Fuse means, essential component is a metal wire or strip that melts when too much current flows, which breaks the circuit in which it is connected, thus protecting the circuit's other components from damage due to excessive current. I hope that helps.
Rift volcanoes occur where tectonic plates diverge, often on the ocean floor. These are generally less explosive. Hot spot volcanoes occur in the middle of plate boundaries where magma exits from weaknesses in the earth's surface. The Hawaiian Islands are an example of hot spot volcanoes. The most active area of volcanic activity occurs along the pacific plate boundary which is often referred to as the 'Pacific ring of fire'.
Hawaiian eruptions may occur along fissure vents, such as during the eruption of Mauna Loa Volcano in 1950, or at a central vent, such as during the 1959 eruption in KÄ«lauea Iki Crater, which created a lava fountain 580 meters (1,900 ft) high and formed a 38-meter cone named Pu Ê» u Pua Ê» i.ery little amounts of volcanic ash are produced. This type of eruption occurs most often at hotspot volcanoes such as KÄ«lauea and Iceland, though it can occur near subduction zones (e.g. Medicine Lake Volcano in California, United States) and rift zones.
