In geology, hotspots (or hot spots) are volcanic locales thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle.[1] Examples include the Hawaii, Iceland, and Yellowstone hotspots. A hotspot's position on the Earth's surface is independent of tectonic plate boundaries, and so hotspots may create a chain of volcanoes as the plates move above them.

At any place where volcanism is not linked to a constructive or destructive plate margin, the concept of a hotspot has been used to explain its origin. A review article by Courtillot et al.[9] listing possible hotspots makes a distinction between primary hotspots coming from deep within the mantle and secondary hotspots derived from mantle plumes. The primary hotspots originate from the core/mantle boundary and create large volcanic provinces with linear tracks (Easter Island, Iceland, Hawaii, Afar, Louisville, Reunion, and Tristan confirmed; Galapagos, Kerguelen and Marquersas likely). The secondary hotspots originate at the upper/lower mantle boundary, and do not form large volcanic provinces, but island chains (Samoa, Tahiti, Cook, Pitcairn, Caroline, MacDonald confirmed, with up to 20 or so more possible). Other potential hotspots are the result of shallow mantle material surfacing in areas of lithospheric break-up caused by tension and are thus a very different type of volcanism.

Estimates for the number of hotspots postulated to be fed by mantle plumes have ranged from about 20 to several thousand, with most geologists considering a few tens to exist.[8] Hawaii, Runion, Yellowstone, Galpagos, and Iceland are some of the most active volcanic regions to which the hypothesis is applied. The plumes imaged to date vary widely in width and other characteristics, and are tilted, being not the simple, relatively narrow and purely thermal plumes many expected.[8] Only one, (Yellowstone) has as yet been consistently modelled and imaged from deep mantle to surface.[8]

Most hotspot volcanoes are basaltic (e.g., Hawaii, Tahiti). As a result, they are less explosive than subduction zone volcanoes, in which water is trapped under the overriding plate. Where hotspots occur in continental regions, basaltic magma rises through the continental crust, which melts to form rhyolites. These rhyolites can form violent eruptions.[10][11] For example, the Yellowstone Caldera was formed by some of the most powerful volcanic explosions in geologic history. However, when the rhyolite is completely erupted, it may be followed by eruptions of basaltic magma rising through the same lithospheric fissures (cracks in the lithosphere). An example of this activity is the Ilgachuz Range in British Columbia, which was created by an early complex series of trachyte and rhyolite eruptions, and late extrusion of a sequence of basaltic lava flows.[12]

The hotspot hypothesis is now closely linked to the mantle plume hypothesis.[13][8] The detailed compositional studies now possible on hotspot basalts have allowed linkage of samples over the wider areas often implicate in the later hypothesis,[14] and it's seismic imaging developments.[8]

The joint mantle plume/hotspot hypothesis originally envisaged the feeder structures to be fixed relative to one another, with the continents and seafloor drifting overhead. The hypothesis thus predicts that time-progressive chains of volcanoes are developed on the surface. Examples are Yellowstone, which lies at the end of a chain of extinct calderas, which become progressively older to the west. Another example is the Hawaiian archipelago, where islands become progressively older and more deeply eroded to the northwest.

Geologists have tried to use hotspot volcanic chains to track the movement of the Earth's tectonic plates. This effort has been vexed by the lack of very long chains, by the fact that many are not time-progressive (e.g. the Galpagos) and by the fact that hotspots do not appear to be fixed relative to one another (e.g. Hawaii and Iceland).[15] That mantle plumes are much more complex than orginally hypothesised and move independently of each other and plates is now used to explain such observations.[8]

hi guys, hoping you can help; I have a WN300RPv3 wifi range extender. What i am trying to do is connect the extender to my iphones personal hotspot so i can then connect a device via the patch lead out the bottom of the extender - in other words use the device to give a hardwired unit the internet from my phone. When i try to set the unit up i cant find the phones personal hotspot - am i doing something wrong? thanks for any help

If your hotspot has a WPS button you should be able to connect that way if not you will need to connect to the extender and go to www.mywifiext.net then do the setup and connect to the aircards wireless network.

