<p>Electric blue flames were spotted on road cracks near Leilani Estates subdivision on Tuesday, May 22, during the ongoing Kilauea volcano eruption.</p><p>US Geological Survey (USGS) released the video of the flames emerging from cracks on Kahukai Street in Leilani Estates, which was devastated by the volcano eruption in May. A USGS spokesman said the blue flames emerged after methane gas was produced from the volcano’s lava burning vegetation.</p><p>Methane gas is produced as a byproduct when hot lava buried plants and shrubs, which can then seep into cracks and create blue flames when it ignites, according to USGS</a>.
