New Video: Kīlauea Summit Eruption | Lava Returns to Halema‘uma‘u
October 11, 2017

This 24-minute USGS video recounts the eruptive history of Halema‘uma‘u and tells the story of

Kīlauea Volcano's current summit eruption, from its start in 2008 through today. It begins with a Hawaiian chant that expresses traditional observations of an active lava lake, and describes the formation and continued growth of the summit vent and lava lake. USGS-Hawaiian Volcano Observatory scientists share their insights on the eruption—how they monitor the lava lake, how and why the lake level rises and falls, why explosive events occur, the connection between Kīlauea's ongoing summit and East Rift Zone eruptions, and the impacts of the summit eruption on the Island of Hawai‘i and beyond.

The new video documentary is published as USGS General Interest Publication 182, and is available on the USGS Youtube channel.


Are you ready for Hawaiʻi's next big earthquake?
September 22, 2017

The probability of a destructive earthquake (magnitude-6.5 or higher) striking the Hawaiian Islands in the next 10 years is 50 percent. Are you ready for it?


We encourage you to participate in the Great Hawaii ShakeOut earthquake drill at 10:19 a.m., HST, on October 19, 2017.

This drill is a great opportunity to practice "Drop! Cover! Hold on!"—actions that will reduce injury during an earthquake.


"Earthquakes in Hawaii: What you need to know" is a slide show about Hawaii's long history of damaging earthquakes and what you can do to protect yourself and your family when the next one happens.

For more info on how to minimize the risk of injury during an earthquake, go to: "Recommended Earthquake Safety Actions in Hawaii."
