| Title: | LAVA CREATES CORROSIVE STEAM CLOUD |
| Caption: | Volcanoes produce a wide range of hazards including toxic gases and corrosive clouds of steam. In this picture of lava from Hawai'i's Kilauea volcano vaporizes seawater at temperatures of over 1000°C (1800°F). Flowing from the end of a lava tube, the molten rock creates a cloud of steam mixed with corrosive hydrogen chloride gas before it cools in the Pacific Ocean.
