The Three Systems to Faults Present in the Nevado del Ruiz Volcano Region

In the NRV region, there are three fault systems, one of which is from NS in the longitudinal direction to NNE corresponding to the Andean zone. (...) The other two systems are horizontal and the directions are NW and E - W. (...) The faults of Palestine and St. Jeronimo belong to the first system, with obvious topographical features, slope breaks, and drainage path bias. The second fault system is represented by Villamaria Termales, Rio Claro, San Eugenio, Campoalegrito, Campoalegre, Neridas, San Ramon, it is very interesting because it relates to recent volcanic events and hot springs.

Omayra Sánchez Garcón (August 28, 1972 - November 16, 1985) was a 13 - year - old Colombian girl who was murdered in trimmer Almelo when the Nevadodeluis volcano erupted in 1985. Volcanic debris mixes with ice and huge volcanic landslides (volcanic landslides, landslides, landslides) flowed into the valley below the mountain, about 23,000 people died, Armero and the other 13 villages were destroyed. After Lahar tore down the house, Sanchez was nailed under the shards of the house, where it was trapped in the water for three days. When she calmed down and fell into pain, her dilemma was recorded. Her courage and dignity touched journalists and rescuers, and they made enormous efforts to comfort her. After 60 hours of struggle, she probably died of gangrene or hypothermia

On 13th November 1985 Columbia's lively volcano Nevado del Luis erupted, melted the glaciers, carried mud and mudslides to the village on that foundation. A 13-year-old Omayra Sánchez and her family trembled in her house, one of which was literally lost their Armero town and was called the torrent of Lahar. Sanchez was buried beneath the roof of her house and called the rescuer to rescue her from the mud. They tried it. But unaware of the workers, Sanchez 's feet were pinned under the brick doors and captured by the dead family. There was no way to save the life of Sanchez after the Nevado del Luis volcano in 1985.

On November 13, 1985, a small eruption of Nevado delu Luis volcano near the territory of Almelo created a huge volcanic ash (volcanic ash mixed with water). And it mixed with ice, filled the whole town and destroyed it. It is estimated that 25,000 people died in 13 other villages of Almero and Trima. This tragic sequel is known as the tragedy of Almero - the shadow of the most deadly fire in history. Before the volcanic eruption, Sanchez and her father Alvaro Enrique are at home and she is a collector of rice and sorghum, brother Alba Endera and her aunt Maria Adela Garcon, and her mother Maria Arraya I visited Bogotá on business trip. On the night of the earthquake, Sanchez and his family woke up when he heard the sound of the volcano for the first time, and worried about the volcanic ash of the volcanic eruption.
