SGER: Galeras Volcano 1991 Eruption Studies

1991年11月，哥伦比亚的加列拉斯火山出现了许多迹象， 即将爆发，非常类似于邻近的 几年前，鲁伊斯火山爆发， 超过两万条生命 这笔赠款将使PI和他的学生 在火山爆发前前往哥伦比亚， 火山两侧的地震网络 然后他们会尝试 将地震震动与特定气体排放量联系起来， 由COSPEC确定。 关于这段关系的信息 地震活动和气体排放之间的联系可能非常重要， 预测未来类似火山爆发的尝试。 如果PI在那里时没有发生喷发，当地地质学家 如果有，我将使用设备进行测量 发生.

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.
