http://boris.vulcanoetna.com or http://stromboli.net/boris A site dedicated to the volcanoes of Italy, their geology, activity and hazards with frequent updates on significant eruptive events - on-line since 8 May 1995 Last modified on 10 April 2003 Explosion at Stromboli, unrest at Etna The two active volcanoes of Sicily, Stromboli and Mount Etna, have returned into the news over the past few days. Stromboli, which had continued its effusive activity initiated at the end of December 2002, produced a powerful explosion on the morning of 5 April. Several buildings in the village of Ginostra were damaged by falling blocks; fortunately no one was injured. This explosion occurred at a time when residents and tourist operators on the island hoped for a resumption of tourism; at present it seems that no one (not even scientists) is allowed to climb on the volcano . Spectacular photographs have been posted at the INGV-Catania web site and at Stromboli On-line . At the same time, Mount Etna is showing signs of unrest. Ash emissions were observed on the morning of 7 April, and fumarolic activity at the summit craters has shown an increase in recent weeks.

Current Updates for US and Russian Volcanoes Alaska Cascade Range Hawai`i Long Valley area, California ... Weekly report of worldwide volcanic activity (this page is updated every 15 minutes) Alaskan Volcanoes Alaska Volcano Observatory Date: Fri, 11 Apr 2003 10:36:19 -0800 Hawaiian Volcanoes Hawaiian Volcano Observatory Kilauea Update Mauna Loa Current Activity 0825 April 11, 2003 Snow coats the summit of Mauna Loa on this beautiful Friday morning, but no other change is apparent on the volcano. A small blip on the tiltmeter record (see plot) on February 15 may have been related to the accumulation of snow during a storm the day before. It approximately coincides, however, with the start of renewed inflation of the summitwhich may be slackening off again. The network first showed definite lengthening of the line in late April or May 2002, after nearly 10 years of slight deflation, and this was confirmed by uplift measured by GPS and ground tilt measured by several dry tilt stations. The summit expansion tailed off and perhaps stopped in mid-winter, apparently resumed starting on about February 15, but now may be slowing again. We interpret the lengthening, uplift, and tilting to indicate resumed swelling of the magma reservoir within the volcano. Seismicity, however, remains low.

26. Vanuatu Map with detailed information on each volcano. http://volcano.und.nodak.edu/vwdocs/volc_images/australia/vanuatu/vanuatu.html

Vanuatu Vanuatu (formerly called the New Hebrides Islands) is a line of volcanic islands and submarine volcanoes 1,400 miles (2,300 km) east of northeast Australia. There are 13 main islands, nine of which are home to active volcanoes. Espiritu Santo and Malekula are older islands made of Miocene (5-24 million years old) andesitic volcanic rocks. Volcanic rocks on Maewo and Pentecost islands are also Miocene in age. Map with islands (names on left) and volcanoes (names to right of islands) from Fisher (1957). The geologically recent tectonic history of this region is complex. Colley and Warden suggested that the Miocene volcanic rocks were related to south-westward directed subduction. Present-day volcanism is related to the north-eastward directed subduction of the Australian Plate beneath the edge of the Pacific Plate. The two plates converge at a rate of about 9 cm/year. A divergent plate boundary (called a spreading center or spreading axis) is east of Vanuatu. Modified from Monzier and others (1997). Sources of information on the volcanoes of Vanuatu (New Hebrides Islands).

Click on the blue dot for more information about the park. (USGS photo) IN BRIEF Hawai'i Volcanoes National Park, established in 1916, displays the results of 70 million years of volcanism, migration, and evolution processes that thrust a bare land from the sea and clothed it with complex and unique ecosystems and a distinct human culture. The park encompasses diverse environments that range from sea level to the summit of the earth's most massive volcano, Mauna Loa at 13,677 feet. Kilauea, the world's most active volcano, offers scientists insights on the birth of the Hawaiian Islands and visitors views of dramatic volcanic landscapes. Over half of the park is designated wilderness and provides unusual hiking and camping opportunities. In recognition of its outstanding natural values, Hawai'i Volcanoes National Park has been honored as an International Biosphere Reserve and a World Heritage Site.

Mexico 1. Pinacate 2. Tres Virgenes 3. La Reforma 4. Barcena ... 22. Tacana Our NAFTA neighbors to the south have a large number of volcanoes. Most of them occur in a roughly east-west band that has been named the "Trans-Mexican Volcanic belt," but you can see that there are some outside this group as well. There are all kinds of volcanoes in Mexico. Most of them are pretty typical stratovolcanoes (the yellow triangles). There are also some large rhyolite caldera complexes (the pink circles). Finally, there are a number of monogenetic fields (the gray-lined pattern), within which there are many many small cinder cones maars tuff rings , small lava shields , etc. Some of the individual vents within the monogenetic fields are famous enough to have their own names (the orange triangles). The plate tectonic setting in Mexico is complex. In this map (which was adapted from maps drawn by other researchers), you can see that there is quite a complicated mixture of spreading ridges (red), transform faults (dark blue), and subduction trenches (light blue). Most of the volcanoes (6,7,9-11,13-22) are probably associated with the subduction of various small tectonic plates under the North American plate. Other volcanoes (2-5) are possibly associated with "leaky" transform faults, and the rest are unclear. You can click on any of the triangles or circles to find out more about that particular volcano.

38. Location Of Volcanoes Locations of volcanoes Imagine taking a world map, closing your eyesand putting your finger down on the map anywhere at random. http://www.cotf.edu/ete/modules/volcanoes/vlocation.html

Locations of Volcanoes Imagine taking a world map, closing your eyes and putting your finger down on the map anywhere at random. If you were instantly transported to that spot on Earth and were to look around, do you think you would be able to see a volcano? Or even more exciting, would you see an erupting volcano? Probably not, because most volcanoes, especially active ones, occur in only a few well-defined narrow bands across the face of Earthsomething like wild animals confined to reservations. Actually, at most locations on Earth, you would only see a lot of sea water (but that's another story!). But even if you picked a place on land, in most cases there would be no volcano nearby. That is probably just as well, because volcanoes, like wild animals, can be very dangerous and unpredictable neighbors. Sometimes volcanic eruptions are quiet outpourings of lava or playful displays of fire fountains that can safely be viewed from a reasonable distance . Other eruptions are so destructive that everything within a thousand miles can be annihilated within minutes. Why do most volcanoes occur in designated narrow bands? Why not everywhere, such as in your backyard? Why are some explosive and some not? For that matter, why do volcanoes occur at all? Reasonable understanding of the answers to these questions has only been attained during the last hundred years or so.
