    Volcano: Mt. EREBUS

    Mt. Erebus continues its long standing eruption episodes. Situated within the small, inner crater on top of Mount Erebus is an openly convecting phonolitic lava lake. There were at least three well-defined openings at the bottom of the cauldron, and it was from these that the steam explosions proceeded."

    The Antarctica plate is mostly asesmic and moves little relative to other plates. About 95% of the edge of the plate is a divergent (spreading) plate boundary. Antarctic volcanoes are located along the margins of large rift systems. These rifts total 1,900 miles (3,200 km) in length, comparable to the East African Rift.

    Mount Erebus (elevation: 12,444 feet, 3,794 m) is on Ross Island in the Ross Sea. Erebus is an active volcano with a convecting lava lake, as discussed above, within a summit crater. It has been continuously active since 1972. Most eruptions are small and Strombolian in character, tossing bombs onto the crater rim. The volcano is less than one million years old.

    Merapi is a stratovolcano in central Java. Merapi has had 68 historic eruption since 1548. The current eruption began in 1987. Because of Merapi's violent past and its close proximity to Yogyakarta it was designated a Decade Volcano and is the target of increased research efforts.


    Volcano: SEMERU

    Semeru, a stratovolcano, has erupted at least 61 times since 1818. The eruptions are commonly moderate to moderately large and explosive. Some of the eruptions produced pyroclastic flows and/or lava flows. Ten of these eruptions have been fatal. Mudflows and secondary mudflows have been the most dangerous, killing nearly 600 people during the 1909 and 1981 eruptions.

    Sciliy - MOUNT ETNA

    Etna hoops it Up

    The "steam rings" are about 200m across

    April 1, 2000 - BBC

    Volcanoligists have witnessed dramatic rings of steam and gas being blown out of volcanic vents on the side of mighty Mount Etna in Sicily. Etna is the tallest and most active volcano in Europe, situated where the European and African geological plates are colliding.

    Dr Jug Alean and Dr Marco Fulle have been investigating Etna's growing level of activity and in February they saw the ejection of several spectacular hoops from the Bocca Nuova region of the mountain.

    It is difficult to gauge the size of what the scientists are calling "steam rings". They drift across the blue sky with no points of reference. However, the volcanoligists estimate the hoops to be about 200m across and up to 1000m above the ground.

    Such rings have never been seen in such detail before

    Smoke rings have been seen at volcanoes before but never in such detail. This time, there was hardly any ash on Etna and the gas billowing from vents had a high steam content. It is for this reason that Drs Alean and Fulle are using the term "steam rings".

    The rings would last up to 10 minutes

    Looking like the hoops produced by smokers, the hoops can hang in the air for many minutes. Etna's rings have been seen to last as long as 10 minutes.

    How they are formed is a mystery that these pictures may help solve.

    Volcano: STROMBOLI

    Stromboli is one of the Aeolian Islands of Italy. The island is about 3 miles (2 km) in diameter and 2,900 feet (900 m) above sea level. It rises 10,000 feet (3,000 m) above the floor of the Tyrrhenian Sea. Stromboli is one of the most active volcanoes on Earth. It has been in nearly continuous eruption for about 2,000 years (some volcanologists suggest 5,000 years). Most of the present cone was well developed 15,000 years ago. Most eruptions at Stromboli consists of small gas explosions that hurl incandescent blobs of lava above the crater rim. Several explosions occur each hour. Larger eruptions and lava flows are less frequent. When this type of eruption is observed at other volcanoes it is often referred to as a Strombolian eruption.

    Mount VESUVIUS

    Mount Vesuvius - one of the most notorious and potentially lethal volcanoes on earth - broods over the crowded Bay of Naples. It is a mountain with a deadly past. In 79AD, it buried the Roman city of Pompeii after a violent eruption, killing all 20,000 inhabitants. Today, scientists wonder if the same fate awaits the two million people that now live in its shadow.

    At a site called The House of Chaste Lovers, archaeologist Antonio Varone sifts through new excavations in the buried city of Pompeii. On a wooden pallet, he displays a recently uncovered skeleton - a young woman whose skull had been sliced in half. Evidence here supports the theory that victims were not suffocated, but killed instantly in a poisonous, burning wind, blowing at over 200 miles per hour. Then, their lifeless bodies were buried under an avalanche of rock, mud and pumice.

    But what were the warning signs to the death of Pompeii? Seismologist Aldo Marturano has found evidence of precursor earthquake damage - evidence that is supported by historical records. Earthquakes were shaking the city of Pompeii beginning 15 years before the death of the city. And today, Naples is being shaken again. Because of the recent increase of seismic activity, Maturano predicts an eruption within 10 years, reveals Judith Bunting's timely film.

    But the standard methods used for predicting volcanic eruptions are still rife with problems. Measuring gas emissions, earthquakes and changes in surface features give scientists clues, but they can not pinpoint when the moment of eruption will occur. For these assurances, scientists are working to build new monitoring technologies which are only now becoming available.

