A volcanic eruption has begun near Iceland’s capital following days of seismic activity, with travelers likely to be spared any disruption.

Lava is emerging from ruptures that are estimated to be about 200 meters (660 feet) long, the Met Office said.

The eruption “does not seem very powerful” but is generating smoke consisting mostly of steam, Benedikt Ofeigsson, a geophysicist at the site, said by phone.
