Atlantic tsunami risk

Warning from Matt Owen and Mark Maslin

Atlantic tsunami risk

The August issue of Nature Geoscience includes a correspondence piece from Dr Matt Owen and Professor Mark Maslin which addresses the Atlantic tsunami threat.

 Although the annual probability of tsunamis is lower in the Atlantic than in the Pacific and Indian oceans, the human exposure along highly populous coastlines means that the Atlantic risk is still significant and should be mitigated. The tsunami associated with the 1755 Lisbon earthquake, for example, killed thousands, and its human impact today would be much greater.

The article suggests that existing coastal defences for storm surges could include a contingency for the rare tsunami event, including the need for a much more rapid evacuation response.
