Eruptive History

There is data available for 3 confirmed Holocene eruptive periods.

0080 ± 60 years Confirmed Eruption (Explosive / Effusive)  

Episode 1 | Eruption (Explosive / Effusive) Paloc Pyroclastics
0080 ± 60 years - Unknown Evidence from Isotopic: 14C (uncalibrated)
 Paloc pyroclastic deposits were 14C dated at 1,800 and 1,870 ± 60 years BP (Ramos et al., 2000). Several Holocene thermoluminescence dates (some as young as several hundred years) were obtained from lava domes and pyroclastic deposits, but Ramos et al. (2000) noted that these ages were significantly younger than comparable radiocarbon ages and suggested uncertainty about their reliability.

Episode 1 | Eruption (Explosive / Effusive) Paloc Pyroclastics
4092 BCE ± 122 years - Unknown Evidence from Isotopic: 14C (uncalibrated)
 Paloc pyroclastic deposits were radiocarbon dated at 6,042 ± 122 years BP (Ramos et al., 2000). Several Holocene thermoluminescence dates (some as young as several hundred years) were obtained from lava domes and pyroclastic deposits, but Ramos et al. (2000) noted that these ages were significantly younger than comparable radiocarbon ages and suggested uncertainty about their reliability.
