Nevado del Ruiz

The most deaths in the 1985 Armero tragedy in Colombia were caused by a combination of the eruption of the Nevado del Ruiz volcano, which triggered a large mudslide known as a lahar, engulfing the town of Armero and surrounding areas. The lahar buried thousands of people and led to the majority of the fatalities.

The main benefits of the eruption of Nevado del Ruiz volcano in Colombia are:

1. Volcanic eruptions can enrich the soil with nutrients, making it more fertile for agriculture.
2. It can create geothermal energy sources for electricity generation.
3. Eruptions can contribute to scientific research and understanding of volcanic activity.

The volcano mountain called 'Nevado del Ruiz', or 'La Mesa del Herveo' is located at about 129 kilometers to the west of Bogota, the capital city of Colombia. It's an active volcano that had its last eruption in the year 2013 and has an elevation of 5,321 m or 17,457 ft.

There are five villages within 45 kilometers of the volcano, Nevado Del Ruiz, sometimes called Mount Ruiz, in Colombia.

* Villamaria * Manizales * Herveo * Villa Hermosa * El Libano. None of the villages are on a river or canyon from the volcano, so they were not affected by lahars. They were all affected by falling ash.

There is also a large town, Armero, 74 kilometers away on the Lagunillas River, where 23,000 people were killed by lahars, or volcanic mudflows from the November 1985 eruption. The town was destroyed.

After the 1985 eruption that caused widespread devastation in Colombia, recovery efforts for Nevado Del Ruiz focused on rebuilding infrastructure, improving disaster preparedness, and implementing early warning systems. Through international assistance and collaboration, communities around the volcano have developed evacuation plans and monitoring systems to mitigate the impact of future volcanic activity.

The Nevado del Ruiz volcano is located on a destructive plate boundary whereby the dense, oceanic Nazca plate is being subducted under the less dense, continental South American plate. The melted rock from the Oceanic plate rises to the surface, the pressure builds until the magma erupts from the volcano. It is a composite or strato volcano meaning it is made up of layers of solidified lava and pyroclasic material.

I don't know Stratovolcano

From all the research I've done I have figured out that it had something to do with the shifting of the tectonic plate it sits on but I'm afraid that's about as detailed as it gets :/

The Richter scale is applied to earthquakes, not volcanoes. The 1985 eruption was a VEI 3 on the Volcanic Explosivity Index.

The most destructive eruption of Nevado del Ruiz occurred on November 13, 1985. While relatively small, the eruption triggered mudflows that buried several towns. Worst hit was Armero, where 21,000 people died.

the nevado del ruiz volcano killed about 23000 people on November 13th.Only about 5000 out of the original 28000 people living in the nearby city of amero survived. The volcano also injured 5000 people.

It is impossible to predict when a volcano's next eruptiopn will be.

some lost their families and were scarred for life !! many injured and over 23000 died.

Yes It is Active.

some peeps were killed which was sad:'( then all their houses were damaged too so it was like man it's completely over for me innit. boooo hoooo! oh well;) anyways, eeem what was the question again? oh yeah. well that's all i can think of. hope this has helped. seeeyaaaa's peeeps!;) {xxxxxxxxxxxx}

The Nevado del Ruiz eruption of 1985 was one of the most destructive eruptions in history. Part of its aftermath was the largest lahar in geological history, bringing the fatality total to over 23,000 people.

Initially, the volcano began spewing large amounts of sulfur dioxide, which is extremely detrimental to humans. It causes violent coughing and wheezing shortly after being inhaled, and has a very strong, putrid smell. The main problem, however, was that sulfur dioxide can easily chemically react with various substances to form dangerous products, such as sulfuric acid.

The volcano then began to experience strong seismic activity, leading up to the eruption. After the eruption, the physical structure of the Nevado del Ruiz, (stratovolcano) led to the corroding of a nearby lake and the creation of a lahar. Measurments leading up to the eruption indicate that the pH level of the lake was around .2, meaning that the sulfur dioxide was already reacting with the lake water to form an acidic solution.

Lahars are syrupy in substance, in a liquid state while in motion and solid when stopped, very similar to concrete. The Nevado del Ruiz lahar became a worldwide phenomenon due to the death toll it created and the Omayra Sanchez incident.

it is a stratovolcano, if u are talking about its shape. basically, it is cone shaped. if this is not what u were talking about, then i am sorry...

Yes, Nevado del Ruiz is located in the Northern Hemisphere. It is a stratovolcano situated in the Andes mountain range in Colombia, South America. Specifically, it lies at a latitude of approximately 4.25° N, placing it well within the Northern Hemisphere.
