Magma Monday: Image of an inflating volcano. This is an image, produced from radar data, of Kilauea volcano, Hawaii, showing the bulging of its surface due to arrival of magma into a magma chamber underneath. Each purple color stripe represents about 1.5 cm of surface rise. Since there are 7 purple stripes towards the center of the bullseye, the amount of surface bulging in the center is about 10 cm. This inflation event happened in April, 2015, accompanied by lava spilling out of the central crater in upper right center. (From USGS)