    There is an evacuation plan for the populated regions surrounding the mountain - a plan that would require 20 days to empty the cities. But given all the uncertainties in forecasting eruptions, when should the plan be put in to action? Will Naples be vacated every time there is an increase in seismic activity? Sceptics believe not. They believe evacuation plans create a false sense of security.

    Volcano: MOUNT MARSILI

    Europe's largest underwater volcano is active according to the scientists who have been monitoring it for years, but until recently believed it to be dormant. There has never been an eruption of the volcano in recorded history. The Tyrrhenian Project, the national research group studying the volcano, reported its findings last November 27, 1999.

    Mt. Marsili, which rises 9,800 feet (3,000 meters) from the seabed in the Tyrrhenian Sea southwest of Naples, is capable of producing huge tidal waves along southern Italy if its activity ever does build to an eruption. According to the researchers, "Il Marsili'" is about 40 miles (65 km) long and 25 miles (40 km) wide. The experts said its tip was only 1,640 feet (500 metres) below the surface of the water.

    Michael Marani, the scientist heading up the study of the volcano, said, "Because the Tyrrhenian Sea is the youngest sea in the Mediterranean, it is still unstable and carries elevated risks that must be monitored and understood." He reported that evidence of enormous masses which had probably broken away from the main crater a long time ago were found on the volcanic edge and that a repeat of a similar collapse would result in massive earthquakes in the region.

    Volcano: TELICA

    On August 10th a mild explosive eruption occurred at Telica, yet another volcano in Nicaragua. Gas with a little ash rose hundreds of meters above the summit of the volcano. The activity was possibly phreatic, caused by heavy rain falls on the volcano in the preceding days. Telica last erupted (in a similar manner) in May-June 1999. Further information substantiates the fact that Telica volcano showed signs of volcanic activity. In the beginning of June, a series of freatic explosions occurred in the crater.

    Volcano: CERRO NEGRO

    August 1999 - Cerro erupted. The eruption column that rises kilometers above the crater, and three new eruptive vents on the eastern flank of the volcano that emit pyroclastics "and sometimes a little lava".

    Volcano Ol Doinyo Lengai is a volcano in the Eastern Rift Valley, North Tanzania. Its name means "Mountain of God" in the language of the Maasai people who inhabit this area. Ol Doinyo Lengai is of particular interest to geologists because it is the world's only active volcano that erupts natrocarbonatite lava. It is also the only active volcano in this part of the East African Rift Valley, though there are many older extinct volcanoes in this region. Oldoinyo Lengai rises about 2000 metres above the Rift Valley floor to a height of approximately 2886 metres.


    The 13,428-foot volcano, one of Cameroon's main tourist attractions, draws thousands of people every year for a race up its black, rocky slopes. It is the highest peak in West and Central Africa, and has erupted five times in the past century, the last time in 1982.

    Volcano: LEWOTOBUI

    Lewotobi is a stratovolcano with at least 20 historic eruptions between 1675 and 1991. Most eruptions are from the Lewotobi Lakilaki vent. Only two eruptions have been from the Lewotobi Perempuan vent. Most eruptions are explosive and moderate to moderate large in size. Eruptions in 1869 and 1907 caused a total of three fatalities.

    Volcano: SANGEANG API

    Karymsky, - 110 km NW of Petropavlovsk-Kamchatskii, is the most active volcano of eastern Kamchatka. The latest eruptive period began ~500 years ago; much of the cone is mantled by lava flows less than 200 years old. The volcano has produced explosive eruptions sending ash to over 10 km in episodes that have continued sporadically for days or weeks; short lava flows have also been common.

    Volcano: FA' AFAFINE

    Researchers from the Woods Hole Oceanographic Institution have discovered an active underwater volcano in the Samoa Islands. The 14,100-foot (4,300-meter) volcano is 2,000 feet (610 meters) from the Pacific Ocean's surface. Its crater is 1 mile (1.6 km) across and 1,300 feet (396 meters) deep. The volcano's dimensions put it in a similar league with Mt. Whitney in California in the United States -- which at 14,500 feet (4,420 meters) is the largest mountain in the continental United States.

    Dr. Stan Hart, a Woods Hole geochemist and chief scientist, discovered the volcano on the easternmost end of the Samoan Island chain. The volcano was named Fa'afafine, a Samoan word that loosely translated means "wolf in sheep's clothing."

    - Volcano LOPEVI

    Volcano Lopevi an -island - 6 km in diameter, 1.450 m high, and 3,500 m above the seafloor, is one of the most active of the Vanuatu archipelago. In 1960, following a significant plinian eruption from the NW flank, a series of pyroclastic flows, lava flows, strombolian activity, and fumarolic emissions were observed during one month. In 1963, over a period of several months, large quantities of flowing lava ans ash spread through about 1,000 ha in the NW part of the island.

    Following a long period of fumarolic activity ( since January 1999) characterized by sporadic emission of small ash plume above the summit crater, a new explosive activity has begun on August 2, 1999. These explosives eruptions were accompanied by ash ejection and produced ash columns that rose about 1000 m above the volcano.
