On 5 May 1970 fissures opened on the SSW, W, and NNE flanks of Hekla. An eruption plume reached nearly 16 km high, and fountaining fed lava flows to the SW, WNW, and N. Two eruptive fissures were active on the NE flank, seen here with minor Strombolian activity; these produced lava flows that traveled 6 km N. The N-flank lava flow remained active until 5 July.
