Willis has clinched a massive contract from the Turkish government to provide catastrophe and financial modelling in the earthquake-prone country.

The broker and its project partners will develop and supply models for earthquake and flood risk for the whole of Turkey.

An economic model of Turkey will be built, showing the effects of catastrophes on the economy and government budget, and suggest ways of improving hazard mitigation policies.

The deal is part of a World Bank-funded project called the Turkish Emergency Flood and Earthquake recovery programme – a multi-million-pound package of loans to Turkey aimed at supporting the national catastrophe insurance scheme and providing insurance to all Turkish households.

Turkey sits on a major fault-line that threatens to raise Istanbul. Last August, an earthquake caused massive devastation in the area surrounding Turkey's capital, Ankara, when it claimed tens of thousands of lives.

Willis put together a consortium of leading Turkish and British consultants. Its partners include Bogazici University, Istanbul Technical University, London Economics, Cambridge Architectural Research and Oracle Corporation UK.
