GEOLOGY

Detailed explanation-1: -Earthquakes are one of the most unpredictable and damaging disasters. The scientific community has yet to find a way to predict when an earthquake will occur with enough time to evacuate areas. Systems exist, but they can only give a few minutes warning to residents that a disaster is on its way.

Detailed explanation-2: -The uncertainty depends on the poor understanding of the phenomena that control the slope failures, and on the inherent complexity and chaotic nature of the landslides. This is similar to other natural hazards, including hurricanes, earthquakes, volcanic eruptions, floods, and droughts.

Detailed explanation-3: -Volcanic Eruptions Helens – produce more energy per second by far, and are considered the most conventionally “powerful”. The most powerful eruption in the last 500 million years is thought to be the one that formed La Garita Caldera, an extinct supervolcano located in Colorado.

Detailed explanation-4: -Yangtze River Flood (1931) Haitian Earthquake (2010) Typhoon Nina–Banqiao Dam Failure (1975) Tokyo-Yokohama Earthquake (1923) Kashmir Earthquake (2005) Great Galveston Storm (1900)
