This year was marked by numerous eruptions of volcanoes, with two topping the charts in terms of media attention and interest from the volcanologists: the Fagradalsfjall in Iceland and the Cumbre Vieja in La Palma, Spain.
As usual, Etna and Stromboli continued to erupt, but more unusual volcanic events happened as well.
Surface polygons and spiral coils in the Athabasca Valles prove this network of valleys near the Mars’ equator was forged by lava, according to a study published in Science on April 27.
