00:00:00,050 --> 00:00:03,900

In this data visualization, you can see

an earthquake strike under

2

00:00:03,900 --> 00:00:07,950

the Pacific Ocean in purple

and the tsunami it generated in white.

3

00:00:08,516 --> 00:00:12,016

The red orange, yellow and green ringlets you see here

4

00:00:12,250 --> 00:00:15,616

are, in part, atmospheric disturbances

caused by the event.

5

00:00:16,316 --> 00:00:20,183

Every ringlet you see is a real time

reading from ground stations

6

00:00:20,183 --> 00:00:21,600

around the globe.

7

00:00:21,600 --> 00:00:25,500

The disturbances were picked up by NASA's experimental

system GUARDIAN,

8

00:00:25,816 --> 00:00:28,466

just eight minutes

after the earthquake.

9

00:00:28,750 --> 00:00:33,266

In Hawaii, GUARDIAN flashes red and orange as it picks up the incoming wave,

10

00:00:33,700 --> 00:00:36,650

32 minutes

before the tsunami makes landfall

11

00:00:36,650 --> 00:00:39,933

and is detected by the tidal gauges,

seen here in blue.

12

00:00:40,600 --> 00:00:43,166

There is no stopping a tsunami, but NASA's

13

00:00:43,166 --> 00:00:46,733

GUARDIAN could provide communities

precious time to prepare.
