The lava lake at the Halema’uma’u Crater of Kilauea volcano has finally overflowed–an event that has been anticipated for days. The lake of molten rock formed in 2010, and has been a source of fascination for both scientists and volcano lovers, who trek to the site in hopes of glimpsing the lake’s overflow. Last week, the crater had so many visitors that park officials encouraged people to visit between 9 pm and 5 am to avoid traffic jams.
Right now, you can’t get close to the lava lake. A visitor’s area overlooking the crater has been closed for a while due to volcanic hazards. Yesterday, a rockfall showed the world why those precautions were a good idea.
Rocks sliding down the crater’s side into the lava lake resulted in an explosion, splattering hot lava 280 feet into the air. Take a look through some of the photos above or watch the explosion in the video below.
If you’re interested in seeing more of the lava lake, you can check out the action for yourself at any of the Hawaiian Volcano Observatory’s webcams (one of which was hit by a glob of lava yesterday), or visit one of the outlooks a safe distance away. Just don’t bring a drone. Last weekend, a tourist at the park was tasered by a park ranger after piloting a toy UAV near the crater, since drones are banned throughout the national parks system.
