The Nevado del Ruiz eruption in 1985 was primarily caused by the interaction of tectonic plate movements beneath the Andes Mountains, leading to increased volcanic activity. The eruption was a result of the melting of ice and snow on the volcano's summit, which created lahars—destructive volcanic mudflows. These lahars devastated the nearby town of Armero, resulting in significant loss of life and property. The event highlighted the importance of monitoring volcanic activity to mitigate risks to surrounding communities.
