Guatemala’s seismology and volcanology institute says the new flow of searing hot volcanic material down the southeastern slopes of the Volcano of Fire is expected to produce a “curtain” of ash that the wind will carry to the west and northwest.
The institute’s latest bulletin says the blowing ash could reach heights of about 20,000 feet above sea level. It warns civil aviation authorities to closely monitor and take precautions regarding air traffic.
The report of new flows comes shortly after the country’s disaster agency announced new evacuations Tuesday afternoon and pulled back rescuers, police, journalists and others from towns destroyed after Sunday’s volcanic eruption.
A short video posted by the agency showed a steady flow of traffic away from the volcano to the sound of a blaring alarm.
The volcanology institute says the volcano has been experiencing eight to 10 moderate explosions per hour Tuesday morning, though the scale of the activity is far lower than that of Sunday.
