00:00:00.350 --> 00:00:02.460
NASA scientists have updated the first

2
00:00:02.480 --> 00:00:04.340
publicly available catalog of

3
00:00:04.360 --> 00:00:06.670
global rainfall-triggered landslides.

4
00:00:06.690 --> 00:00:07.120


5
00:00:07.140 --> 00:00:11.910
This map shows the location of roughly 6000 landslides since 2007.

6
00:00:11.930 --> 00:00:12.040


7
00:00:12.060 --> 00:00:14.360
The catalog was produced from online databases

8
00:00:14.380 --> 00:00:16.460
and media reports around the world.

9
00:00:16.480 --> 00:00:16.960


10
00:00:16.980 --> 00:00:20.100
Most landslides occur during the Northern Hemisphere summer,

11
00:00:20.120 --> 00:00:23.960
coinciding with tropical cyclone and East Asian monsoon seasons.

12
00:00:23.980 --> 00:00:24.230


13
00:00:24.250 --> 00:00:26.000
Heavy rains can trigger landslides

14
00:00:26.020 --> 00:00:29.400
by forming fast-moving flows of rock, mud and debris

15
00:00:29.420 --> 00:00:31.420
that pour down hillsides creating

16
00:00:31.440 --> 00:00:33.590
destruction to life, property and homes.

17
00:00:33.610 --> 00:00:33.920


18
00:00:33.940 --> 00:00:35.180
According to this catalog,

19
00:00:35.200 --> 00:00:38.380
rainfall-triggered landslides since 2007

20
00:00:38.400 --> 00:00:41.490
have killed more than 20,000 people.

21
00:00:41.510 --> 00:00:44.320
This map shows the distribution of deaths worldwide.

22
00:00:44.340 --> 00:00:47.420
The highest number of deaths is concentrated in parts

23
00:00:47.440 --> 00:00:49.460
of Asia and Southeast Asia.

24
00:00:49.480 --> 00:00:49.820


25
00:00:49.840 --> 00:00:52.960
Scientists will use rainfall measurements from NASA satellites

26
00:00:52.980 --> 00:00:54.820
in combination with the catalog

27
00:00:54.840 --> 00:00:57.470
to improve our understanding of where and how

28
00:00:57.490 --> 00:00:58.800
landslides occur.

29
00:00:58.820 --> 00:01:01.375
