Which among the following natural hazards has relatively slow onset?
Droughts
To determine which of the given natural hazards has a relatively slow onset, we need to analyze the typical characteristics and onset speed of each hazard listed in the options.
- Volcanic Eruptions: These are generally sudden events and can have rapid onset once the conditions for eruption are met. Therefore, they are typically considered fast-onset hazards.
- Droughts: These develop over an extended period and are characterized by a prolonged absence of water such as rain. They can take months or even years to fully develop, making them a slow-onset hazard.
- Wildfires: These typically have a fast onset, especially when triggering factors like lightning or human activities are present. They can spread rapidly once they begin.
- Landslides: Often triggered by specific events such as heavy rainfall or earthquakes, landslides can occur very quickly once the underlying conditions are met, categorizing them as fast-onset hazards.
Based on the above analysis, droughts are the natural hazard among the options that have a relatively slow onset because they develop over a prolonged period of insufficient rainfall or water supply.
