This record includes 53 perimeters since 1984.\n\nOther named fires in this record include Midway (2006), Tesla (2005, partly in county), and Explosives (2009).\n\n53 mapped fire perimeters centred in the county since 1984\n\n39,756 acres inside those perimeters since 1984\n\n4.4% of the county's area, as a share of 3,672 km²\n\nCorral 2009 most recent large fire on record\n\nBefore 20002000s2010s2020s \n\nFire perimeters coloured by decade.

The same model shows 69.7% of the county in areas that can burn.\n\nThat model’s mean conditional flame length is 2.47 feet.\n\nAcross 178 sampled points in San Joaquin County, the score runs from 10.8 to 70.9 — two neighbouring parcels can sit in different tiers.
