According to the Smithsonian Global Volcanism Program, the volcano has a recorded history of 38 confirmed eruptions spanning from deep antiquity up to the late 20th century. The largest recorded Volcanic Explosivity Index (VEI) for Yakedake reaches 4.0.
Overview of Eruption History
The historical record for Yakedake comprises 38 confirmed eruptions captured across multiple centuries. The earliest recorded event in the official data dates back to 7450 BCE on the Akandana-yama activity area, recorded with a VEI of 0.0 using tephrochronology correlation methods. Over millennia, activity has manifested through various eruptive phases across different flanks and summit craters, such as the 350 BCE eruption which reached a VEI of 4.0 determined by calibrated radiocarbon isotopic evidence.
Centuries of subsequent activity include events recorded in the 26th century BCE, the 4th, 7th, and 9th centuries BCE, as well as the 7th, 13th, 15th, 16th, 18th, and 20th centuries CE. The 20th century accounts for a significant portion of the documented events, totaling 26 confirmed eruptions within that timeframe. Notable historical events include an eruption from June 6, 1915, to July 16, 1915, originating from the 1911 summit crater on the southeast flank (Taisho period), which registered a VEI of 2.0 based on reported observations.
Latest Recorded Activity
The latest confirmed eruption in the official record occurred on the southeast flank (Azusa-gawa) on February 11, 1995, with a VEI of 1.0 based on reported observations. The profile's last known eruption year is recorded as 1995.
