General Information

Eruptive History

There is data available for 2 confirmed eruptive periods.

0648 (in or after) ± 11 years Confirmed Eruption (Explosive / Effusive) VEI: 0

Episode 1 | Eruption (Explosive / Effusive) Shamao
0648 (in or after) ± 11 years - Unknown Evidence from Isotopic: Uranium-series
 A measured (226Ra/230Th) activity ratio of the Shamao dome magnetite separate yielded a maximum time of 1,367 ± 11 years (2 sigma) years before the analysis (2015 CE), making the eruption date no earlier than 648 ± 11 CE (Zellmer at al., 2015).

Episode 1 | Eruption (Explosive / Effusive) Cisingshan
4095 BCE ± 35 years - Unknown Evidence from Isotopic: 14C (calibrated)
 A phreatic eruption from a fissure on the west side of Cising lava dome took place at the time of the Cising debris avalanche, which has a calibrated age of about 6,010-6,080 years BP (Belousov et al., 2010). The fissures contain small funnel-shaped craters that were the sources of explosive breccias several hundred meters wide and several meters thick that were considered to possibly be related to lithostatic unloading of the youngest lava flows, which may have occurred only a few years before the collapse and 0.05 km3 debris avalanche.
