5 ways climate change boosts tsunami threat, from collapsing ice shelves to sea level rise

Climate-linked geological changes can increase the incidence of earthquakes and volcanic eruptions which, in turn, can exacerbate the threat of tsunamis. Sea level riseIf greenhouse gas emissions remain at high rates, the average global sea level is projected to rise between 60 centimetres and 1.1m. Volcanic activity from ice meltingAbout 12,000 years ago, the last glacial period (“ice age”) ended and the melting ice triggered a dramatic increase in volcanic activity. Increased earthquakesThere are a number ways climate change can increase the frequency of earthquakes, and so increase tsunami risk. This could include incorporating projected sea level rise into tsunami prediction models, and in building codes for infrastructure along vulnerable coastlines.
