JOAN CARTAN-HANSEN, HOST:

00:00:06,734 --> 00:00:08,500
WHAT DOES A VOLCANO SOUND

4
00:00:08,500 --> 00:00:10,266
LIKE?

5
00:00:10,266 --> 00:00:11,734
HERE'S AN EXAMPLE OF AN ERUPTION

6
00:00:11,734 --> 00:00:13,000
IN A HOUSING AREA NEAR THE

7
00:00:13,000 --> 00:00:14,867
VOLCANO KILAUEA IN HAWAII.

8
00:00:14,867 --> 00:00:17,166
(ROARING ERUPTION)

9
00:00:17,166 --> 00:00:18,333
THE FOUNTAINS OF LAVA

10
00:00:18,333 --> 00:00:20,700
WERE AT LEAST 300 FEET HIGH.

11
00:00:20,700 --> 00:00:23,166
IN THIS EXAMPLE A FISSURE OPENED

12
00:00:23,166 --> 00:00:24,633
UP ON SOMEONE'S DRIVEWAY NEAR

13
00:00:24,633 --> 00:00:27,100
KILAUEA.

14
00:00:27,100 --> 00:00:29,066
SOUND IS A VERY IMPORTANT CLUE

15
00:00:29,066 --> 00:00:31,433
TO WHAT A VOLCANO IS DOING.

16
00:00:31,433 --> 00:00:33,066
LAVA AND GAS MOVE AROUND UNDER

17
00:00:33,066 --> 00:00:34,633
THE GROUND AND MAKE NOISE.

18
00:00:34,633 --> 00:00:36,066
THOSE SOUNDS ARE MUCH TOO LOW

19
00:00:36,066 --> 00:00:37,533
FOR HUMANS TO HEAR, BUT

20
00:00:37,533 --> 00:00:38,800
SCIENTISTS USE SPECIAL

21
00:00:38,800 --> 00:00:40,433
INSTRUMENTS TO RECORD THOSE

22
00:00:40,433 --> 00:00:41,967
SOUNDS AND EARTHQUAKES.

23
00:00:41,967 --> 00:00:43,533
AND BY STUDYING THOSE RECORDINGS

24
00:00:43,533 --> 00:00:44,800
SCIENTISTS CAN GET AN IDEA OF

25
00:00:44,800 --> 00:00:46,533
WHAT MAY BE GOING ON DEEP INSIDE

26
00:00:46,533 --> 00:00:47,800
THE VOLCANO.

27
00:00:47,800 --> 00:00:49,233
AND THAT MAY HELP THEM FORECAST

28
00:00:49,233 --> 00:00:51,533
FUTURE ERUPTIONS AND SAVE LIVES.
