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.

document.write(address) SEARCH DocCentre MainSite Volcanoes WHAT ARE VOLCANOES? The term VOLCANO signifies a mountain or hill with an opening or vent from which gaseous liquid or solid materials from the earth's interior are ejected. The term is also used for mountains, hills, or craters formed by the accumulation or removal of materials during past volcanic events even if no active vent is presently existing. WHAT IS A VOLCANIC ERUPTION? This is the process wherein volcanic materials such as lava, fragmented rocks or gases are emitted or ejected through a crater, vent or fissure on to the earth's surface to form new deposits. WHERE ARE VOLCANOES IN THE CARIBBEAN? The Caribbean has several volcanoes distributed all over the Region. Those that been recorded as having erupted are classified as active volcanoes. The others are classified as inactive. Presently, the most active is the Soufriere Hills Volcano in Montserrat EXPECTED HAZARDS There are several processes that occur on the slopes of the volcano that pose hazards to man and his environment. Most of the hazards are directly caused by volcanic eruptions.

VOLCANOES Volcanoes did not play an important role in the Scriptures. However, some scholars have theorized that some of the events documented in the Scriptures were due to the actions of volcanoes, usually catastrophic events, possibly the plagues in Egypt. They played a factor in forming the terrain since the Biblical territory of Bashan, the now famous Golan Heights, was formed by extinct volcanoes. But for our purposes we are interested in volcanoes for what they can possibly tell us about the age of the earth. Hawaii, beautiful vacation land, land of peace and harmony, yet each island was born of tremendous heat and violence. The long chain actually starts with Loihi seamount which is presently not visible since it is still approximately three thousand feet below sea level. It sprang to life again in 1996 and during the summer of 1996 the largest swarm of earthquakes ever recorded on ANY Hawaiian volcano shook Loihi seamount. The swarm began on 17 July 1996; to date, a total of over 5000 earthquakes have been recorded by the Hawaii Volcano Observatory (HVO) network. Does this mean that soon we will be seeing video clips on the TV news of a new island being born? Probably not, since many volcanologists propose that it will be thousands of years before Loihi becomes an island. Seabeam bathymetry images taken in 1997 show that where there had once been a 300 meter tall cone called Pele's Vents there was a new pit approximately 200 meters deep that has been named Pele's Pit.

A dark silhouette of volcano against the clean dawning skies does not imply a threat - it is usually a token of nice weather for the people of Kamchatka. It is still hard, however, living in such proximity to the volcanoes, to get used to the idea that they are just some geological objects. The silence alongside the volcanoes is of a special sort, the one that fills the soul with an incomprehensible combination of anxiety and peace. Everything looks strange and unusual; you are gazing around as if perceiving a scrutinizing glance of another universe: you feel scared and at the same time happy, for this scrutinizing glance makes you feel someone's unbound power spreading over you - perhaps that sole true power you want to surrender to: Which of Kamchatka's volcanoes is the most beautiful? There is not an unargued leader, but one can certainly name the first three - though, as it goes, there are few objective criteria to assess beauty - nevertherless, the three volcanoes are Kluchevskoy, Koryaksky and Kronotsky. All the three can be good candidates to symbolize volcanic Kamchatka due to their total assets. The feature of Kluchevskoy, its height, (the absolute heights of the volcanoes are 4,750m, 3,456m and 3,528m respectively), is not as significant as it looks as the first glance. The greatest Eurasian volcano has made nearly 5 kilometers of height due to the fact that it was formed on a specific geological "pedestal", a slope of ancient volcano while the actual height (a relative one) is 3,000m, i.e. less than the height of Koryaksky (3,300m) or Kronotsky (3,100).

Text with graphics Volcanoes destroy and volcanoes create. The catastrophic eruption of Mount St. Helens on May 18, 1980, made clear the awesome destructive power of a volcano. Yet, over a time span longer than human memory and record, volcanoes have played a key role in forming and modifying the planet upon which we live. More than 80 percent of the Earth's surfaceabove and below sea levelis of volcanic origin. Gaseous emissions from volcanic vents over hundreds of millions of years formed the Earth's earliest oceans and atmosphere, which supplied the ingredients vital to evolve and sustain life. Over geologic eons, countless volcanic eruptions have produced mountains, plateaus, and plains, which subsequent erosion and weathering have sculpted into majestic landscapes and formed fertile soils. Ironically, these volcanic soils and inviting terranes have attracted, and continue to attract, people to live on the flanks of volcanoes. Thus, as population density increases in regions of active or potentially active volcanoes, mankind must become increasingly aware of the hazards and learn not to "crowd" the volcanoes. People living in the shadow of volcanoes must live in harmony with them and expect, and should plan for, periodic violent unleashings of their pent-up energy. This booklet presents a generalized summary of the nature, workings, products, and hazards of the common types of volcanoes around the world, along with a brief introduction to the techniques of volcano monitoring and research.

The Earth's crust is a thin layer of solid rock forming an outer shell, which is a few dozen kilometres thick. (It's thickness is comparable to the skin on an apple). Under the crust is a deep layer of hot soft rock called the mantle, which gets as hot as 4500 deg C. Below that is the much hotter core of hot liquid iron and nickel, reaching temperatures of 6000 to 7000 deg C. When this molten rock can find a way to the surface through the crust, it erupts into the air as magma, forming a volcano. There are 1500 volcanoes worldwide; 500 of them are active. About 60 major volcanic eruptions occur every year; two or three are usually huge and violent ones. Before you can understand how volcanoes happen, you need to know about plate tectonics . The Earth's crust is actually a collection of solid pieces which are floating on the soft hot mantle below. (Picture an ice cream cone that has been dipped into chocolate sauce; the chocolate solidifies on the surface, but is easily broken into many pieces that can slide around on the surface of the ice cream). The crust pieces are floating on the mantle, and can move. There are about 12 large pieces, and all of the plates are moving relative to all the others. Deep in the center of the oceans, molten rock is escaping through huge fissures in the crust, right at the boundary of several plates. This upwelling of new material causes the plates making up the ocean floor to continually spread apart.
