...double eruption produced none of the spectacular lava displays that characterize such perennially active volcanoes as Hawaii's Kilauea. Instead, the superheated magma within Nevado del Ruiz began to melt the thick blanket of snow and ice that caps the top 2,000 ft. of the peak. Filthy water started to flow down the sides of the mountain. The trickle swiftly turned into a torrent of viscous mud, stones, ashes and debris with a crest of 15 ft. to 50 ft. The liquid avalanche, known as a lahar, was soon hurtling down the steep slopes at speeds...
...take place. It may be that the phenomena will be of minor intensity, but they will be equally dangerous." For one thing, he asserts, the large glaciers that surround the crater of Nevado del Ruiz have still not been warmed by the eruptions. If those rivers of ice should melt, they would create additional mud avalanches that would place rescuers in serious danger...
Christiansen and others suspect that magma is produced in the subduction zone, the border between the diving plate and the lower mantle. In that complicated layer, a variety of phenomena, including high temperatures, changes in pressure and the influx of water, may act to melt the already softened rock. Minerals and water then coalesce with the molten material into viscous, tear-shaped packets known as diapirs. Because they are more buoyant than surrounding rock, the diapirs percolate upward, like bubbles rising through honey, melting more rock as they go. Eventually they accumulate in pockets called magma chambers, located two miles...
...fated Titanic was built and from which it set off on its fatal maiden voyage in 1912. Duffy said she hoped the iceberg would be "a symbol of hope" for the province's divided community. Alas, like so many peace agreements before it, the work is bound to melt down...
...homes around the U.S. get out of sticky situations. French-made Silpat baking mats were the first such products available. Next came silicone potholders, followed by spatulas, whisks and colorful baking pans. The latest: silicone brushes, like the Sili, left, which, unlike nylon brushes, won't shed or melt at high temperatures and allow you to apply an even flow of butter or marinade...
