Volcanoes
The document discusses ways for an individual to prepare for and assist with disasters caused by earthquakes, tsunamis, and volcanic eruptions. It also examines the relationship between the locations of volcanoes, earthquake epicenters, and mountain ranges based on plate tectonic theory. Specific recommendations include demonstrating preparedness techniques and contributing to government efforts to reduce damage from these natural hazards.
