Ninety-nine per cent of all tsunami-related deaths have occurred in the Asia-Pacific region, according to the United Nations Economic and Social Commission for Asia and the Pacific. Indonesian and Australian scientists have been working to reduce this figure—by creating artificial earthquakes and tsunamis.
Building off more than 15 years of research from Indonesian, Singaporean, American, and Australian scientists, the team created a collection of scenarios, for earthquakes of different magnitudes and the resulting tsunamis that would affect West Sumatra, Indonesia.
The 2004 Boxing Day tsunami devastated coastal communities around the Indian Ocean and left people asking what are the risks of future tsunamis and super storms? The answers can be found, at least in part, in the prehistory of coastlines.
Working together, researchers in Japan and Australia are getting better at predicting the areas most at risk from earthquakes.
They are also working together on ways to determine, within seconds of a warning, the scale and likely impact of an earthquake. Rapid detection and warning systems combined with smart engineering saved many lives in the Great Japanese Earthquake of 2011. But the earthquake and the resulting tsunami were much bigger than geological modelling suggested. The reasons for that might be found in deep history.
Mapping the hazard
Big earthquakes may be separated by centuries or millennia. But earthquake hazard maps are based on information gathered since 1900 when modern seismographs came into use. It’s difficult to model events happening over millennia when you have not got deep historical information. Continue reading Reducing the impact of earthquakes→
