Photos taken 33 years ago by a photographer who died in the Mt. St. Helens eruption have been discovered and developed.

Reid Blackburn took the photographs in April 1980 during a flight over the simmering volcano. When he got back to The Columbian studio, Blackburn set that roll of film aside. It was never developed. On May 18, 1980 — about five weeks later — Blackburn died in the volcanic blast that obliterated the mountain peak.

Those unprocessed black-and-white images spent the next three decades coiled inside that film canister. The Columbian’s photo assistant Linda Lutes recently discovered the roll in a studio storage box, and it was finally developed.

Chile’s powerful Cerro Hudson volcano is threatening to erupt

Chile’s powerful Cerro Hudson volcano has come back to life and is threatening a major eruption.

Patagonians are worried. Many remember Mount Hudson’s catastrophic eruptions of 1971 and 1991. The latter eruption was one of the most violent registered eruptions in Chile, and lasted for five months. At its peak it turned day into night, making the banks of nearby Huemules, Cupquelan and Ibáñez Rivers collapse with ash. Many areas in the region are still covered with ash, pumice and other volcanic rocks. “These are the characteristics of this highly explosive volcano,” said Juan Cayupi, a volcanologist at the National Emergency Office.

Farmers flee as Indonesia’s Mount Tambora volcano rumbles

Farmers begin fleeing as Indonesia’s Mount Tambora volcano comes back alive.

Villagers like Hasanuddin Sanusi have heard since they were young how the mountain they call home once blew apart in the largest eruption ever recorded — an 1815 event widely forgotten outside their region — killing 90,000 people and blackening skies on the other side of the globe. . . . The April 1815 eruption of Tambora left a crater 7 miles (11 kilometers) wide and half a mile (1 kilometer) deep, spewing an estimated 400 million tons of sulfuric gases into the atmosphere and leading to “the year without summer” in the U.S. and Europe.
