The Fuego volcano in Guatemala exploded on Tuesday, sending gas and molten rock down toward rescue workers and residents trying to recover from its eruption on Sunday, which left at least 72 people dead.
The eruption on Sunday was the volcano's biggest one in more than 40 years, Reuters reports, and hundreds of people remain missing. On Sunday, there was no warning that the volcano was about to erupt, but on Tuesday, an alarm went off, giving people more time to escape or take cover. Guatemala's national disaster agency has ordered additional mandatory evacuations near Fuego.
The volcano — one of 34 in the country — is about 30 miles away from Guatemala City, and has been erupting on and off for the last 16 years.
