REYKJAVIK, Iceland — A long-dormant volcano on the Reykjanes Peninsula in southwestern Iceland flared to life Friday night, spilling lava down two sides in that area’s first volcanic eruption in nearly 800 years.

There had been signs of a possible eruption recently, with earthquakes occurring daily for the past three weeks. But volcanologists were still taken by surprise because the seismic activity had calmed down before the explosion.
