  <dc:description>Since 1980, scientists have monitored geologic unrest in Long Valley Caldera and at adjacent Mammoth Mountain, California. After a persistent swarm of earthquakes beneath Mammoth Mountain in 1989, earth scientists discovered that large volumes of carbon dioxide (CO&lt;sub&gt;2&lt;/sub&gt;) gas were seeping from beneath this volcano. This gas is killing trees on the mountain and also can be a danger to people. The USGS continues to study the CO&lt;sub&gt;2&lt;/sub&gt; emissions to help protect the public from this invisible potential hazard.</dc:description>
