Key Focus

Some gases from Mount Ruang's eruptions climbed so high they punched into the stratosphere, the second layer of Earth's atmosphere. It's located just above the troposphere, which is where all life and weather occur. ...

In 1991, Mount Pinatubo - another stratovolcano - erupted in the Philippines and produced the largest sulfur dioxide cloud ever measured. ...
