WHAT DOES A VOLCANO SOUND

00:08.500 --> 00:10.266 position:10% line:85% size:80%
LIKE?

00:10.266 --> 00:11.734 position:10% line:85% size:80%
HERE'S AN EXAMPLE OF AN ERUPTION

00:11.734 --> 00:13.000 position:10% line:85% size:80%
IN A HOUSING AREA NEAR THE

00:13.000 --> 00:14.867 position:10% line:85% size:80%
VOLCANO KILAUEA IN HAWAII.

00:14.867 --> 00:17.166 position:10% line:85% size:80%
(ROARING ERUPTION)

00:17.166 --> 00:18.333 position:10% line:85% size:80%
THE FOUNTAINS OF LAVA

00:18.333 --> 00:20.700 position:10% line:85% size:80%
WERE AT LEAST 300 FEET HIGH.

00:20.700 --> 00:23.166 position:10% line:85% size:80%
IN THIS EXAMPLE A FISSURE OPENED

00:23.166 --> 00:24.633 position:10% line:85% size:80%
UP ON SOMEONE'S DRIVEWAY NEAR

00:24.633 --> 00:27.100 position:10% line:85% size:80%
KILAUEA.

00:27.100 --> 00:29.066 position:10% line:85% size:80%
SOUND IS A VERY IMPORTANT CLUE

00:29.066 --> 00:31.433 position:10% line:85% size:80%
TO WHAT A VOLCANO IS DOING.

00:31.433 --> 00:33.066 position:10% line:85% size:80%
LAVA AND GAS MOVE AROUND UNDER

00:33.066 --> 00:34.633 position:10% line:85% size:80%
THE GROUND AND MAKE NOISE.

00:34.633 --> 00:36.066 position:10% line:85% size:80%
THOSE SOUNDS ARE MUCH TOO LOW

00:36.066 --> 00:37.533 position:10% line:85% size:80%
FOR HUMANS TO HEAR, BUT

00:37.533 --> 00:38.800 position:10% line:85% size:80%
SCIENTISTS USE SPECIAL

00:38.800 --> 00:40.433 position:10% line:85% size:80%
INSTRUMENTS TO RECORD THOSE

00:40.433 --> 00:41.967 position:10% line:85% size:80%
SOUNDS AND EARTHQUAKES.

00:41.967 --> 00:43.533 position:10% line:85% size:80%
AND BY STUDYING THOSE RECORDINGS

00:43.533 --> 00:44.800 position:10% line:85% size:80%
SCIENTISTS CAN GET AN IDEA OF

00:44.800 --> 00:46.533 position:10% line:85% size:80%
WHAT MAY BE GOING ON DEEP INSIDE

00:46.533 --> 00:47.800 position:10% line:85% size:80%
THE VOLCANO.

00:47.800 --> 00:49.233 position:10% line:85% size:80%
AND THAT MAY HELP THEM FORECAST

00:49.233 --> 00:51.533 position:10% line:85% size:80%
FUTURE ERUPTIONS AND SAVE LIVES.
