Other than the creation of the islands themselves, what kinds of information are you looking for?\n\nThere are the cultural effects on the Hawaiians:\nhttp://www.nps.gov/havo/history/people.htm\n\nThere's the creation and destruction that occurs:\nhttp://www.nps.gov/havo/visitor/lava.htm

Currently there are over five thousand active volcanoes underwater varying from ones larger than any on the surface to cones no larger than an automobile. The net reslut of this action is thermal heating of the oceans, at key positions, which in turn reaches the surfaceto be carried aloft into the atmosphere to become part of our surface weather pattern system. As the oceans are heated winds of a high velocity are created and driven over the land areas due to temperature differential. \n\nIn the Pacific Ocean there are ocean basins - volcanoes, of which there are estimated to be about 20,000 on the ocean bottoms of the world. Some of these form single mountains, and others join with other volcanoes to form ridges. The highest ones rise above the surface of the water as islands, which in many cases linear groups such as the Hawaiian Islands. \n\nIsland groups are simply the highest summits of ridges. The submerged part of the Hawaiian Islands is among the largest and longest of these volcanic ridges--more than 1,500 miles (2,400 kilometers) long. \n\nMany island groups of the Pacific are linear in form, with the largest and highest island of the group at one end and the lowest and smallest at the other. This feature is true of the Hawaiian Islands, explained as the result of intermittent movement of the tectonic plate over what is called a hot spot. \n\nMolten volcanic material is ejected from it and results in the formation of a large mass of material if the plate pauses for a sufficient length of time at the spot. In this way a volcanic island, or ridge, is built. The plate moves, and another part of it lies over the hot spot, receiving fresh volcanic material. Meanwhile the older material, if it has become an island, is subject to erosion and thus is worn down.

Afect in long, medium and short term.\n\nRecent studies shows that earthquakes increase plancton in that specifc area. It warm deep water and increase potenciality of fitoplancton. \n\nInfact is not Tectonic plates but its effects. \n\nOther obvious consequences are volcanoes and montains resultant by tectonic effetc (medium and long term). \n\nAll dorsals (tectonic) have some kind of new categpory of life. They live from minerals, heat and chemicals, entire new ecossitems that are being usedto explain how can be life out of earth. \n\nAt a more long term, you have continent division, creating this way complete new race by geographic isolation. \n\nModern and humans: Tsunamis (changing Human life) like that one last year and  Big one (Economic crisis and Human catastrophic event) - Saint Andreas.

I'd have to agree with Kidd - the largest major city at immediate risk from volcanic eruption would be Naples in Italy.  But similarly, those mentioned in Washington are also at risk from the Cascade volcanoes - not so much from eruption eject but from mudflows (lahars).  I'm sure there are some major cities in Indonesia that are near major volcanoes, and those cities are also at great risk, as are most Japaneese cities.

The islands of Hawaii all started as underwater volcanoes before they got tall enough to be above water. Another famous example is Surtsey (see reference).

heh... are you referring to ecological endangered hotspots or hot spots under plates that cause volcanic activity?\n\nThere are... way to many ecological hot spots particularly in tropical areas in South America, Africa and South Asia.\n\nAs for hot spots associated with plate tectonics, there are many I'm sure but the Hawaiian Island chain is probably the biggest and longest.  Yellowstone wouldn't be a hot spot really, it's pretty close to a plate boundary and it's activity I would think is left over from this.  Hot spots are unusual for continental plates.  It seems like many island chains could have been formed by similar hot spots under ocean plates though.

Yellowstone volcanics are a localized feature that has shot through the overlying crust.  This is determined largely through geochemestry and heatflow studies.  The Hawiaan Islands are formed as a result of a hotspot.  You can see that the overlying plate has been moving with respect to the hotspot because the islands formed one at a tine in a line, showing plate direction.\n\nMt St. Helens is the result of a process called subduction.  The oceanic Pacific plate is being shoved underneath the North American plate.  As that plate is pushed deeper and deeper, heat and pressure create a partial melt that can rise to the surface and create volcanoes.  Look at the Aleutian chain, those are also subduction volcanoes, only there you see oceanic crust shoved under oceanic crust

Yes, in fact the Pacific Ocean is surrounded by what is called The Ring of Fire, regions of intense volcanic and seismic activity. Earthquakes are generated by the collision of tectonic plates. This can cause fissure in the crust allowing the magma to rise to the surface where it collects in cavities and becomes the source for volcanoes.

Remember that big Volcano :-)\n\nJust Kidding I know Hawaiians respect the land.

A string of volcanoes is called a volcanic front or island arc volcanoes.

Volcanos tend to form at the points where tectonic plates meet.  One notable exception is Hawaii, which is formed over a hot spot in the middle of the pacific plate.

The Goddess of fiery explosions before Hawaiin legend was \n   named Lisai, and the word meant the most confused.  The \n   legend is long and odd, goes like this.  Lisai was the last of\n   a skilled people that lived in mauai, paddled to lanakai and\n   lost their ships, so they could not return.  They found that \n   a previous inhabitant something like the Easter Island giants\n   had destroyed much of the livestock domestics like aliens \n   or uncivilized might do.  So they built new ships and then an\n   angel appeared to Lisai's friend and told her to build a great\n   fire to signal that Peace came to the island.  For she told her\n   your coming here with such great numbers reassures this is\n   a blessed heavenly place and the giants are gone and their\n   spoils are ruined, they will not return and not desecrate again.\n   The fire was a tradition something like for 2000 years on a \n   very high ledge as if signalling for even more to come from \n   other islands.  Then to honor their effort the volcano was \n    named for them, because it appeared with another angel vision\n    and replaced them on their duties.

The Hawaiian Islands are volcanic in origin. Each island is made up of at least one primary volcano, although many islands are composites of more than one. The Big Island, for instance, is constructed of 5 major volcanoes: Kilauea, Mauna Loa, Mauna Kea, Hualalai and Kohala. Mauna Loa is the largest active volcano on Earth. Kilauea is presently one of the most productive volcanoes on Earth (in terms of how much lava it erupts each year). The primary volcanoes on each of the islands are known as a shield volcanoes, which are gently sloping mountains produced from a large number of generally very fluid lava flows. \n    Hawaiian volcanoes primarily erupt a type of rock known as basalt. When molten, basalt produces liquids of relatively high fluidity, compared to volcanoes that erupt more silica rich magma types such as andesite, dacite or rhyolite. The fluidity of molten basalt favors the formation of lava flows, which is why the Hawaiian volcanoes generally have gentle sloping sides. By contrast, lavas with higher silica content are more viscous and commonly produce either thicker, shorter lava flows, thick blocky deposits and/or thick beds of ash that fall from the sky following explosive eruptions. These other types of volcanoes (common outside of Hawaii) are typically steeper sided. \n    The Hawaiian volcanoes were produced by the Hawaiian hot spot, which is presently under the Big Island of Hawaii. The image below shows the islands of the Hawaiian chain and the intervening shallows, banks and reefs along a line from southeast to northwest. Note that the islands of Lanai and Kahoolawe are not shown because they would "overlap" with Molokai and Maui, respectively (see the map of the Islands on the Hawaiian Volcanoes page) In general, when you move along the island chain from southeast (Hawaii) to northwest, (Kure), the volcanoes become older and older.\n\nMore (with diagras) is available at the source
