Petrology of Volcanic Products
During and after the eruption in Surtsey, Icelandic and foreign scientists conducted diverse geological research on the island. The petrology of tephra and lava, the mineralogy of primary and secondary minerals, the chemical composition of gases in magma, and erosion by the sea and wind are examples of geological research projects that have been carried out. Examples of geophysical research projects are seismological measurements, aerial geomagnetic measurements, gravity surveys, and GPS measurements. The following is a discussion of the research data collected primarily after the end of the eruption.
