Mount Pinatubo erupted violently in 1991, being the second largest eruption on the planet. Pinatubo can be very deadly as 500,000 people live in a 40km radius. Early warnings and evacuations saved around 5,000 people in 1991. The eruption was so violent it threw gasses, ash and steam into the upper atmosphere, this caused the global temperature to decrease half a degree for two years. The eruption was then followed by Typhoon Yunya, the heavy rainfall along with the volcanic ash created very deadly lahars and the final death toll was around 850.
