The Three Sisters rock formation in the Blue Mountains of Australia was shaped over millions of years through geological processes, including erosion and volcanic activity. Initially, the area was submerged under a shallow sea, where sediments accumulated and formed rock beds and shales. Volcanoes erupted, blasting through these layers and creating ridges and sharp shapes that eventually became the Three Sisters. Erosion by wind, rain, and rivers continued to sculpt the formations into their cur

Lava is once again flowing from Hawaii’s Kilauea volcano. New USGS footage shows glowing streams of molten rock breaking through the crater floor — the latest in a series of eruptions from one of the world’s most active volcanoes. Authorities say the eruption remains confined to Kilauea’s summit area, with no threat to nearby communities. Scientists continue to monitor gas emissions, seismic activity and lava output. Kilauea is one of the world's most active volcanoes and has been erupting inter
