Week 4 Volcanic Activity

England has many volcanos both benign and active. The different rocks type spill and spew into each other creating even more corrosion. Intrusive rocks found in the UK are Gabbro, Diorite, Granodiorite, Granite. While the extrusive types are Basalt, Andesite, Dacite, Rhyolite. The intrusive rocks tend to be, "coarser grained than the extrusive rocks as they cool at a slower rate, giving the minerals a longer time period grow larger in size" (Ukvolc). The extrusive rock types found with thin intrusive bodies can be found in Scotland and are called dykes or sills.

Being informed and informing the public is the work of The London VAAC. It is an International Civil Aviation Organization (ICAO) designated centre, responsible for issuing advisories for volcanic eruptions originating in Iceland and the north-eastern corner of the North Atlantic. Keeping the public safe is their priority.
