Roberto Vargas was among many Nicaraguans who mobilized in San Francisco to form the Comité Cívico Nicaraguense (Nicaraguan Civic Committee) following the 6.2 magnitude 1972 Nicaragua earthquake. The committee set up donation centers in the San Francisco Mission to benefit those affected in the earthquake, however the ruling Nicaraguan party headed by Anastasio Somoza Debayle was criticized for not distributing the aid received.
