| Copahue on Sunday |
The Copahue volcano began registering high seismic activity and started throwing smoke nearly a mile into the air.
On Monday, seismic readings returned to normal and the plume dropped to only a couple hundred feet.
However, officials, on both sides of the border, kept alerts running, warning residents of possible evacuation.
Only about twenty-two hundred people live near the volcano, but officials want them ready, just in case.
The volcano last erupted in 1991 and showed a lot of activity in 2001.
