Which one of the following is a geological disaster?a.Storm surgeb.Wild firec.Tsunamid.Flood

To identify which option is a geological disaster, let's analyze each choice:

1. Storm Surge: This is typically caused by severe weather events, particularly hurricanes. While it can lead to flooding, it is primarily a meteorological phenomenon rather than geological.

2. Wildfire: This primarily results from environmental conditions and human activities. Like storm surges, it is not classified as a geological disaster but rather as a natural disaster related to vegetation and climate.

3. Tsunami: This is a series of ocean waves caused by large disturbances, usually underwater earthquakes, volcanic eruptions, or landslides. Tsunamis are directly related to geological processes and are classified as geological disasters.

4. Flood: Flooding can result from various factors, including excessive rainfall, storm surges, and melting snow. While it can be catastrophic, it is more an event resulting from a combination of meteorological and hydrological factors rather than being exclusively geological.

Conclusion

Among the options provided, c. Tsunami is the only geological disaster, as it is directly linked to geological processes like tectonic activity.
