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
