The Cascade Range is pouring tons of carbon dioxide into the atmosphere, although another volcanic eruption like Mt. St. Helens is unlikely anytime soon, according to a new study. Large amounts of the greenhouse gas have been found in the cold springs that supply most of the rivers in the central Cascade Range, indicating a high level of underground volcanic activity under the long chain of mountains that stretches from California to Canada.

Scientists have found evidence of intense volcanic activity -- including tremors, pools of lava and plumes of smoke -- at two volcanoes near a major city in the eastern part of the Democratic Republic of Congo. The volcanoes in the central African nation could be about to erupt, threatening Goma, which has a population of more than half a million people, scientists said Thursday. "The eruption could be tomorrow, or the day after -- or at any other time," said Dieudonne Wafula, head of Goma's Volcanological Observatory.

For the last two weeks, a swarm of more than 10,000 small earthquakes, most of them tiny with with a magnitude of less than 1.0 but some reaching magnitude 3 or 4, have struck a remote desert area along U.S. 395, about 135 miles north of Los Angeles. The quakes near Coso Junction, east of the Southern Sierra in the Owens Valley, are in located in what is one of the two volcanic fields closest to Southland urban areas. But scientists with the U.S.

Little can top the drama of seeing an active volcano, and one Central American country -- Costa Rica -- has seven, including spectacular Arenal. A visit to Arenal is among the world's travel highlights. And both the trip and the stay are affordable and easily made. Arenal, a little more than nine miles from Fortuna in northwest Costa Rica, is a region of forested hills that contains the towering mountain peak that bears its name.

The Magellan spacecraft has sent back its first snapshots of Venus, revealing a planet ripped and shredded by powerful stresses that appear far more pervasive than the tectonic forces that generate great earthquakes and catastrophic volcanoes on Earth. The radar camera aboard the spacecraft, which pierces the layers of dense clouds that normally hide the surface of Venus, snapped a series of long, narrow images of the planet.

Picture a vast river of air 60 miles wide, a mile thick, 10 miles above the ground and moving at speeds as high as 200 m.p.h. Normally in the spring and summer, this river called the jet stream crashes across the northern Rockies and sweeps eastward through the Great Plains, bringing storms from the Pacific Ocean and drawing up other storms from as far away as the Gulf of Mexico to quench the thirsty agricultural fields of the Midwest. But not this year.

Much of the Earth's surface has been shaped by volcanic activity. Mt. Unzen, which erupted eight days ago in southwestern Japan, had been dormant for about 200 years before its recent activity. In 1792, the same volcano caused landslides and tidal waves that killed 15,000 people in Japan's worst volcanic disaster. It rumbled to life again late last year, with the eruption that began June 3 killing at least 38 people, including Harry Glicken, 33, of Los Angeles, a noted volcanologist.

The island of Hawaii grew out into the ocean as an eight-mile river of 2,000-degree lava from Kilauea Volcano poured into boiling salt water, shooting up clouds of steam. It was the first time lava has reached the ocean since 1972. Tom Wright, a geologist at the Hawaiian Volcano Observatory, said the flow was 650 feet wide at the shoreline and had "built out" 100 feet of new land. According to legend, the volcanic activity stops when the lava hits the sea, but Wright said no end was in sight.

New areas of dying trees have been found outside Mammoth Lakes, a probable result of more carbon dioxide gas emissions near Mammoth Mountain, according to Chris Farrar, the U.S. Geological Survey scientist in charge of volcanic monitoring in the area. The emissions, first verified last year, are being watched as a possible precursor of volcanic activity. At the same time, Farrar said, the total volume of the emissions, which had been estimated at 1,200 metric tons a day in recent months, seems to have declined.

The first high-resolution picture of Jupiter's moon Io, taken by the Galileo probe on an Oct. 10 fly-by, was released Friday by the Jet Propulsion Laboratory and NASA. The close-up picture of the moon, taken from a height of 417 miles, shows a lava field near the center of the erupting volcano Pillan. The resolution of the picture is 50 times better than that of the previous best pictures, taken in 1979 by the Voyager spacecraft.

The numbers of small earthquakes and emissions of carbon dioxide have increased at Mt. St. Helens in Washington state, slightly raising the chances that volcanic steam eruptions last seen in 1991 could resume, scientists report. The U.S. Geological Survey, in a statement issued last week, said its concern "will be heightened greatly" if the earthquakes move within 1 1/2 miles of the surface of the crater.

On the site of deep-sea volcanic vents that nurture some of the most exotic life forms ever discovered, scientists are reporting a likely eruption a mile below the surface of the Pacific, about 300 miles off the Oregon coast.

Massive volcanic eruptions in the Caribbean Basin 55 million years ago may have caused one of the most dramatic climate changes ever, according to researchers from the University of North Carolina. Through a chain of events, the eruptions caused the release of massive amounts of methane into the atmosphere, leading to global warming that could have speeded the evolution of countless new plant and animal species, they report today in the journal Geology.

Volcanic eruptions beneath Europe's largest glacier melted the cap of the icy mass, unleashing flood waters that swept away two bridges in Iceland. Flooding from the Vatnajokull glacier threatened a third bridge along the country's southern coast, said Orn Egilsson, spokesman for Iceland's civil defense agency. "The speed of the water is much more than people imagined," he said of the flooding in a remote area 185 miles east of Reykjavik, the capital.

In the first eyewitness accounts of the gas disaster in the Cameroon highlands, where 1,543 people were killed, survivors today told of seeing the ground covered with corpses and entire villages devoid of life. Worst hit was Nios village, where about 700 people lived beside the volcanic lake of the same name in this West African nation. Lake Nios' usually clear waters were bright red.

Since four magnitude 6 earthquakes occurred in a two-day period in the Long Valley caldera bordering Mammoth Mountain in the spring of 1980, there has been concern that future quake swarms might signal an eruption in this volcanically active region. For that reason, geologists have been monitoring the area carefully, checking both seismicity and ground deformation with an array of recording instruments. Since 1989, when a series of deep, long-period quakes rumbled beneath the 11,053-foot mountain itself, attention has refocused from the area east of Mammoth Lakes to the mountain west of town.
