REYKJAVIK — The eruption of Iceland’s Eyjafjallajökull volcano has slowed with the lava flow completely stopping and only a “small amount of ash,” the University of Iceland said.

The eruption has declined a great deal, the university’s Institute of Earth Sciences said on its website in a joint statement with the Icelandic Met Office.

The ash plume from the volcano now reaches heights of 10,000 to 12,000 feet, blowing toward the northeast and then northwest, the university said. The findings are based on an inspection flight Friday, global positioning system data and other research, the statement said.

Particles spewed from the Eyjafjallajökull volcano last month grounded 100,000 flights and cost airline carriers $1.7 billion in lost sales, according to the International Air Transport Association.
