Illustration depicting a fissure eruption in the Krafla field,Iceland,in September 1977. A fissure eruption is the exploitation of large cracks in the surface made by upswelling magma. With a large fissure,the magma may escape along its whole length,rather than at a single point. The eruption depicted here occured along a 2 kilometer fissure,releasing large quantities of fluid lava. The region around Krafla volcano contains many geothermal power stations,which gain their heat from subterranean volcanic processes | |
