The violent explosions caused by the meeting of lava and sea water meant that the island consisted of a loose pile of volcanic rock (scoria), which was eroded rapidly by North Atlantic storms during the winter.
Instead, lava fountains and flows became the main form of activity.
Effusive eruptions on the main island returned on 19 August 1966, with fresh lava flows giving it further resistance to erosion.
The total volume of lava emitted during the three-and-a-half-year eruption was about one cubic kilometre (0.24xc2xa0cuxc2xa0mi), and the island's highest point was 174 metres (571 feet) above sea level at that time.
Most of the remaining area is capped by hard lava flows, which are much more resistant to erosion.
In the spring of 1965,[19] the first vascular plant was found growing on the northern shore[20] of Surtsey, mosses became visible in 1967, and lichens were first found on the Surtsey lava in 1970.
