Hoffman was instrumental in creating Internews' emergency response capabilities for responding to humanitarian disasters and secured its initial funding. Specially trained journalists worked with surviving local media to provide life saving information during relief efforts in Aceh and Sri Lanka after the 2004 Indian Ocean tsunami, Haiti following the January 2010 earthquake, the Philippines in 2013 following Typhoon Haiyan among other humanitarian crisis. Other humanitarian interventions have established radio stations for refugee populations fleeing fighting from Darfur, Sudan, Somalia, Syria and other conflicts. In January 2010 Hoffman assisted the formation of CDAC (Communicating with Disaster Affected Communities), headquartered in London, that coordinates emergency media response actions of BBC Media Action, CARE, the UN and other humanitarian and media development organizations.
