The threat of natural hazards has increased worldwide and is directly correlated with a growing population that is increasingly concentrated in urban centers, an expanding investment in economic and social infrastructure, and an accumulation of vulnerable critical industrial and civil installations. Saudi Arabia is no exception to these trends. Saudi society's awareness of these problems demands measures to reduce the risk of loss of life, property damage, and economic and social disruption.
Natural hazards are either short-lived or long-term, have local, regional or national impact, and occur either as isolated events or in various combinations. The more frequent geologically related hazards affecting the Kingdom are floods, rock falls and ground collapse; volcanic eruptions and damaging earthquakes are potential hazards but occur relatively infrequently. SGS programs in Geohazards focus not only on mapping events such as landslides, flooding, earthquakes, and volcanism in the past, but also on making predictions about the recurrences and likely effects of such phenomena in the future.
Geohazards are geological or hydrogeological processes or events that pose a threat to people, property or the environment.
Geohazards can be precipitated by natural or man-made processes.
- Ground subsidence
- Landslides and rockfalls
- Flash floods
