  • The Undara Volcano erupted 0.19 m.y. ago and formed lava fields covering 1,500 km2 with a volume of approximately 23 km3. One of the flows extended 160 km on a gradient that averaged only 0.3°. This great length was a result of very high effusion rates, favourable topography and lava tube efficiency.The Undara lavas are rather uniform hawaiites. Lava temperatures are estimated to have been somewhat less than 1175–1220°C and viscosities greater than 10 to 30 Pa s.Long, apparently single lava… CONTINUE READING
