The 2018 rift eruption and summit collapse of Kilauea Volcano
In 2018, Kīlauea Volcano experienced its largest lower East Rift Zone (LERZ) eruption and caldera collapse in at least 200 years. After collapse of the Pu'u 'Ō'ō vent on 30 April, magma propagated downrift. Eruptive fissures opened in the LERZ on 3 May, eventually extending ~6.8 km. A 4 May earthquake (M6.9) produced ~5 m of fault slip. Lava...

Volcano Watch - Tephra deposit names: out with the old, in with the new!
The caldera was a dynamic place during the 300-plus years just before written history began at Kīlauea (in 1823), and the newly defined subdivisions of the Keanakāko‘i Tephra help us understand this energetic and dangerous time better than did the previous terminology.
Volcano Watch - Creative engineering helps HVO monitor Mauna Loa Volcano
The USGS Hawaiian Volcano Observatory (HVO) has a long tradition of innovation when it comes to the tools that we use to monitor the status and activity of volcanoes.
Volcano Watch - Tracking the latest moves of Kīlauea and Mauna Loa
On the Island of Hawai‘i, deformation is measured primarily with three techniques: tiltmeters, GPS (Global Positioning System), and InSAR (Interferometric Synthetic Aperture Radar).
Volcano Watch - For Sutton, It's Been A Gas!
Hawaiian Volcano Observatory (HVO) staff, alumni and friends recently gathered to honor the long and fruitful career of Jeff Sutton, our recently retired colleague.
Volcano Watch - How'd you like to spend Christmas on Christmas Island?
If you ever do spend Christmas on that South Pacific island, make sure Santa knows where to land his canoe of presents for you, as there are actually two islands called "Christmas Island".
Volcano Watch - Radar Specialist joins Hawaiʻian Volcano Observatory Staff
We welcome to our staff at the U.S. Geological Survey's Hawaiʻian Volcano Observatory our newest volcano watcher, Dr. Michael Poland.
Volcano Watch - Kīlauea diary
Mauna Loa's recent indigestion has attracted a lot of attention, stealing the limelight from Kīlauea, which has been in nearly continuous eruption for almost 22 years. Let's see what Kīlauea has been up to for the past year or so.
Volcano Watch - Volcano unrest spurs increased monitoring in Alaska and HAWII
As we work to increase monitoring capabilities on our restless neighbor Mauna Loa Volcano, our colleagues at the Alaska Volcano Observatory (AVO) are working to achieve the same goal at Mount Spurr volcano with an added sense of urgency as they race against the approach of winter.
Volcano Watch - Tuning in to Mauna Loa
Kīlauea's ongoing east rift zone eruption continues, and lava enthusiasts are being treated with renewed opportunity to view the flows, subject to the advisories expressed by the National Park Service and the U. S. Geological Survey.
Volcano Watch - Lights! Camera! Disaster!: Mixing fact and fantasy in the movies
Colossal natural disasters have been fodder for Hollywood movies long enough that we can recognize the basic recipe. A pinch of fact, a fistful of myth and exaggeration, and a large dose of spectacular special effects add up to an entertaining, but often preposterous disaster movie.
Volcano Watch - Eruptions help cool interior of Earth—but there's a long way to go
People frequently ask, "What's with all these eruptions I hear about? Is volcanic activity increasing?" Indeed, a plot of reported eruptions over the last 200 years shows ever-increasing numbers, but it is very likely that this is due to increased interest and ease of worldwide communication rather than increased volcanic activity.
Volcano Watch - Viewing Hawai`i's lava safely - a reminder
The recent serious injury incurred by a visitor to the Mother's Day lava flow field prompted this article. Shortly after midnight on March 10, a tourist from France sustained first-, second- and third-degree burns when he fell onto the hot lava flow.
