Ubicado al suroriente de Manizales, el nevado levantmaiento una altura de 5. Similar but less deadly incidents occurred in andconsisting of a small explosive eruption followed by a large lahar.
The volcano continues to pose a threat to the nearby towns and levamtamiento, and it is estimated that up topeople could be at risk from lahars. Satellite radar image of Nevado del Ruiz, with the deep Arenas crater visible near the summit. At lower elevations, the slopes become less steep; their inclination is about 10 degrees. Five domes ringing the summit plateau have emerged as the ice has retreated.
Spectacled bear Nevado del Ruiz is generally teodoligo forested because of its high elevation, and its forest cover decreases with increasing elevation. The volcano is home to 27 species of birds endemic to Colombia, with 14 of these species confined to the region around the volcano. The park is a popular tourist destination and contains several tourist shelters. The first eruptions of Nevado del Ruiz occurred about 1.
During the older period, which lasted from 0. Once again explosive summit calderas formed from 0. On the morning of March 12,Nevado del Ruiz erupted. A large amount of ash was ejected, which completely darkened the surrounding area.

In total, the eruption produced 0. The and eruptions were similar in many respects, including in the chemical composition of the erupted material. Beginning Novembergeologists observed an increasing level of seismic activity near Nevado del Ruiz. In the latter, hot magma came in contact with water, resulting in explosions as the water was almost instantly turned into steam. The most notable of these events was an ash ejection on September 11, The report proposed various simple preparedness electtonico to local authorities.
In Novembervolcanic activity once again increased  as magma neared the surface. Armero was located in the center of this photograph, taken late November After descending thousands of meters down the side of the volcano, the lahars were directed into all of the six river valleys leading from the volcano.
While in the river valleys, the lahars grew to almost 4 times their original volume. Only one quarter of its 28, inhabitants survived. The loss of life during the eruption was due partly to the fact that scientists did not know precisely when the eruption would occur, and the authorities would not take costly preventative measures without clear warnings of imminent danger.
Civil defense officials from four nearby towns tried to warn Armero the lahar was approaching in the hour or so before it reached Armero, but failed to make radio contact.
Scientists later looked back to the hours before the eruption and slectronico that several long-period earthquakes, which start out strong and then slowly die out, had occurred in the final hours before the eruption.
The volcano continues to pose a serious threat to nearby towns and villages.

Nevado del Ruiz as seen from ManizalesAs the Armero tragedy was exacerbated by the lack of early warnings,  unwise land use,  and the unpreparedness of nearby communities,  the government of Colombia created a special program Oficina Nacional para la Atencion de Desastresto prevent such incidents in the future. All Colombian cities were directed to promote prevention planning in order to mitigate the consequences of natural disasters,  and evacuations due to volcanic hazards have been carried out.
About 2, people living along five nearby rivers were evacuated when Nevado del Ruiz erupted again in
