The fire started at 2:26 P.M. on Wednesday, September 9, just east of Jackson, when a tree came into contact with a power line, and quickly grew to over 14,500 acres (59 km2) by that evening.[3] By Thursday, the fire had spread into Calaveras County and more than doubled in size over 32,000 acres (129 km2).[4] Officials stated that the fire was expanding in all directions and that efforts were being hampered by difficult topography.[4]
On September 16, the Calaveras County coroner announced that the bodies of two people had been found in the Mokelumne Hill and Mountain Ranch areas.[2]
On June 22, 2017, Sacramento Judge Allen Sumner ruled that because "...the Butte Fire was caused by a public improvement as deliberately designed and constructed by Pacific Gas and Electric Company," the company is liable for all property damages caused by the fire.[3]
On July 1, 2020, the PG&E Fire Victim Trust (FVT) was established as part of the reorganization plan[8] of the 2019 bankruptcy of PG&E to administer the claims of the wildfire victims.[9][10] Also on July 1, PG&E funded the Fire Victim Trust (FVT) with $5.4 billion in cash and 22.19% of stock in the reorganized PG&E, which covers most of the obligations of its settlement for the wildfire victims.[11][12][13] PG&E has two more payments totaling $1.35 billion in cash, scheduled to be paid in January 2021 and January 2022, to complete its obligations to the wildfire victims.[14]
