Danger is ubiquitous but accurate and timely warnings of it are relatively rare; proper risk assessment is one of the great policy challenges of our time.

Years ago, I lived in Italy on the bank of Lago d’Averno, just north of Naples. Described by the poet Virgil as the entrance to Hell, the lake is close to the tunnels of Cumae, where in ancient times the Sybil used to utter carefully vague prophecies.

This plan relied on advance warning from scientists of an eruption. A quick glance at the local road network and the densely packed housing surrounding all the volcanic craters of the Campi Flegrei suggested, however, that in practice the plan was unlikely to work well. The whole area seemed to have been developed without much thought of the danger. The prevailing attitude to the risk of disaster seemed remarkably blasé….
