The Kapenga volcanic center was active from sometime between 890 to 710 thousand years ago (ka) and again from about 280 to 270 ka and contains two collapse structures and rhyolitic lava domes (Wilson et al. 1984, Houghton et al. 1995). The NE center, previously considered part of the Okataina center, contains numerous pre-50 ka rhyolitic domes and was the source of the ca. 65 ka Earthquake Flat Breccia. No eruptive activity is known from the Holocene.
