Dramatic video shows bolts of lightning as a volcano spews ash up to nine miles into the air in the Philippines. The country has raised the alert level, meaning an "explosive eruption" could happen in the coming hours or days: cnn.it/35OKfBK | CNN

Volcanic eruptions are breathtaking—but with lightning, they become nature’s most electrifying spectacle! When a volcano erupts, it creates a plume, which is a mixture of hot volcanic ash, gas, and water vapour that is tightly packed together. As it ascends, tiny particles gain friction, which helps contribute to these lightning strikes. #EarthCapture at Volcán de Fuego, Guatemala by Danielle Herrera 📸 #volcano #lightning #naturephotography #science | BBC Earth
