GSA brings together a multi-disciplinary team with expertise in geology, geophysics, geomorphology and geotechnical engineering with the ability to offer a complete Geo-hazard service covering identification, risk assessment, analysis, solution engineering and management.
The most probable geologic hazards that may take place in the Middle East region are associated with Earthquakes, Floods, Rock Fall, and Volcanic Eruptions.
Sudden release of energy; shaking can damage Infrastructures and break utility lines (electric, gas, water, sewer). Although earthquakes are unpredictable, Geo-scientists try to map which regions are especially at risk and try to quantify the likelihood of the occurrence of such events.
Seismology – the science of earthquakescovers a broad range of applications. It not only measures the natural events but also seismic monitoring stations can be used to detect, locate and identify man-made events.
The rapid provision of information on earthquakes, and the assessment of their damage potential, is of crucial significance for governmental and local authority agencies and organisations to enable them to implement the necessary emergency measures when required.
Seismologists assess on a daily basis, latest seismic events.
Seismological Measures for Hazard Mitigation:
Detail seismic sounding and geological investigation for fault systems along coastline. Establishment of National system for earthquake information and Tsunami warning. Education and training of earthquake and Tsunami hazard preparedness for the population and community, Calculation model for Tsunami propagation and inundation.
Strong Motion Monitoring:
Strong Motion monitoring is obtaining reliable seismic data in real-time. Large Structure, Civil Engineering and Research Consulting, Building Monitoring, Site Surveys and Analysis

Rainstorms and average rainfall on the nearby mountains of the coastal areas of Saudi Arabia are rare. However, they can generate flash floods that cause damage to properties and result in loss of life.
Measures for Hazards Mitigation:
Flood hazard assessment, mitigation, river bank and river bed erosion control, flood control programs for streams, rainwater management for parking lots, sediment trap design, and anti-flood programs for the preservation of wildlife.
Rock fall or Landslides are rock, earth, or debris flows on slopes due to gravity. The factors affecting Rock fall can be rainfall, earthquakes, or caused by human activities. They can occur in developed or undeveloped areas.
Landslides constitute a major risk for communities, infrastructure and the environment all over the world.
Rock Fall Hazard Mitigation and Early Warning:
Hence, the growing impact of slope instability risks on the society and the economic development calls for advanced and efficient monitoring methods, improved strategies for hazard mitigation and early warning systems can only be achieved by enhanced interdisciplinary research.
Explosive volcanic eruptions can erupt magma, send ashes to cloud and have severe climatic and environmental impacts.
Volcanic Hazard Mitigation
By monitoring the seismic and geological activity, warn people ahead of time about impending danger. Volcanologists can measure the size of an eruption in two ways, the eruption magnitude (measured by the volume or mass of magma erupted) and eruption intensity (measured by the rate of magma erupted). There are also various forms of satellites and imagery, which monitor the activity.
