Then the river came and washed everything away.

Over the last century, floods have become the most common and deadly natural disaster on the planet.

Many countries currently lack effective early warning systems and alerts.

20 percent of flood fatalities occur in India.

[radio announcer in progress]  --see some of the highest rainfalls

- One of the most important variables during a crisis

There's so much work  that's already been done,

and we're trying to learn from  that work, build on that,

In India, where we're running our first pilot program,

the government has thousands of people who are measuring the water level

with what is effectively very long measuring sticks,

Which allows them to know whether the river

But it doesn't yet allow them to understand

exactly what areas  are going to be affected.

What neighborhoods, or even what villages.

We received a warning from the head of the village

in the morning, just a few hours before the flood hit.

- The response time is most crucial thing.

Reducing the response time always plays a very important and vital role

in the whole disaster management framework.

Advancement in technology would  help us better

- Flood forecasting was a very  exploratory project.

to try to do forecasting that would be accurate enough

Starting with the basic needs for getting information about what's going on,

- To be able to provide a forecast in real time,

we rely on the government  we're working with.

by adding accurate modeling to that process.

We start by collecting  thousands of satellite images

we generate hundreds of thousands of simulations

We receive the measurements from the government,

and cross those measurements with our simulations.

We can then send those forecasts to individuals

using Search, Maps, and Android notifications.

This is an example of an alert that we can produce.

This alert is actually--has  over 90 percent accuracy.

- Any information we can give, they will use.

Talking to people who've directly experienced severe floods,

and understanding what they really need, is incredibly important

This is an opportunity to collaborate on a global scale.

to use technology to try to make a difference.

than to do work we love, which is develop technology,

help people directly in a very profound way.

Our hope for the future is to give people

a few more days of warning before a flood occurs.

And to use AI to scale this, and provide these forecasts

anywhere in the world,  wherever people need them.

The Crisis Response and Research team is exploring ways  to use AI to provide earlier warnings

for other natural disasters including fires and earthquake aftershocks.
