Pu’u ‘Ō’ō is a cinder and spatter cone in Kilauea’s east rift zone. It began erupting on January 3, 1983; a summary of its eruption can be found here. This image shows the cone just starting to form a collapse pit on its flank.

View southeast from Overlook Cabin looking over the Valley of Ten Thousand Smokes. The pyroclastic and ash deposits that fill the valley remain nearly vegetation-free more than 100 years after the 1912 Novarupta-Katmai eruption.

Cinder cones at the summit of Mauna Kea. Mauna Kea is a dormant shield volcano on the north end of Hawaii Island. Astronomical observatories in the foreground.

Ascending eruption cloud from Redoubt Volcano as viewed to the west from the Kenai Peninsula. The mushroom-shaped plume rose from avalanches of hot debris (pyroclastic flows) that cascaded down the north flank of the volcano. A smaller, white steam plume rises from the summit crater. 

For a behavioral study of Crossarchus obscurus, the long-nosed cusimanse, in Tiwai Island Wildlife Sanctuary, Sierra Leone, West Africa, fishing nets were the most successful method of capturing an entire group of these mongooses, compared to baited live-traps and thatch fences (which channeled animals into live traps, and which were moderately successful).
