SGER: Galeras Volcano 1991 Eruption Studies

1991年11月，哥伦比亚的加拉斯火山显示出许多即将爆发的迹象，与几年前邻近的鲁伊斯火山爆发前的情况非常相似，造成2万多人丧生。这笔赠款将使PI和他的学生能够在火山爆发之前前往哥伦比亚，在火山侧面建立一个小型地震网络。然后，他们将尝试将地震与COSPEC确定的特定气体排放联系起来。这些关于地震活动性和气体排放之间关系的信息对于预测未来类似火山的喷发非常重要。如果pi在那里的时候没有火山喷发，当地地质学家就会用这些设备来测量火山喷发的时间和时间。

In November, 1991 Galeras Volcano in Colombia showed numerous signs of impending eruption, very similar to those of the neighboring volcano Ruiz just before it erupted a few years ago with a loss of over 20,000 lives. This grant will enable the PI and his student to go to Colombia before any eruption comes and establish a small seismic network on the flanks of the volcano. They will then try to correlate seismic tremors with specific gas emissions as determined by COSPEC. This information about the relationship between seismicity and gas emission could be very important in attempts fo predict future eruptions of similar kinds of volcanoes. If no eruption occurs while the PIs are there, local geologists will use the equipment to make measurements when and if it does occur.
