Earthquakes Swarm in Hawaii Hundreds of small earthquakes that suggest that magma is on the move under the surface of the Kilauea volcano prompted the rare closure of most of Hawaii Volcanoes National Park. The earthquake swarm began Sunday (06/17) morning and produced more than 260 recorded quakes in 17 hours.

Their report on 28 October showed that mass of the deposits is several thousand tons, smaller than that of the 1996 eruption (roughly 12,000 tons). The ash consisted of rounded older (altered) rock-fragments (andesite), minerals and clay, without any fresh lava fragments indicating contribution of new magma. They concluded that the eruption was phreatic one as well as the 1996 eruption.

Compare with the tectonic map. Map courtesy of NASA and the Smithsonian Institution. The most productive volcanic systems on Earth are hidden under an average of 8,500 feet (2,600 m) of water. Beneath the oceans a global system of mid-ocean ridges produces an estimated 75% of the annual output of magma. An estimated 0.7 cubic miles (3 cubic kilometers) of lava is erupted. The magma and lava create the edges of new oceanic plates and supply heat and chemicals to some of the Earth's most unusual and rare ecosystems. If an estimate of 4,000 volcanoes per million square kilometers on the floor of the Pacific Ocean is extrapolated for all the oceans than there are more than a million submarine (underwater) volcanoes.

It contains approxmately 400 eruption points with the youngest site approximately 7500 years old. There are many excellent examples of eruption styles including shield, scoria and maar volcanoes.

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 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.

When this molten rock erupts onto the surface, it is called lava. Volcanoes erupt four basic types of magma: Basalt, Andesite, Dacite, and Rhyolite. The type of magma erupted determines how explosive the volcano will be. Magma erupts either as a non-explosive lava flow, or as an explosive eruption of ash and pumice. The type of lava is determined by the percentage of silica in the lava. Rhyolite contains the most silica, Basalt, the least. The higher the silica content, the stiffer the lava. The lower the silica content, the more fluid the lava. Basalt lava, which contains less than 58% silica, is very fluid. It moves along the ground in long streams, such as this Hawaii Read More Go to Site MTU Volcanoes Page Votes:0 Welcome to the MichiganTechnological University Volcanoes Page Sponsored by the Keweenaw VolcanoObservatory.

Most of the activity involves the explosive ejection or flowage of rock fragments and molten rock in various combinations of hot or cold, wet or dry, and fast or slow. Some hazards are more severe than others depending on the size and extent of the event taking place and whether people or property are in the way. And although most volcano hazards are triggered directly by an eruption, some occur when a volcano is quiet.

Myers | hydrology | ground deformation | seismicity | gas | remote sensing | Monitoring Strategy Volcano monitoring methods are designed to detect and measure changes in the state of a volcano caused by magma movement beneath the volcano. Rising magma typically will (1) trigger swarms of earthquakes and other types of seismic events; (2) cause swelling or subsidence of a volcano's summit or flanks; and (3) lead to the release of volcanic gases from the ground and vents. By monitoring these phenomena, scientists are sometimes able to anticipate an eruption days to weeks ahead of time and to detect remotely the occurrence of certain volcanic events like exp Read More Go to Site USU VOLCANO Votes:0 USU VOLCANO, SW Hokkaido (42o32'N, 140o51'E) (6/01/00) The eruption continued, though the activity level has declined. Eruption cloud of white color is emitted from craters in the Kompirayama and West-Nishiyama area. Small explosions that were being observed in the West-Nishiyama in the late-April, intermittently take place just above the craters in the Kompirayama area, and cinders (or mud?) were issued outside the craters. The cloud became darker frequently when ash was included, probably reflecting partial collapse of the vent wall. Main active craters in the both crater areas were enlarged up to a few hundred meters across, and have dry and funnel-shaped floors. The uplifting only in the West-Nishiyama still continued as small as 10 cm a day.

The current map divides the island into zones that areranked from 1 through 9 based on the probability of coverage by lava flows. Otherdirect hazards from eruptions, such as tephra fallout and ground cracking andsettling, are not specifically considered on this map; however, these hazardsalso tend to be greatest in the areas of highest hazard from lava flows.

A well-informed public will neitheroverreact to the hazards nor ignore them. The Mauna Loa eruption of 1984 fed a major lava flow that advancedtoward the city of Hilo.

YoungHawaiian volcanoes, such as Kilauea and Mauna Loa, have summit calderas. Acaldera is a crater several miles in diameter that forms as the result ofcollapse when magma drains from beneath the summit. (Magma is the term used formolten rock that is still beneath the earth's surface; it is called lava when itreaches the surface.) Summit eruptions of Kilauea and Mauna Loa occur within ornear their calderas. Flank eruptions usually take place along rift zones, whichare highly fractured zones of weakness within the volcano. Rift zones typicallyextend from the summit of a volcano toward the coastline and may continue formany miles under the sea.

During the first days, five craters were active along a 1300 m long fissure, striking EW along the caldera rim, in similar place as the 1983 and 1934 eruption sites.

Volcanoes are beneficial to humans living on or near them. They produce fertile soil, and provide valuable minerals, water reservoirs, geothermal resources, and scenic beauty. But volcanoes can be very dangerous. Where can a person go to be safe from an erupting volcano? What types of volcanic hazards might they face? These questions are difficult to answer because there are many types of volcanic eruptions which produce different types of volcanic hazards.

Its two most active volcanoes -- Mauna Loa and Kilauea -- erupt lava frequently enough to pose a serious hazard to property on many parts of the island. About 40 percent of Mauna Loa has been covered by lava in the past 1,000 years and over 90 percent of Kilauea's surface is covered by lava less than 1,100 years old.

However, volcanic features are not common. There are less than 20 named volcanoes on Mars, and only 5 of these are giant shields. Also, volcanism occurs mostly within three regions. Even the mare-like plains cluster near these regions. The main cluster of volcanoes and lavas is in Tharsis. A much smaller cluster of three volcanoes lies in Elysium.

Cinder cones C inder cones are the simplest type of volcano. They are built from particlesand blobs of congealed lava ejected from a single vent. As the gas-chargedlava is blown violently into the air, it breaks into small fragments thatsolidify and fall as cinders around the vent to form a circular oroval cone. Most cinder cones have a bowl-shaped crater at the summitand rarely rise more than a thousand feet or so above their surroundings.Cinder cones are numerous in western North America as well as throughoutother volcanic terrains of the world.
