi volcano in Hawaii from May 11 to 12, 2020. More than 100 earthquakes were detected, but USGS noted that there is no indication that a submarine eruption has…
Earthquake and ground deformation rates at Mauna Loa Volcano have exceeded long term background levels over the past several months, forcing the Hawaiian Volcano Observatory to raise the Alert Level to Advisory and the Aviation Color Code to Yellow. All communities…
Activity at Hawaiian Mauna Loa volcano has risen to levels comparable to a higher period of activity between 2014 and 2017, HVO scientists said. The last eruption at the volcano took place in 1984. While there is no cause for alarm, those signs of higher activity…
While Kīlauea Volcano in Hawaii is not erupting at the moment and rates of seismicity, deformation, and gas release have not changed significantly over the past week, deformation signals are consistent with refilling of the middle East Rift Zone (ERZ) and hazards…
The lull in activity at Kīlauea Volcano continues. HVO lowered the Alert Level for ground-based hazards from WARNING to WATCH, on August 17, but the Aviation Color Code remains at Orange. The summit has been quiet since the last collapse event on August 2. This…
The current eruption at Kilauea is unprecedented in scope and size in the past 200 years, the Hawaiian Volcano Observatory deputy scientist-in-charge Steve Brantley said Tuesday, July 16, 2018. "What we are observing now is unprecedented in the past 200 years…
The eruption of Kilauea volcano in the lower East Rift Zone (LERZ) continues with no significant change. Fountains from the fissure 8 spatter cone, now about 55 m (180 feet) continue to supply lava to an open channel that travels about 13 km (8 miles) to the sea….
The number of homes destroyed by lava has reached 600 since Kilauea started erupting on May 3, 2018, marking its most destructive eruption in modern times and the most destructive in the United States since the 1980 eruption of Mount St. Helens. The number…
Nearly 200 homes were destroyed by lava over the past 48 hours, bringing the total number to nearly 300 since Kilauea begun erupting on May 3, 2018. "It is safe to say that hundreds of homes were lost," Janet Snyder, a spokeswoman for Hawaii County said…
