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...
July 02, 2019
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...
November 09, 2018
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...
July 18, 2018
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....
July 02, 2018
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...
June 08, 2018
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...
June 06, 2018
A vigorous eruption of lava continues from Kilauea's lower East Rift Zone (LERZ) fissure system in the area of Leilani Estates and Lanipuna Gardens. Local videographers reported that lava entered the ocean at Kapoho Bay at about 08:30 UTC on June 4, 2018. A...
June 04, 2018
The intermittent eruption of lava in the Leilani Estates subdivision in the lower East Rift Zone of Kīlauea Volcano accompanied by toxic fumes and fountains up to 100 m (330 feet) high continues. A total of 11 fissures have emerged and 30 homes have been destroyed...
May 07, 2018
An eruption has begun in the Leilani Estates subdivision in the lower East Rift Zone of Kilauea Volcano shortly before 03:00 UTC on May 4, 2018. Lava was confirmed at the surface in the eastern end of the subdivision. Hawaii County Civil Defense is on the scene and...

A collapse of the Puʻu ʻŌʻō crater floor on Monday, May 1, 2018 on Kīlauea Volcano’s East Rift Zone has prompted increases in seismicity and deformation along a large section of the rift zone, with seismicity currently occurring as far east as Highway...
May 02, 2018
Since the end of February 2017, the Hawaii Volcano Observatory (HVO) seismic analysts have noted a slight uptick in the number of earthquakes near underwater Lō‘ihi volcano. The quakes appear to be clustered roughly 10 to 12 km (6 - 7 miles) below sea level...
