Mount E last erupted on June 8, 1874. This eruption consisted of phreatic explosions and was rated a 1 on the VEI scale.^[4]

The oldest recorded eruption started November 18, 1846. The eruption triggered lahars damaging several houses and causing fatalities.^[4]^[5]

Radiocarbon dating and tephrochronology indicate five other eruptions predating the historical records in the approximate years 1350, 550 BC, 1050 BC, 3900 BC ±100 years, 7050 BC. The eruption in 7050 BC was the largest with a VEI of 3.^[4]
