Lava flowing around islands of older lava in a lava channel

Kīlauea Volcano — Lava Flowing Around Channel Islands

Lava flows around islands in the lava channel. The direction of flow is from the upper right to lower left. Field crews can make a rough calculation of velocity by timing large blocks as they pass between two landmarks that are a known distance apart.

routine inspection of a UAS system prior to a flight

Two U.S. Geological Survey Unmanned Aircraft Systems (UAS) pilots perform a routine inspection of a UAS system prior to a flight at the summit of Kīlauea Volcano in June 2018. The UAS for this particular flight was outfitted with a multi-gas sensor to identify any new degassing sources within the collapsing summit caldera. All UAS flights inside Hawai‘i Volcanoes National

A recent issue of Volcano Watch [https://volcanoes.usgs.gov/hvo/hvo_volcano_watch.html?vwid=1232] looked at what the level of the lava lake within Halema‘uma‘u can tell us about how Kīlauea works and the hazards it poses.

March 15, 2018

A little more than ten years ago, conditions around Kīlauea Volcano's summit were much different than today. The caldera floor was open to the public, and the air above it was normally clear. Halema‘uma‘u was an impressive sight, but peacefully in repose.

This study implements the first continuous, real-time operational routine for tracking lava lake surface motion, applying the technique to the persistent lava lake at the summit of Kīlauea Volcano.

March 8, 2018

To set the stage for next week's Volcano Watch about the upcoming anniversary of Kīlauea Volcano's current summit eruption, this week we revisit the history of past Halema‘uma‘u eruptions. We do so by reprising parts of a Volcano Watch article written in December 2008, soon after the ongoing Halema‘uma‘u lava lake reached a milestone as Kīlauea's longest summit eruption since 1924.

Most people likely know that the USGS Hawaiian Volcano Observatory (HVO) uses seismometers and Global Positioning System (GPS) receivers for monitoring volcanoes. However, fewer people may be aware of the full extent of our volcano-monitoring toolkit.

Today's Volcano Watch begins with a question: Can you guess when the next slow slip event will happen on Kīlauea Volcano's South Flank? As a hint, the last one was in October 2015, and before then, events occurred in May 2012, February 2010, and June 2007. If this seems like a pattern, you're right.

Why are HVO scientists talking so much about Mauna Loa?...
February 15, 2018

In recent weeks, the USGS Hawaiian Volcano Observatory (HVO) joined forces with several other agencies to talk about Mauna Loa at community events and other public meetings. Unfortunately, some information presented at these gatherings has been misinterpreted.

February 8, 2018

If you visit Hawai‘i Volcanoes National Park's Jaggar Museum Overlook when the wind is calm, you might be able to hear the sounds of gas bubbles bursting and lava splashing in the Halema‘uma‘u lava lake at the summit of Kīlauea. What you hear is only part of a rich chorus of sounds emitted from many processes near the surface of an active lava lake.

In November 2017, "Volcano Watch" entered its 27th year of publication. The long history of this column is, in large part, thanks to the U.S. Geological Survey's Hawaiian Volcano Observatory (HVO) scientists and affiliates who write the weekly articles, Hawaii newspapers and online news outlets that print and post the column, and you, the dedicated readers who peruse it each week.
