Apr 28: Pu’u O’o Lava Lake

Pu’u O’o: What it looked like just before it collapsed. See also this USGS timelapse movie of Pu’u O’o’s crater lava lake from March 20-April 18, and a blog post with a few good flyover photos on April 29.

(Pu’u O’o is a large vent on Kilauea’s shoulder that’s been erupting since 1983. See USGS / HVO photo history of the Pu’u O’o eruption.)

Dec 2011: Lava from Pu’u O’o Entering Ocean

Video by Bryan Lowry of Lavapix.com in 2011.

See HVO’s photo history of Pu’u O’o from 1983 to the present.
