Iliboleng is a stratovolcano located in Indonesia, standing at an elevation of 1,659 meters. Its tectonic setting is classified as a subduction zone with crustal thickness unknown. According to official records from the Smithsonian Global Volcanism Program, the volcano has a documented history of 20 confirmed eruptions spanning across the 19th and 20th centuries CE.
Overview of Historical Eruptions
The historical record for Iliboleng captures 20 confirmed eruptions between 1885 CE and 1993 CE. All recorded eruptions relied on reported observations as their evidence method. The activity recorded across this timeframe reached a largest recorded Volcanic Explosivity Index (VEI) of 2.0.
When broken down by century, the structured collection documents 2 eruptions during the 19th century CE (beginning with the 1885 CE event) and 18 eruptions during the 20th century CE. The earliest recorded eruption in the dataset started on September 16, 1885 CE, and ended on October 16, 1885 CE. The latest confirmed eruption in the official record began on June 16, 1993 CE, and concluded on July 16, 1993 CE, carrying a VEI of 1.0.
Chronological Examples of Recorded Activity
The 20 confirmed eruptions feature varying durations and explosivity levels documented through reported observations. Representative entries from the official eruption history include:
- September 16, 1885 CE – October 16, 1885 CE: A confirmed eruption with a VEI of 2.0.
- July 2, 1927 CE: A confirmed eruption with a VEI of 2.0.
- March 16, 1950 CE – August 16, 1950 CE: A confirmed eruption with a VEI of 2.0.
- October 2, 1987 CE: A confirmed eruption with a VEI of 2.0.
- June 16, 1993 CE – July 16, 1993 CE: A confirmed eruption with a VEI of 1.0.
The remaining 15 eruptions in the collection share similar observational characteristics within the 1885 CE to 1993 CE period, all maintaining recorded VEI values between 1.0 and 2.0.
