A series of ferocious wildfires, which ignited on Tuesday night, has claimed 67 lives and left a trail of unprecedented destruction across the Hawaiian Islands.

While the exact origins of the fires are still under investigation, experts highlight a combination of factors that may have led to the ignition and rapid spread of the flames.

According to the U.S. Forest Service, a staggering 85% of wildfires in the country are caused by human activities, and 1% of fires are from natural causes.

The U.S. Drought Monitor issued a report highlighting abnormal dryness in parts of Hawaii, noting increased brush fires. The report also witnessed a surge in severe drought conditions in recent months and pointed out several factors behind the wildfire.

Lahaina, a historic resort city, currently lies in ruins. The U.S. Department of Health and Human Services Secretary has declared a public health emergency for the state of Hawaii.

The wildfires have become one of the worst natural disasters in Hawaii’s history.

While the Lahaina fire is now 85% under control, six fires rage across Maui and the Big Island. Maui County police shut down the roads leading to fire-hit Lahaina.
