Tortoise trouble

ERUPTIONS of the Galdpagos volcano Cerro Azul have forced conservationists to speed the capture of 20 endangered giant tortoises for a captive breeding programme. Recently a helicopter was hired for two days to airlift some 11 tortoises from the island of Isabela, the largest in the Galdpagos archipelago. The remaining …

Full of treasure

Geologists have discovered huge deposits of gold, silver, copper and zinc in the Manus Basin, part of the Bismarck Sea to the northeast of Papua New Guinea. These minerals were found while they were studying the formation of metal ores on the seafloor. A team led by Ray Binns of …

Volcanic after effects

The sudden climate shift at the end of the Palaeocene era 55 million years ago might be a result of volcanic eruptions. According to Timothy Bralower at the University of North Carolina, Chapel Hill, USA, volcanic eruptions released sulphur into the stratosphere. These clouds of sulphate particles formed aerosols that …

Fire, brimstone and cooling

volcanoes eject large amounts of sulphur into the atmosphere when they erupt, and actually contribute significantly to global cooling. The eruption of Mount Pinatubo, Philippines, on June 15, 1991, discharged huge amounts of ash and other debris into the atmosphere, creating the largest stratospheric cloud of sulphur dioxide ( so …

Volcanic aftermath

volcanic eruptions in the Caribbean island of Montserrat not only affect its surroundings, but poses a serious threat to Edinburgh, the capital of Scotland. Scientists have found that whenever the disastrous tropical eruption takes place, Edinburgh suffers its worst winter storms. Alistair Dawson, an earth scientist at the Coventry University …

The truth about an ocean

Most people would have heard about the mythical disappearance of Atlantis. Even researchers believe that the ancient Iapetus Ocean never existed at all. However, Warren Huff, a geologist at the University of Cincinnati, USA, has found evidence of a narrow Iapetus Ocean from ancient volcanic ash beds. He says that …

Volcanic after effects

the Hawaiian volcano of Mauna Loa supports an extraordinary range of climates and ecosystems. Yet the slopes of the volcano are constantly being resurfaced by the red-hot lava that destroys everything in its path. After an eruption, the cooled lava quickly becomes a home for plants

Jovian heat

The hottest volcanoes of the solar system are situated on Io, a moon of Jupiter. Latest images of the volcanoes may help scientists to investigate Io's most active volcanoes, Prometheus . The volcano appears to have shuffled about 80 km across the moon's surface in the past two decades. Alfred …

Hot Spotting

a new method presented by Paul Wessel and Loren W Kroenke at a recent meeting of the American Geophysical Union offers a way to locate hot spots under the ocean more easily and precisely than ever before ( Scientific American, Vol 276, No 4). Described as hot-spotting, the technique depends …

Golden moments

Volcanic eruptions normally release molten lava, water vapour and hot gases. But the Galeras volcano in Colombia is one with a difference. It spits out gold dissolved in its dense mix of gases; this gold melts out as magma from crustal rocks hundreds of miles beneath the surface. Fraser Goff, …

Waiting for the mud

WHEN Mt Vesuvius erupted in Italy, the town of Pompeii vanished. All that was left behind were crusts of dried lava. For long, scientists have held that it is the run-off streams of lava from volcanic eruptions that kills thousands of people, sweeping away entire civilisations. But recent reports have …

Tests back fired?

THE French have never had it so bad. Roundly criticised for having gone ahead with the nuclear testing inspile of a barrage of criticisms from most countries, they are now being for blamed for the violent eruption of Mount Ruapehu in New Zealand. The eruption which started on September 25, …

The bigger bang

VOLCANOES could have played a central role in the series of extinction events throughout geologic history, conclude researchers. The study, coauthored by several American geologists, claims that a volcanic eruption that lasted a million years and flooded Siberia with a mile-deep lava may have killed 80 per sent of the …

MONTSERRAT

A sleeping giant is about to come to life at the British colony of Montserrat in Eastern Caribbean. Eruptions and emissions of ash from a volcano dormant for centuries have sent almost 1,000 people scurrying from their homes. Half of the 11,000 population at Montserrat only a section is likely …

Que sera sera

In 1930, Iddu, a major volcano, erupted on Stromboli island in Italy. In 1951, a film was shot on the devastation wrought on islanders. Shot by director Roberto Rosselini. the film turned out to be a disaster. Today, Stromboli, surrounded by the Mediterranean blue and with its incredibly beautiful beaches, …

Rugged robots

The early sci-fi image of robots taking over hazardous tasks so far done by human beings came a step closer to realisation with the success of NASA's (National Aeronautics and Space Administration) Dante 2 robot in exploring an active volcano in Alaska. Descending more than 180 metres into the crater, …

Underwater threat

The discovery of a dormant volcano in an undersea ridge flanking the Barren Islands in the Andamans has galvanised the forest and wildlife officials into preparing plans to study the impact on the archipelago's flora and fauna in case the volcano erupts. The existence of the volcano came to light …

Erupting with a vengeance

In late September, Vulcan and Tavurvur - 2 volcanoe near the port of Rabaul in Papua New Guinea, spewed out dense smoke and poisonous fumes, throwing the country into a panic, Suffocated residents were forced to flee the port, whid was covered with volcanic ash about a metre deep. The …

Simulating the big blow

SCIENTISTS are trying to simulate the generation of hot poisonous gases from the mouth of a volcano in order to minimise the vast destruction they cause. And some scientists posit that volcanic gases, particularly sulphur dioxide, can also help predict eruptions. The most ambitious and sophisticated model so far is …
