Geological hazards — Insurance and legal and technical aspects

  • Arnould M. 
Symposium 113 Geological Hazards And The Environment

Summary

Geological hazards remain a major risk, even growing with urban concentration.

Scientific and technical progress is being made towards forecasting (probabilistic), prediciting (definite), prevention and warning, and protective works.

Legal measures are necessary for prevention. The international review is very confuse. This subject is in evolution mostly for land use planning and for building codes.

In addition, insurances exist against various geological hazards in several countries. A review is given with conclusions on geological and economical data necessary for a rational approach to the subject.

The geological data necessary for legal measures are the same.

Phénomenes Géodynamiques — Assurance Et Aspects Légaux Et Techniques

Résumé

Les phénomènes géologiques naturels, catastrophiques ou non, restent un risque majeur qui va même croissant avec les concentrations urbaines.

Les connaissances scientifiques et techniques progressent en vue de leur prévision (probabiliste), de leur prédiction (exacte), de leur prévention voire de travaux de protection.

Des mesures légales sont indispensables pour assurer la prévention. Le panorama international est très confus. Ce sujet est en pleine évolution tant pour l’occupation des sols que pour les codes de construction.

En complément, des assurances contre divers phénomènes géologiques existent selon des modalités variées dans différents pays. Une revue en est présentée. On en déduit les données géologiques et économiques qui sont nécessaires pour traiter rationnellement le sujet.

Les données géologiques nécessaires pour des mesures légales sont les mêmes.
