Abstract
Volcanic activity, which can read to various danger and hazards to human life, has been part of the Earth's history for a long time. There are approximately 1,520 volcanoes during the Holocene period (about 10,000 years ago) that have been active on Earth. Recently, there are about 210 volcanoes have been recorded since 2010. Meanwhile, there are 83 known active volcanoes in 2018 based on the USGS data. Approximately 80-90 volcanoes are active on Earth for over a year. More than 90% of these volcanoes are located on the circum-Pacific volcanic belt, commonly known as 'Ring of Fire'. This high number of active volcanoes within this area coincides with the distribution maps of active volcanoes on the earth: about 80% on subduction zone of the convergent plate boundaries; 15% on divergent plate boundaries and 5% on intra-plate zone. Five volcanoes are most active during the survey period of 51 weeks: 50 times in Aira (Japan), 49 times in Sabankaya (Peru), 49 times in Sheveluch (Russia), 44 times in Ebeko (Russia) and 40 times in Kirishimayama (Japan). Based on the available data about volcanic activity, there is no significant change in volcanic activity and similar levels of volcanic activity is observed every year.
