Detailed explanation-1: -Hazard risks are increasing due to population growth, urbanisation, pressure on marginal land and changes to the natural environment.

Detailed explanation-2: -A physical event, such as a volcanic eruption, that does not affect human beings is a natural phenomenon but not a natural hazard.

Detailed explanation-3: -The different types of natural hazards include: Geophysical hazards (e.g., earthquakes, volcanic eruptions, and tsunamis). Hydrological hazards (e.g., floods). Meteorological hazards (e.g., cyclones and storms).

Detailed explanation-4: -An increase in the number of people vulnerable to the natural hazard (e.g. population growth & increased population density close to hazard-prone areas) An increase in the frequency and magnitude of the natural hazard. A decrease in the number of people capable of coping with the natural hazard. 23-Aug-2020
