A volcano erupted again to the south of Iceland's capital on Tuesday, spewing lava and smoke in a fiery display of orange and red that triggered some evacuations, although air traffic continued as normal. Referred to as a land of ice and fire for its many glaciers and volcanoes, the North Atlantic island nation has now seen 11 eruptions south of Reykjavik since 2021, when dormant geological systems reactivated after some 800 years.
