The death toll is now 80.
Abandoned agricultural land may have contributed to the fires' severity:
“Wildland fires are not unusual in Hawaii, there are occasional fires every year. This year’s fires, however, are burning a greater area than usual, and the fire behaviour is extreme, with fast spread rates and large flames,” Dr Thomas Smith, an associate professor at the London School of Economics and Political Science said in a statement.
Dr Smith says the fire’s speed and intensity was driven by the land which contained plenty of dry and combustible vegetation.
“Land abandonment is a factor that played a role in the intensity and speed of the fire,” Dr Smith said.
“It’s clear from satellite imagery and from those who know the area well that the rural land to the east of Lahaina was once intensely managed plantations, with irrigation ditches and terracing. The agricultural land would have been fire resistant, with a very low fuel load (flammable vegetation) and higher fuel moisture due to the irrigation.”
“Since most of this land has been abandoned, long grasses, shrubs and young trees had taken root, substantially increasing the amount of flammable vegetation surrounding the town,” he added.
