Geologists have improved upon methods to map seabed rocks, helping us better understand underwater earthquakes and the tsunamis they can cause.
Their technique combines traditional 'acoustic mapping' with a newer method called 'full waveform inversion'. They found their new method enhanced their view of rocks along a fault line – a break in the Earth's crust – off the east coast of New Zealand’s North Island.
The researchers hope that their clearer view of the rocks around these fault lines – whose movements can trigger earthquakes and subsequent tsunamis – will help them better understand why such events happen.
Lead author Melissa Gray, from Imperial College London’s Department of Earth Science and Engineering, said: “We can now scan underwater rocks to see their properties in greater detail. Hopefully this will help us to better work out how earthquakes and tsunamis happen.”
