Case managers can serve as an early warning system; case management staff has daily contact with payers and can provide valuable insight into health plan policies and practices that may have a negative impact on hospital operations and finances.
A volcano is active if itâs currently erupting or showing signs of unrest. The Smithsonian Global Volcanism Program defines an active volcano as having erupted within the last 10,000 years. A volcano finally goes extinct when thereâs no lava supply in the magma chamber beneath the volcano.
Sleeping Giants. Volcanologists (geologists who study volcanoes) classify volcanoes as either active, dormant, or extinct. An active volcano is a volcano that is currently erupting or has erupted recently, such as Mount St. Helens, which most recently erupted in 1980.A dormant volcano is one that has not erupted recently but is expected to do so again. Prior to its 1980 eruption, Mount St. Helens had been classified as dormant.n extinct volcano is a volcano that volcanologists do not think will ever erupt again, such as Mount Buninyong in Australia. It is often difficult to determine which volcanoes are extinct and which are dormant.
