Alaska Cleveland volcano shows signs of impending eruption. “thermal anomalies” detected by satellite. could disrupt air travel

The advisory was based on “thermal anomalies” detected by satellite, the observatory said. Those measurements indicate the volcano could erupt at any moment, spewing ash clouds up to 20,000 feet above sea level with little further warning, the observatory said.

Although Cleveland is among the most active of Alaska’s roughly 90 volcanoes, no seismic equipment is set up there because the costs of working in such a remote area are prohibitive, observatory officials said.
