00:00:02,769 --> 00:00:06,840
On the morning of April 9, 2021, La Soufrière volcano on the island of St. Vincent began to erupt.

2
00:00:06,840 --> 00:00:10,877
NOAA satellites monitored the event with detailed imagery.

3
00:00:10,877 --> 00:00:18,018
GOES-16 and NOAA-20 imagery shows the ash clouds high in the atmosphere 
drifting toward Barbados.

4
00:00:18,018 --> 00:00:26,626
Satellites also observed gravity waves caused by the eruption.

5
00:00:27,027 --> 00:00:35,869
NOAA-20 instruments detected "exceptionally large" aerosol measurements,
 a sign that ash had been lofted into the startosphere.

6
00:00:35,869 --> 00:00:44,477
Infrared imagery revealed cold cloud tops similar to severe thunderstorms.

7
00:00:44,477 --> 00:00:51,551
The Geostationary Lightning Mapper even observed lightning activity.

8
00:00:51,551 --> 00:00:59,492
Specialized GOES imagery highlighted volcanic ash and sulfur dioxide.

9
00:00:59,492 --> 00:01:07,300
NOAA satellites provide crucial information for monitoring volcanic eruptions 
and the hazards associated with them.
