Project 659 - Seismic risk assessment in Africa

IGCP project meeting in 2019

The meeting will focus on the regional seismotectonics and related seismic zoning in Africa. A large part of the meeting will be dedicated to presentations on the effects of large earthquakes in Africa and to discussions on the damage distribution.

The training will be devoted to:

1. the seismotectonic characteristics of African earthquakes,

2. how hazard models may be developed and how other models can be inadapted to the african urban and economic developments, and

3. the feasibility of early warning systems and related mitigation measures against earthquake damage of some capital cities

Brief outline of the project

Seismotectonic studies are necessary for seismic hazard assessment and earthquake risk mitigation in Africa. Seismic risk is increasing sharply, due to rapid population growth and urbanization. Accurate seismic hazard and risk assessment at a regional scale requires the identification and characterization of major seismic sources. In this project, the preparation of thematic maps in seismotectonics, earthquake hazard and risk assessment including seismic scenarios for some of the major cities on the continent constitute an important objective necessary for the social and economic development of Africa. The activities to be developed in the project address the application of advanced methodologies for the seismic hazard evaluation and its impact on densely populated territories of Africa.

The SEISMOSHAF project primary objectives are

  • to update the database developed in the previous IGCP-601 project on the Seismotectonic Map of Africa, and
  • to improve regional seismotectonic maps for application in a multidisciplinary approach to the seismic hazard and risk assessments.

The project will also explore the feasibility of real-time seismic risk mitigation, such as Early Earthquake Warning Systems (EEWS) in selected pilot-sites. The transfer of knowledge and training is also an important aspect of the project, which will enable similar studies at local scale.

The co-leaders are from Tahiland, Myanmar, China, Japan and United States of America.
