In 1920, the Volcanological Survey of Indonesia was created in order to investigate, record, and warn people about volcanoes within the Indonesian region. This group has helped aid in the evacuation of people living near Indonesian volcanoes since it was formed. For example, during the 1982 eruption of Galunggung, which had a Volcanic Explosivity Index of 4, 75,000 people were evacuated and 68 people died, and in 1988, 15,000 people were evacuated and there were no fatalities during the eruption of Makian.
