40 years ago today, on November 13, 1985 (October 2, 1985 in the lunar calendar), a volcanic eruption in Colombia killed more than 25,000 people. The 12-year-old girl Omaya had been soaked in mudslides for 60 hours. She finally stopped breathing because she could not be rescued. This is the moment when a little girl was called by death: her hands were swollen, her eyes were dim, and she lost the brilliance of her life. At this moment, this most meaningful photo illustrates the situation: We have lived for many years in a world full of hunger, terror, war, death and natural disasters. The little girl struggled in the mudslide for 60 hours until rescuers rescued her. In front of everyone, she fought and was angry. Although she received treatment, she died. On November 13, 1985, the Nevado del Ruiz Volcano in Tolima Province, Colombia erupted twice. A large amount of magma and rocks had swallowed several towns around the volcano. This volcanic eruption was the most serious natural disaster in the history of Colombia. At least 25,000 people were killed, two towns were destroyed, and material losses were huge. Nevado del Ruiz Volcano is located more than 200 kilometers northwest of Bogotá, the capital of Colombia. On the afternoon of the 13th, the volcano erupted for the first time and erupted again in the evening. According to reports, after the volcanic eruption, due to the melting of snow on the top of the mountain, the water levels of several surrounding rivers soared and became flooded, causing serious losses to the lives and property of nearby residents. Among them, Amero town in Tolima province was the hardest hit. After the volcanic eruption, the town of 20,000 residents was buried seven to eight meters thick of magma, rocks and volcanic ash, and 80% of the residents are estimated to have died. When the volcano erupted... At 9 p.m. on November 13, pilot Severo was flying a DC-8 jet transport from Miami to Bogotá. The plane flew at an altitude of 24,000 feet. Soon, he accidentally witnessed the eruption of Mount Ruiz. "At first, a dark red light shot into the sky." "Then, a gray wave came over my head, and I couldn't see anything," he recalled. The cockpit of the aircraft was filled with smoke, steaming hot, and the smell of sulfur overflowed. The high temperature gray waves blackened the nose and turned the windows of the plane gray, so he could only rely on the instruments to fly. Severo didn't know at the time that he was flying over the 17,000-foot-high, long-dormant Mount Ruiz. Hours after the volcano erupted, 20,000 people died in pouring plaster flows, thousands of people were injured, homeless or orphaned. The town of Amero, with about 20,000 residents, effectively disappeared from the ground, and all people could see was a 7 to 15-foot-thick gray covering of the town. Western newspapers pointed out that this Mount Ruiz disaster was one of the most painful volcanic disasters in history. It can be compared with the eruption of Mount Vesuvius in 79 AD, which caused two cities including Pompeii. Destruction. During this volcanic eruption, the first words to the outside world were spoken by the thirty-four-year-old mayor of Rodrigues Amero. At that time, he was still calmly reporting on the development of the situation. Suddenly, he shouted: "Wait a minute, I think Amero Town is submerged." These were also his last words. 31-year-old survivor Acosta talked about the situation when the volcano erupted. At that time, he, his father and four brothers were sleeping when plaster suddenly fell on the five of them. Then they heard the sound of boulders hitting the house and walls, and the family quickly climbed up the roof from the second floor where they lived. But as they climbed up, the wall fell. They grabbed my father and dragged him to safety, but a few hours later, he vomited blood and died.
