Kanaga T8/Yellow-Brown-Olive Ash
Start: 1873 yBP [1]
Stop: 1570 yBP [1]
Event Type: Explosive
- Pyroclastic flow, surge, or nuee ardente [1]
Description: From Waythomas and others (2001): "Groups of tephra deposits so defined indicate that at least 11 eruptions of Kanaga Volcano have occurred since about 11 ka. Most of these eruptions were probably sub-Plinian to Plinian, producing moderately vesicular dacitic pumice lapilli tephra deposits ranging in thickness from a few centimeters to more than 1 m (table 2 [in original text])."
"Pumice-lapilli fall and flow deposit."
Waythomas and others (2001) correlate T8 on Kanaga with the Yellow-Brown-Olive Ash of Black (1980) on Adak Island, based on age equivalency.
