...clear day, people in Costa Rica's capital of San José used to enjoy the view of the dormant, 11,260-ft. volcano Irazú, 16 miles to the northeast. But dormant volcanoes, like "unloaded" guns, can be full of nasty surprises. Last March a violent explosion deep inside Irazú threw up a shower of rocks, some weighing as much as two tons. A dark cloud of gritty ash spread across the sky, and soon drifted down to cover the pretty little Central American city with a layer of what looked like dirty snow...
...atmosphere to learn more about cosmic rays and magnetic phenomena that interrupt radio communications. In the past year, other experts have slogged thousands of miles to map the uncharted wasteland, dived deep below the ice to study the metabolism of seals. They have located the world's southernmost volcano, analyzed bacteria left by explorers 50 years ago (the tinned food and biscuits left by Captain Robert Scott's men in 1902 are still there today, perfectly edible), mined coal-proving that Antarctica once had a tropical climate...
Fear & Sex. "I see the mind of a five-year-old as a volcano with two vents, destructiveness and creativeness," writes Author Ashton-Warner. "To the extent that we widen the creative channel, we atrophy the destructive one." To achieve that requires an unconventional kind of teaching-not imposing education from the outside, thereby fostering frustration and aggressiveness, but inducing the child to reach out from inside himself...
...rolling hills of Santa Clara County, 60 miles southeast of San Francisco, a man-made volcano erupted. A brilliant flame spewed 200 ft. in the air, and a screaming roar rolled across the country, knocking birds to the ground and shaking a helicopter that hovered a mile away. The eruption was over in less than two minutes, but its reverberations would shake more than helicopters. This was the first test of United Aircraft Corp.'s big, new solid-fuel rocket engine, and it was completely successful. Partisans of solid fuel will cite it proudly in claiming for solids...
Glittering Pebble. A few diamonds have been found in other parts of the U.S., but they are considered freaks, probably carried long distances by rivers or glaciers. The Murfreesboro diggings-at best a poor relation of the 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...
