Interactive multiple-choice quiz: Volcano Risks

Volcanoes are powerful geological features that present both significant hazards and unique opportunities. Areas like the Pacific Ring of Fire are known for intense volcanic and earthquake activity due to plate tectonics. Volcanic hazards include fast-moving, high-temperature pyroclastic flows, mudflows known as lahars, and glacial floods called jökulhlaups. Scientists monitor these risks using advanced tools like GPS, tiltmeters to measure ground deformation, and sensors to track earthquake swarms. Despite the dangers, volcanic activity is harnessed for geothermal energy in regions like Iceland and is responsible for the formation of island chains such as Hawaii through volcanic hot spots.
