As of Monday, lava had burnt down 117 homes, said Hawaii County spokesperson Janet Snyder.
On Friday, the count was at 87 homes. Officials had previously been updating the number of structures burnt because it was difficult to tell from aerial surveys which were homes or other buildings.
Snyder said from now on the county would provide counts of homes destroyed.
Officials were waiting for a count of how many homes were destroyed in an area called Kapoho.
