West Virginia’s Mount St. Helens volcano has resumed spewing ash and sulfur dioxide, and officials said Wednesday that no damage or evacuations have been ordered.

The Mount St.-Helens Volcano Observatory said it detected a small eruption from the crater on Monday afternoon.

It issued a tsunami warning for the area near the volcano’s summit on Tuesday afternoon, with a tsunami wave possible on Thursday morning.

The volcano has spewed ash and other toxic materials in recent weeks.

Mount St-Helens has been active since June 5, when a strong earthquake and powerful winds destroyed buildings on its slopes.

Authorities have warned people to stay away from the area.

The U.S. Geological Survey said it has measured ash and lava spewing from Mount St., but that the mountain is still not erupting.
