  1. The loudest sound in modern history was a volcano. 🌋 When Krakatoa erupted in 1883, the blast was heard 3,000 miles away in Mauritius — and the pressure wave circled the Earth 3.5 times. Sailors 40 miles away had their eardrums burst. Sound, at its most extreme, becomes a weapon.

  2. This volcano burns BLUE. 🔵 At Kawah Ijen in Indonesia, sulfuric gases escape from cracks in the crater and ignite on contact with air — up to 600°C — painting the night with electric-blue flames up to 5 metres high. It's one of only two places on Earth where this happens.
