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 sq km, and individual flow lobes had thicknesses of 2 to 10 meters.
