Volcano Watch: Kīlauea’s summit lava lake continues to be quietly remarkable
The ongoing eruption at the summit of Kīlauea hasn’t made the news recently, but that doesn’t mean the recent eruptive activity hasn’t been noteworthy. It’s just been operating quietly in the background, without much fanfare.
Volcano Watch — Kīlauea’s south flank: What’s shaking?
Kīlauea Volcano is erupting. Its USGS Volcano Alert level is at WATCH. Lava activity is confined to Halemaʻumaʻu with lava erupting from a vent on the northwest side of the crater.
Getting in the “Rift” Zone: Why & How They Erupt
The rift zones extend from Kīlauea Caldera and, like the summit region, are prone to volcanic activity. But why are the rift zones so active?
Interpreting Surface Deformation at Kīlauea
Interferometric Synthetic Aperture Radar calculates the difference between two radar images taken at different times but looking at the same place on Earth.
Seeing the Earth Shake On Your Screen
All seismic data are freely available to the public. How can you view these ground motion data? There are several ways.
New Eyes in the Sky for Monitoring Hawaiian Volcanoes
The 2018 eruption of Kīlauea Volcano presented an opportunity for the U.S. Geological Survey to adopt unmanned aerial systems to better monitor the eruption.
USGS to Survey Kīlauea Volcano From its Summit to Kumukahi
USGS Hawaiian Volcano Observatory scientists have wanted to resurvey Kīlauea Volcano’s ground surface to document changes brought about by the Puna eruption.
New Insights Gained From Kīlauea Volcano’s 2018 Summit Collapses
A year ago, USGS Hawaiian Volcano Observatory scientists and Island of Hawaiʻi residents were in the throes of an historically unprecedented series of events for Kīlauea.
What We’ve Learned From Kīlauea’s 2018 Lower East Rift Zone Eruption
May 3, 2019, marks the one-year anniversary of the start of Kīlauea Volcano’s 2018 lower East Rift Zone eruption.
What Caused—Or Did Not Cause—The 2018 Kīlauea Eruption?
When a major geologic event occurs, scientists who study such events and the people who are directly or indirectly impacted by it seek to understand its cause.
Survey Helps Finalize USGS Lava Thickness Map
The USGS Hawaiian Volcano Observatory released a preliminary map of lava flow thicknesses for Kīlauea Volcano’s 2018 lower East Rift Zone eruption.
Eruption Pause Creates Opportunity to Probe Volcanic Pollution
In contrast to last summer, Kῑlauea’s current lull in activity provides an excellent opportunity to study background air quality.
New Outcrops at Kīlauea Make Good Geology
A good field geologist is an opportunist. Outcrops provide a great understanding to some questions about what happened in the geologic past.
How is Lava Flow Thickness Measured and Why Does it Matter?
Eruption rate is probably the best measure of volcanic activity, and the first step in that calculation is to measure lava flow thickness and area.
