LONDON (AP) — Iceland's Meteorological Office says two earthquakes early Monday rocked the caldera of Katla, one of the country's largest volcanos. Its volcanos attracted international attention in April 2010, when ash from an eruption of its Eyjafjallajokull volcano grounded flights across Europe for days, disrupting travel for millions.
Numerous tremors rock the Katla volcano in Iceland prompting the government to raise the alarm level.
