SGER: Galeras Volcano 1991 Eruption Studies

1991年11月，哥伦比亚的加雷拉斯火山显示出许多即将喷发的迹象，与邻近的鲁伊斯火山非常相似，几年前鲁伊斯火山喷发，造成2万多人死亡。这笔赠款将使PI和他的学生能够在任何喷发到来之前前往哥伦比亚，并在火山侧翼建立一个小型地震台网。然后，他们将尝试将地震震动与COSPEC确定的特定气体排放联系起来。这些关于地震活动和气体排放之间关系的信息可能对预测未来类似类型的火山喷发非常重要。如果在PI存在的情况下没有喷发，当地地质学家将在发生喷发时使用该设备进行测量。

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.
