COPENHAGEN, Nov 13 (Reuters) - Seismic activity in southwestern Iceland decreased in size and intensity on Monday, but the risk of a volcanic eruption remained significant, authorities said, after earthquakes and evidence of magma spreading underground in recent weeks. Thorvaldur Thordarson, professor in vulcanology at the University of Iceland, said most recent data indicated a smaller risk of an eruption in the area around the town of Grindavik. [1/5]A view of cracks, emerged on a road due to volcanic activity, near Grindavik, Iceland November 13, 2023. Volcanic activity in the area continued for six months that year, prompting thousands of Icelanders and tourists to visit the scene. In August 2022, a three-week eruption happened in the same area, followed by another in July of this year.
