Volcanic eruptions

Volcanic eruptions can begin without warning, but they are usually preceded by earthquakes that can be detected by seismograph.  Eruptions can cause danger by lava flow and ash fall. The ash from a single eruption can fall throughout the country depending upon the weather. The falling ash can be unsafe because of poisonous gases and materials, and is hazardous to consume.  It especially poses a threat to animals. Clouds of ash can cause disturbances to air traffic.  If an eruption starts under a glacier, it can generate a sudden surge of water that can damage man-made structures.
