The absolute number of volcanoes that exists depends on your definition: active only, active, dormant plus extinct volcanoes? And even if we decide on a definition, nobody has really counted all of the volcanoes, especially the tens on thousands on the sea floor. The best guess is 1511 volcanoes have erupted in the last 10,000 years and should be considered active.

Maui does not have any active volcanoes like the Big Island of Hawaii. Mount Haleakala on Maui is a dormant volcano that has not erupted since the 1790’s.

Volcanoes that will never erupt again are considered extinct. Dormant volcanoes have not erupted in historic time (the last 200 years in Hawai'i) but probably will erupt again. Active volcanoes have erupted in historical time (the last 200 years in Hawai'i). Kohala, the oldest volcano on this island, last erupted about 60,000 years ago and is considered extinct. Hualalai erupted seven times in the last 2,100 years. The only historic eruptions were in 1800 and 1801.

No, and geologically there is no reason to expect one to appear. There is evidence, however, of multiple ash falls from ancient volcanoes preserved in rocks of Cambrian, Ordovician, and Devonian age in outcrops in eastern West Virginia and in the subsurface in the western part of the State, and in a flint clay in the Hernshaw coal bed of Middle Pennsylvanian age (Kanawha Formation) in southern West Virginia.

The turn off to the Mud Volcanoes is 38 km (check on GPS and include GPS map) short of Hingol River and is marked by a small blue sign (about 1 foot wide) saying “Sapt Post”. The color on the sign board will vary, but the road will take you straight to the coast guard camp at Sapt. Turn off the road at this sign towards the sea and follow the tracks. Here, a saying goes, “all tracks lead to Chandra Gupt.

Volcanoes are a natural way that the Earth and other planets have of cooling off. Planets are warm in their mantles. Heat inside planets escapes towards their surfaces. For reasons that are not well understood, heat sometimes melts rocks, which then rise buoyantly toward the planet's surface. When the hot rocks - called magma - and included gases break through the crust, an eruption occurs. The buildup of ash and lava flows around the eruption hole (or vent) makes a volcano.

Volcanoes erupt because of density and pressure. The lower density of the magma relative to the surrounding rocks causes it to rise (like air bubbles in syrup). It will rise to the surface or to a depth that is determined by the density of the magma and the weight of the rocks above it. As the magma rises, bubbles start to form from the gas dissolved in the magma. The gas bubbles exert tremendous pressure.

Alaska contains over 100 volcanoes and volcanic fields which have been active within the last one and a half million years. There are more then 70 potentially active volcanoes in Alaska. In the 1980's one morning of April 1st Sitka, Alaskans woke up to black smoke billowing out of the dormant volcano, Mt. Edgecombe; people were in a panic. The biggest joke had just been played on a whole town.

Most of the Earth's volcanoes are located around the Pacific Ocean because that is where most of the Earth's subduction zones. A subduction zone is a place where one plate of oceanic lithosphere (= the crust + uppermost mantle) is shoved under another plate. The down going plate eventually starts to melt, and the material rises up to erupt through the overlying plate. If the overlying plate is a continent, you get a chain of volcanoes such as the Andes or Cascades.

Shield volcanoes--the largest of all volcanoes on Earth (not counting flood basalt flows). The Hawaiian volcanoes are the most famous examples. These volcanoes are mostly made up of basalt, a type of lava that is very fluid when erupted. For this reason these volcanoes are not steep (you can't pile up a fluid that easily runs downhill).

The active ingredient is a homeopathic preparation of Silicea Compound, which is a combination of Silicea (Quartz), Atropa Belladonna and Argentum Nitricum. YES. The product is intended for the relief of symptoms from the flu, colds, sinusitis,tonsillitis, laryngitis, pharyngitis and otitis media, such as fever, sore throat, headaches, earaches and swollen glands. Some of these conditions may be bacterial, viral or a combination of both in origin.

The Active Directory is Microsoft's implementation of a 'Directory Service' and a directory service is basically something that stores data in an organized format and has the mechanisms needed to publish and access the data. Active Directory is not a Microsoft innovation, but rather an implementation of an existing model (X.500), an existing communication mechanism (LDAP) and an existing location technology (DNS), and each of these are covered in the FAQ.

JLD members become Active members after successfully completing the Provisional Course, or by transferring as a member in good standing from another Junior League. Active members have full voting privileges and are expected to meet all membership obligations as outlined in our Bylaws.

There's an old Hawaiian expression for an angry wife which translates something like this: "Pele is pouring lava on Puna again..." Well, Puna does take the brunt of her wrath, but there are other places that could be affected sometime in the future. Here's a lava flow hazard map: http://pubs.usgs.gov/gip/hazards/maps.html
