Fissure Eruption

This is a type of eruption in which magma flows from linear fissures. For example, the basalt in the Deccan Plateau in India formed from the flow of lava along lateral fissures on both sides. This eruption was mainly basaltic. Laki Volcano (Lakagigar) in Iceland is a typical example with a 25-km-long fissure and lava coverage of 565 km 2. This type of eruption can also cause volcaniclastic flows. For example, the Palaeogene and Neogene tuffs in Nevada, United States, cover 200,000 km 2 and are up to 2,500 m thick, and this tuff layer is also known as the volcaniclastic plateau (see the diagram of volcanic fissure-type eruption) (Fig. 7).
