The April 30, 1982, Kaluapele eruption was a short-lived summit event that lasted about 19 hours. Lava erupted from a 3,200-foot-long fissure northeast of Halemaʻumaʻu crater, producing low fountains 15–30 feet high, with bursts up to 160 feet.

USGS geologists gathered samples by hand from vents on the dome and crater floor. Additionally, sulfur dioxide gas was measured from a specially equipped airplane before, during, and after eruptions to determine "emission rates" for the volcano.

Photo 9 of 15: Community pool collapsing into sinkhole at. Pool was roughly Olympic-sized and was about half full at the time of collapse. Impressive sounds of the rebar and concrete snapping, then the rush of water. View to north across the sinkhole. (1:30 p.m)

Photo 10 of 15: Sinkhole chimney after pool collapse. View to south across the sinkholne. For a time after the pool collapse and introduction of the pool water into the sinkhole, there was a noticeable increase in slope movement, especially deeper in the sinkhole. The house and building parts broke up further and disappeared.

Photo 11 of 15: Intersection of South Denning Drive and West Comstock Ave. Sinkhole is edging close to Denning Drive. One block of Comstock Ave was swallowed. View to south on Denning Drive adjacent to the sinkhole.

Photo 12 of 15: Water level has risen and is now apparent in sinkhole since pool collapse and house swallowed. View to south across the sinkhole. The rising water level is likely a result of the debris plugging the conduit into the Floridan aquifer. Water level is rising to assume a position more consistent with that of the surficial aquifer. (3 p.m.)

This collection is a group of 15 images (digitized slides) showing the sinkhole that opened late in the evening of May 8, 1981 near the intersection of South Denning Drive and West Fairbanks Avenue, Winter Park, Florida, USA.

Mesquite Flat Sand Dunes, Death Valley National Park, May 1980.

South Fork of the Ogden River streamgage shelter in the fall of 1980. This streamgage has been monitoring water levels and flow since March 21, 1921, making it one of 25 centennial gauges in Utah.

This ship-deck-based photograph of Muir Glacier and Muir Inlet, Glacier Bay National Park and Preserve, St. Elias Mountains, Alaska, is taken towards the north-northwest and shows the nearly 50-m-high retreating tidewater terminus of the glacier with part of its face capped by a few angular séracs.
