Irazú's eruption is "dry," containing no molten lava. But the acrid, ashy smog has caused added suffering among those with respiratory ailments. The fallout extends over 250 square miles, including 97,000 acres of pasture for some of the prize dairy herds of Central America. Grazing land was smothered. Thousands of sick cattle had to be killed, and milk production has dropped to 35% of normal...
Puddle of Lava. The "Needle Reactor," as Adams calls it, will be placed in a shallow shaft before its nuclear reactor is allowed to go critical. Quickly the temperature will rise to about 1,100° C. (2,012° F.), which is hot enough to melt most rock. Because of the insulation around the midsection, most of the heat will flow downward; soon the lower point will be surrounded by a puddle of lava. The needle reactor will gradually drop into this plastic stuff, and the lava will close over it and solidify...
...that the pressure or temperature at a predetermined depth will release it. Freed from this ballast, the needle will be lighter than molten rock, and it will float instead of sinking. At last it will surface like a blowing whale, bringing with it samples of deep-down lava that have forced their way into depressions in its shell...
Acquisitive Urge. Pagliai lives like the fiscal prince that he is. His showplace home in suburban Mexico City is a white brick Georgian mansion, graced with 14 live-in servants and 50 imported Italian umbrella cypresses planted in holes blasted into lava rock. Besides collecting pesos, he acquires Dresden figurines, Chinese jade, Venetian glass and ancient Spanish books that he often pores over until 2 a.m. His house also shelters Mexico's most distinguished selection of wines (7,000 bottles) and its finest private art collection-El Greco, Botticelli, Van Dyck, Dali, Diego Rivera-as well as Pagliai...
...famous diamond "pipes"' of South Africa-are genuine. Ages ago, a volcano must have erupted in what is now Arkansas. Presumably that geologic hiccup eventually resulted in an impressive cone, but hundreds of millions of years of erosion wore it down. The only remnants were traces of the lava that once filled the volcano's vent. The lava was kimberlite, named after Kimberley, South Africa, and as it disintegrated, it released a few diamonds...
