On the 4th local time, the geological department of Colombia issued a yellow warning, saying that the recent Luiz volcano in central Colombia has been active, and that the volcanic movement has caused many abnormal earthquakes in recent days.
Volcanic movement intensified on the evening of the 3rd, but it was still at a low level. The government reminds the local people to pay close attention to the early warning issued by the relevant departments and take precautions in a timely manner.
Mount Ruiz is about 5,300 meters above sea level, and the top of the mountain covers at least 200 square kilometers of glaciers.
The volcano erupted on November 13, 1985, and a large amount of magma and stones almost completely destroyed nearby towns, killing at least 23,000 people, injuring more than 5,000 people and leaving about 50,000 homeless.
In 2015, the volcano erupted a large amount of ash from another violent movement, causing the nearby city airport to suspend operations.
