Since then, thermal anomalies (hot spots) and gas emissions (including hydrogen sulfide) have occurred especially on the summit plateau and indicate that Adams is dormant, not extinct. Future eruptions from Adams will probably follow patterns set by previous events and will thus be flank lava flows of andesite or basalt. Because the primary products were andesite, the eruptions that occur on Adams tend to have a low to moderate explosiveness and present less of a hazard than the violent eruptions of St. Helens and some of the other Cascade volcanoes. However, since the interior of the main cone is little more than a pile of fragmented lava and hydrothermally-altered rock, there is a potential for very large landslides and other debris flows.
