What type of volunteers are fraternity brothers participating in debris removal after a tornado?

Fraternity brothers participating in debris removal after a tornado are identified as unaffiliated volunteers. This designation refers to individuals who come together to assist in emergency situations without being part of an organized group or affiliated with a specific disaster response organization. Their motivation is typically driven by a sense of community responsibility or personal initiative rather than a formal partnership with dedicated emergency management agencies or charitable organizations.

Affiliated volunteers typically belong to recognized groups, such as Red Cross personnel, who have a formal association with an organization that provides disaster response. Unpaid volunteers, while also contributing without monetary compensation, do not necessarily meet the criteria of being unaffiliated, as they could be part of a group. Seasonal volunteers often engage in specified activities during certain times of the year but do not apply in this context where the emphasis is on immediate disaster response. Hence, the fraternity brothers' voluntary actions in debris removal exemplify the characteristics of unaffiliated volunteers as they respond to a community need without formal ties to an organization.
