A breakout started from the episode 61g vent on the east flank of Puʻu ʻŌʻō Monday morning (November 21) at around 08:40 a.m. The breakout sent lava flows south and northeast, and these flows were still active as of Wednesday night (Nov 23). This image, captured at 5:50 p.m. Wednesday (Nov 23), is from a webcam on Puʻu Halulu that looks southwest toward Puʻu ʻŌʻō (background). The light colored lava extending into the foreground is the more-active northeast branch of the breakout. This breakout poses no threat to nearby communities. Photo courtesy of USGS/HVO

Volcano Watch: Kilauea activity update for November 17, 2016

A USGS-HVO scientist collects Pele's hair from the parking area south of Halemaʻumaʻu Crater, which has been closed since early 2008 due to ongoing volcano hazards associated with the summit lava lake. Today, with the lack of trade winds, the noxious sulfur dioxide gas emitted from the lava lake was being blown away from this area, but his gas mask was at the ready just in case the wind shifted. A hard hat is necessary at all times because explosions within the summit vent, which occur without warning, have thrown pieces of molten lava and solid rock into this area and beyond.

Volcano Watch: Helicopter pilots and mechanics crucial for monitoring and observing active volcanoes

One of the most challenging environments for a small helicopter’s capability and a pilot’s skill is flying at high elevation (8,000 feet or more above sea level). Consider what it takes to land in the middle of a jagged lava flow or near the edge of a deep crater.
