Long and short term aid organized especially from the Red Cross and the United States. Volcano —glacier interactions on composite cones and lahar 7 Mar generation: Sulfur dioxide reacted with water to form a hazy layer of aerosol particles made up of sulfuric acid droplets.
Lava-ice interaction on a large composite volcano: Observational evidence shows a clear pinatuubo between historic eruptions and subsequent years of cold climate conditions.
