Over 20 years passed, and the Cerro Negro volcano was at peace until one of the volcano's largest eruptions occurred on April 9, 1992. Volcanic activity lasted for a total of five days, with the main sub-plinian eruption (VEI 3) occurring over a two-day time period, producing an ash column that was roughly seven kilometers high. Over 20,000 people were immediately evacuated, mostly due to failed water systems until eruptions ceased on the 14th of April. This eruption caused several fatalities, and widespread damage to land and property after the tephra volume measured 2.6 x 107 m3. This large tephra volume produced approximately four centimeters of ash across most of León, resulting in many collapsed roofs and additional injuries and fatalities.
