An electron microscope image of ash particles that erupted from Alaska's Pavlof volcano, collected in Sand Point on the night of May 18, 2013 by resident Kathleen Harper. The ash is composed almost exclusively of juvenile vesicular glassy particles with few crystals, the longest measuring approximately 200 micrometers across.

Volcanic ash billows from Mount Sakurajima in Kagoshima, on the southern Japanese island of Kyushu, on August 18, 2013. Kyodo reported that the eruption was the 500th one this year at the 1,040-meter (3,410-foot) high mountain, which is one of Japan's most active volcanoes.

Sakura-jima volcano emitted a dense plume of ash over the Japanese island of Kyushu on November 23, 2013. Currently Japan's most active volcano, Sakura-jima explodes several hundred times each year. These eruptions are usually small, but the larger eruptions can generate ash plumes that rise 3,800 meters (12,000 feet) or more above the summit.

Pele's hair is abundant around Halema'uma'u Crater, and originates from the active, spattering lava lake. When the lava spatters into the air, some of it stretches into thin fibers, which quickly cool into amber strands of glass, and can be carried off by the wind. In certain areas there is a nearly continuous carpet of Pele's hair, which is highlighted in the afternoon sun. (USGS/Hawaiian Volcano Observatory) #
