Unformatted text preview: Soon after the eruptions, Thomas and his crew were off to Homer Alaska which is 60 miles away from the volcano and began probing and measuring the lightning activity. They recorded some of the best observations of volcanic lighting ever which led to some new discoveries in understanding volcanoes. With this new data, scientist believe there are two types of volcanic lightning during an eruption, the first that has been understood for quite some time, occurs in the volcanoes smoke plume shortly after the eruption. The second (new discovery) type of lightning is caused by the spewing of magma, ash and rocks which in short create a great electrical charge that continuously surrounds the mouth of the volcano, causing the charge to spark. This is a revolutionary observation for geophysicists for they can now better understand both types of volcanic lightning....
