What if there was a better way to detect tsunamis faster?

If the cable is closer to the trench that causes the earthquake, it can give significantly more early warning.

It's Friday, April 26th, and you guessed it, it's Science Friday. I'm Cyfry producer Kathleen Davis. The bottom of the sea is home to a wide

network of telecommunication cables. These are responsible for getting us our internet and

connecting us to the world. For decades, researchers have thought, what if we can use these

telecommunication cables as a way to detect earthquakes and tsunamis as early as possible?

We'll explore that story in just a little bit.

But first, here's Ariel Dum Ross with the biggest science stories of the week.

It was 10 years ago when city officials in Flint, Michigan switched their water source to the Flint River,

a move that was projected to save the city five million dollars.

Instead, the water corroded the city's lead pipes, which in turn caused a lead poisoning crisis,

as well as an outbreak of Legionnaires disease, which itself killed around a dozen people.

So where do things stand now? Here to give us an update on the Flint Water crisis, and to tell us about other top science stories this week is Umer Erfan,

senior correspondent to Ed Vox.

Welcome to Science Friday, Umer.

Hey Ariel, thanks for having me.

Thank you so much for being on the show. So it seems... Umer. Hey Ariel, thanks for having me.

Thank you so much for being on the show.

So it seems that a decade later some people in Flint still don't know if they have clean water.

How could that possibly be? Right, that's one of the key sources of frustration.

Even though this was a national story,

it became a huge scandal that went all the way up to the President of the United States.
