Organizations that are actively seeking individuals with the requisite skills and experience who are willing to work on a voluntary basis without remuneration in communities that have been devastated by a major fire, flood, hurricane, earthquake, tornado, tsunami, volcanic eruption, landslide, mudslide, snowstorm, drought, famine, explosion or nuclear accident, the outbreak of civil unrest, or other large-scale emergency of natural or human origin that disrupts the community's normal functioning. Volunteers may offer their services prior to an emergency and wait to be called to provide assistance; or may make contact following the emergency if they recognize that their skills are needed.
