The movie showed in the “Effusive Volcanism” section was a documentary about a case study of the lavas of Hawaii. The documentary showed that the scientists developed a mapping program to evaluate the current lava flows from the Kilauea’s eruption, which had destroyed about 180 homes. By using the mapping program to show the accurate direction and predict the speed of the lava flows, they would be able better evaluate hazards in the next eruption. The scientist also told that the knowledge and experiences scientists learned from Hawaii Volcano Observatory had helped them understand how volcanoes work at other eruption active places like Iceland and other hot spots. The color of the lavas was bright orange when they were first erupted, and
