A series of mudflows occurred in Southern California in early January 2018, particularly affecting areas northwest of Montecito in Santa Barbara County. The incident was responsible for 23 deaths,[4] although the body of one of the victims has never been found.[5] Approximately 163 people were hospitalized with various injuries, including four in critical condition.[6] The disaster occurred one month after a series of major wildfires. The conflagrations devastated steep slopes, which caused loss of vegetation and destabilization of the soil and greatly facilitated subsequent mudflows. The mudflows caused at least $177 million (2018 USD) in property damage,[2] and cost at least $7 million in emergency responses[2] and another $43 million (2018 USD) to clean up.[3]
