Daily Mail on Instagram: "Mount Etna, Europe’s most active volcano, erupted on Thursday sending lava flows down its slopes and lighting up the night sky over Sicily in dramatic red hues. The eruption began from a high-altitude vent earlier in the week and was accompanied by volcanic tremors as molten rock moved steadily downhill. Authorities issued a precautionary alert and increased monitoring in the area, warning of potential risks for hikers near the volcanic zone. #volcano #sicily #mountetna"
