Lava flows from the 1995 eruption of Cerro Negro traveled to the NNE, overtopping earlier flows from eruptions in 1923, 1947, and 1957. The 1995 flows traveled a maximum distance of more than 2 km from a new vent within the 1992 summit crater. The flows mostly were emplaced between November 22 and December 2. They covered an area of 0.65 km², and individual flow lobes had thicknesses of 2 to 10 meters.