I was successful connecting a PC with Windows 10 OS using a Ralink and Linksys AE6000 USB wireless adapter to the extender which was connected to the iPhone 5 with the cell phone data and mobile hotspot enabled giving the PC access to the internet. The speeds could not be tested accurately because I am in the country with poor cell phone service. My cell phone provider assures me they will be enabling a block of LTE towers. This exercise was preparation for cell phone service enhancements.

Hi, maybe it has become easier to connect devices to iPhone hotspots in August of 2019. I connect my PC through an iPhone hotspot using the lightning cable (USB). It is fast & sturdy and than on from the PC you can setup a (private) LAN network or a wireless network if you like. It needs (LAN) only a connected Router (PC LAN). These routers are cheap now to obtain. In Windows 10 it is possible to pause all syncing in the background because you use a SIM (metered connection). Your data (rate) usage will be considerebly lower. Expect speeds up to 30+Mbps. That seems sufficient even using Netflix in HD. I never use more then 2.5GB on a daily basis wich is within the 5GB daily standard limit of a unlimited 4G account. You do the math?

Iphones can't have cell data and wifi on at the same time. You must set up your iphone as a hotspot using cell data. Use another device to set up the range extender that can have the wifi turned on, like an ipad, or another iphone.

Please take care of your Hotspot Kit. Fees will apply if the Wi-Fi hotspot or any accessory is lost or damaged. Library card privileges will be suspended until the Hotspot Kit is returned or charges on the account are paid.

You can check the availability of hotspots at your local branch by searching "mobile hotspot" in the library catalog or by calling any branch. If hotspots are not available, you may place a Hotspot Kit on hold. Only one hold is allowed per library account. Once you are notified that your Hotspot Kit is available, you will have seven business days to pick it up at your selected library location.

In 1963, J. Tuzo Wilson, the Canadian geophysicist who discovered transformfaults, came up with an ingenious idea that became known as the "hotspot"theory. Wilson noted that in certain locations around the world, such asHawaii, volcanism has been active for very long periods of time. This couldonly happen, he reasoned, if relatively small, long-lasting, and exceptionallyhot regions -- called hotspots -- existed below the plates that wouldprovide localized sources of high heat energy (thermal plumes) tosustain volcanism. Specifically, Wilson hypothesized that the distinctivelinear shape of the Hawaiian Island-Emperor Seamounts chain resulted fromthe Pacific Plate moving over a deep, stationary hotspot in the mantle,located beneath the present-day position of the Island of Hawaii. Heat fromthis hotspot produced a persistent source of magma by partly melting theoverriding Pacific Plate. The magma, which is lighter than the surroundingsolid rock, then rises through the mantle and crust to erupt onto the seafloor,forming an active seamount. Over time, countless eruptions cause the seamountto grow until it finally emerges above sea level to form an island volcano.Wilson suggested that continuing plate movement eventually carries the islandbeyond the hotspot, cutting it off from the magma source, and volcanismceases. As one island volcano becomes extinct, another develops over thehotspot, and the cycle is repeated. This process of volcano growth and death,over many millions of years, has left a long trail of volcanic islands andseamounts across the Pacific Ocean floor.

According to Wilson's hotspot theory, the volcanoes of the Hawaiian chainshould get progressively older and become more eroded the farther they travelbeyond the hotspot. The oldest volcanic rocks on Kauai, the northwesternmostinhabited Hawaiian island, are about 5.5 million years old and are deeplyeroded. By comparison, on the "Big Island" of Hawaii -- southeasternmostin the chain and presumably still positioned over the hotspot -- the oldestexposed rocks are less than 0.7 million years old and new volcanic rockis continually being formed.

Although Hawaii is perhaps the best known hotspot, others are thought toexist beneath the oceans and continents. More than a hundred hotspots beneaththe Earth's crust have been active during the past 10 million years. Mostof these are located under plate interiors (for example, the African Plate),but some occur near diverging plate boundaries. Some are concentrated nearthe mid-oceanic ridge system, such as beneath Iceland, the Azores, and theGalapagos Islands. 006ab0faaa
