Natural Disasters

Natural disasters are catastrophic events caused by nature, often related to weather. They include floods, blizzards, hurricanes, tornadoes, earthquakes, tsunamis, volcanic eruptions, avalanches, and wildfires. Each disaster has unique causes and effects, such as floods from heavy rain or hurricanes, and blizzards characterized by strong winds. Hurricanes and tornadoes are powerful storms with high wind speeds, while earthquakes and tsunamis result from tectonic activity. Volcanic eruptions release dangerous materials, and avalanches are rapid snow movements. Wildfires spread quickly, often unnoticed. Technology aids in predicting some disasters, allowing for better preparedness.
