Doing The Improvement

So it's, you know, it's, it's very real. And I think it comes with some very real responsibility. Different parts of the world have different types of earthquake alert and monitoring systems. Do you think using phones is the. The best way forward for this kind of tech it's pretty clear that the systems that are based on professional seismic network,s usually operated by a civil authority of some so, rt as Japan, Taiwan has and Mexico Here in the western US that's that's a gold standard as compared to this method on the other hand the.

Phones are, you know, they're ubiquitous obviously, and Google has really shown that the sheer numbers of them can allow for an innovative earthquake detection system. There are many countries around the world that you know, that don't have the resources or the seismic networks to operate a kind of more professional instrument-based earthquake.

Early warning system. And I think that there's value in a system like this, to fill that gap. But again, you know, that's, that's a trade off and I think it's one that people have to enter into with very open eyes in any given country.

Professor Harold Tobin, thank you for joining us. We did ask Google about the new data. They explained to us exactly how many alerts were sent out at the time, the company said. We presented A detailed review of thesystem'ss performance in the paper, including what we learned from these earthquake events and improvements made.
