Emmons Intracaldera activity
Start: 126000 yBP [1]
Event Type: Effusive
- Lava flow [1]
Description: From Waythomas and others (2006): "At least two distinct episodes of intra-caldera andesitic volcanism have been documented at the Emmons Lake volcanic center. During the first episode, at least four andesitic lava flows were erupted between the Volcano Bay and Boundary calderas in the southernmost part of the caldera complex (unit ol, fig.8 [in original text]) about 126,000 years B.P."
