41. Volcanic Structures Of The Republic Of Costa Rica General discussion of volcanic activity in the country, followed by a list of major structures, with photos and descriptions. http://kostaryka.org/wulkany2489/

Volcanoes of Costa Rica i List of 122 volcanic structures of the country Main page Volcan Irazu ... Ksiêga goœci In Costa Rica there are 112 volcanic formations. They belong to so called Pacific Rim of Fire. Seven of them is considered as active ones. Their activity is connected with fertile soils, which cover the majority of Costa Rica territory. Their suddenly erruptions made in past years huge destructions. The highest Costa Rica`s volcanoe is Irazu, the most active is Arenal and Poas has the second widest crater in the world. (diameter 1,5 kilometres). In 1950`s, the terrains around each Costa Rican volcanoes were decided to be under protection. Many of them are within the national parks. Costa Rica major volcanic peaks are stratovolcanoes. The type of magma that fuels most Costa Rica volcanoes is thick, viscous, and so filled with gases that the erupting magma often blasts violently into the air. The most serious eruption was that of Irazu volcanoe in 1963. It erupted clouds of smoke and ash that kept shovering over San Jose and other parts for two years. People had been walking with handkerchief. From roofs on every day were being scraped layels of polders of even 13 centimetres thickness. Over 100 square kilometers of the surrounding land were devastated. The latest eruption in Costa Rica was of Arenal Volcanoe on August 24th, 2000. One person died and two were severly hurt. 600 residents have been evacuated. The active volcanoes of Costa Rica -Poás, Arenal, Rincón de la Vieja, Irazú, and Turrialba- are featured in a year 2002 calendar sponsored by the Volcanology and Seismology Observatory of Costa Rica. The calendar features photos taken by pilot and photographer Federico Chavarría.

Fee Information Detailed information about Hawai`i Volcanoes National Park Link to information about the current eruption News and Events 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.

This is a resource web for those who are interested in diverse background information about this important "Decade Volcano". It is meant to encourage interdisciplinary research on this unique outdoor laboratory, which offers great opportunity for those interested in working together to learn how to mitigate volcanic hazards worldwide. The example here will hopefully form a model for the development of a new edition of the Catalog of Active Volcanoes of the World, a project of IAVCEI. Fuego Volcano The Fuego resource web is directed toward international researchers who wish to plan research at Central America's historically most active volcano, with more than 60 historic eruptions. It is designed as part of a new edition of the Catalog of Active Volcanoes of the World, an initiative of IAVCEI (the International Association of Volcanology and Chemistry of the Earth's Interior). Cerro Quemado Volcano Cerro Quemado is an exogenous dome complex that last erupted in 1818. It's location at the edge of Quezaltenango, Guatemala's second largest city makes it a prime volcanic hazard, however, and the prehistoric record shows that Quezaltenango was the site of devastation 1200 years ago.

Volcano Watch: Mapping New Lava Volcano Facts Mount St. Helens Pele: The Volcano Goddess ... Water, Wind and Earth Game volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. When pressure builds up, eruptions occur. Gases and rock shoot up through the opening and spill over or fill the air with lava fragments. Eruptions can cause lateral blasts, lava flows, hot ash flows, mudslides, avalanches, falling ash and floods. Volcano eruptions have been known to knock down entire forests. An erupting volcano can trigger tsunamis, flashfloods, earthquakes, mudflows and rockfalls. ctive volcanoes in the U.S. are found mainly in Hawaii, Alaska, California, Oregon and Washington. The greatest chance of eruptions near areas where many people live is in Hawaii and Alaska. The danger area around a volcano covers about a 20-mile radius. In May 18, 1980, Mount St. Helens erupted in Washington state. It killed 58 people and caused more than $1 billion in property damage. resh volcanic ash, made of pulverized rock, can be harsh, acidic, gritty, glassy and smelly. The ash can cause damage to the lungs of older people, babies and people with respiratory problems.

Skip Navigation 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.

Almost all of Alaska's active volcanoes are in the Aleutian arc. This map shows the locations of the volcanoes. Many of the most active are labeled by name and with the date of their last major eruption. Major in this sense is not precisely defined, but generally means a large explosive eruption or emplacement of lava as domes or flows. Because of the imprecise way "major" is defined there is some room for argument about the years associated with some of the volcanoes. (89k JPEG).
