The buoys could be installed in the deep ocean—but this requires an unrealistic number of buoys. The second option is to install the buoys along the shoreline, but due to the high speed of the tsunami, that would leave no warning time for people on the land.

Here is the buoy which reported a 32 foot water rise shortly after the powerful 8. Acoustic waves that radiate from an earthquake can travel much faster than the tsunami that has been triggered. And for longer distances—thousands of kilometres—too, carrying information on the earthquake itself as well as the forthcoming tsunami waves.

How it works Using standard hydrophones underwater microphones we can record these sound waves long before the tsunami arrives, and regardless of the direction that the tsunami will travel.

The sound signals come from changes in pressure, so what we actually analyse is a series of data on how the pressure is changing over time. Though buoys also detect changes in pressure, the tsunami front must actually reach the buoys for us to know that there is an elevation in the water surface.

By using hydrophones, however, you only need to capture the sound signals. It is based on the assumption that the underwater faults which cause earthquakes are slender—the width is much smaller than the length, which is the case in many known eruptions.

By assuming this, we can then start to figure out how the sound has evolved as it moves. Using these, we can then not only warn of a tsunami but also more accurately estimate its size long before it reaches the shoreline.

With these data at hand, we can evaluate the impact the tsunami will have on the shoreline and provide a rapid threat assessment within just a few minutes of the initial signal being recorded. While we work to adapt our method so that it will run automatically, we anticipate that governments around the world will take the idea and use it to create a new, quicker, early warning system for coastal communities.Anti-Corruption: The Global Fight is a new handbook from IIP Publications that outlines the kinds of corruption, their effects, and the ways that people and governments combat corruption through legislative and civil society actions.
