>> And I was installing GPS measurements,

that a earthquake hazard should be higher up on their list.

>> They were able to provide a likely scenario in that

means that probably more attention should be paid

to scientists when they talk to authorities about hazards.

>> Are able to measure the position of benchmarks

that we install in blocks, with a precision of a millimeter.

So if those benchmarks move because there is deformation

If you want to know the probability of an earthquake

to know how fast a strain, elastic energy if you want,

And that's where we are measuring essentially

This technique has been out there for about 15 years

at the level of precision that we have today.

to analyze much more data much more quickly

So we'll also be re-measuring the benchmark

that we have installed in the past on that fault,

and be able to look at the difference before

versus after the earthquake, and learn about the mechanics

After an earthquake it takes months, years perhaps,

for the whole area of the Earth's crust around the fault

And this recovery process is very important

about the mechanical properties of the Earth's crust.

So we have to jump at every opportunity we have to do that.

We can only do that when there is an earthquake.

So when the earthquake happened, we run out there to be able

something you cannot do there easily in the lab.
