Volcano Calbuco erupted on Wednesday in southern Chile, sending a plume of ash and smoke several miles up into the sky, local television images showed.
CNN Chile reports a Red Alert has been issued for the surrounding area and people were being asked to leave.
The AFP reports the evacuation order applies to everyone within about a 6-mile radius of the volcano.
The last time Calbuco erupted, according to CNN Chile, was 1961, with its last reported “activity” in 1996, when it apparently emitted gases and steam.
Chile’s Onemi emergency office says the eruption occurred about 1,000 km (625 miles) south of the capital Santiago near the tourist town of Puerto Varas.
About 1,500 people were being evacuated, authorities said.
“The eruption happened about half an hour ago. There are a lot of people out in the streets, many heading to the gas stations to fill up on gas,” Derek Way, a resident of Puerto Varas, told Reuters.
