An earthquake in the eastern Aleutian Trench big enough to generate a massive tsunami like the one in the study is expected to occur once every thousand years, meaning that there is a 0.1 percent chance of it happening in any given year — the same probability as the 2011 Tohoku earthquake that struck Japan, according to Gerard Fryer, a geophysicist at the
Pacific Tsunami Warning Center in Ewa Beach, Hawaii.
«This event did not produce a tsunami,» Segall says, «but if we can detect potentially catastrophic ground motion in its early stages, we might be able to
issue tsunami warnings in the future.»

Now, researchers have come up with a way to more quickly gauge a big quake's magnitude and thus provide faster, more
accurate tsunami warnings: by measuring the miniscule changes in Earth's gravitational field that are generated when massive slabs of the planet's crust shift by dozens of meters over the course of a few minutes.

In principle, such a system would be similar to the one in the United States,
where tsunami warnings are handled by the National Oceanic and Atmospheric Administration.
The Indian
Ocean Tsunami Warning and Mitigation System (IOTWMS)-- like its long - established counterpart in the Pacific Ocean region — is designed to bring together seismic - monitoring measurements, sea - level gauges, computer - model - based threat evaluation and logistics to disseminate and act on timely warnings.
But with parts of coastal Japan — which had the best system — now lying in ruins, will scientists be able to improve the warning time given by near -
field tsunami warning systems?

One indispensable and thankless Unesco task is
organizing tsunami warnings systems and pushing for tsunami education on risky shores around the world.
For example, having of the signals on pre - earthquakes /
pre tsunami warning (and of course with well structured quakes resistant buildings should be built, not just built on cheaper materials which costs lives) will atleast saves more vulnerable lifes.
Now the task is, in part, to explore ways to ensure that the lessons of the Japanese disaster don't erode like the fading, forgotten inscriptions on the centuries -
