Summary

Description
English: Kilauea Volcano

Lower East Rift Zone May 22, 2018

The blue burning flames of methane gas were observed in cracks on Kahukai Street, in the Leilani Estates Subdivision, on May 22, around 11:30 p.m., HST. The view is to the southeast.

When hot lava buries plants and shrubs, methane gas is produced as a byproduct of burning vegetation. Methane gas can seep into subsurface voids and explode when heated, or as shown in this image, emerge from cracks in the ground several feet away from the lava. When ignited, the methane produces a blue flame. Methane is the natural gas burned in homes for heat and cooking.
