<p>The US Geological Survey (USGS) said</a> the alert level for Kilauea volcano in Hawaii was lowered on August 18 as hazards from the lava flows and earthquakes caused by the crater collapses at the summit diminished.</p><p>However, the USGS said the change did not mean the eruption or summit collapses were over and it remained possible that activity could resume.</p><p>The USGS also shared drone footage of the fissure 8 cone on August 17, which showed the lava pond crusted over.</p><p>When sharing this footage, the USGS wrote, “The reddish-brown rock inside the cone is the result of oxidation; the interaction of heated rock and gases causes black basaltic cinders to change color, similar to rust forming on metal.” Credit: USGS via Storyful</p><br />
