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.
One of the simpler ways to answer is that an active volcano is one that has erupted since the last ice age (i.e., in the past ~10,000 years). That is the definition of active used by the Global Volcanism Program in their catalogs. A dormant volcano would then be one that hasnât erupted in the past 10,000 years, but which is expected to erupt again. An extinct volcano would be one that nobody expects to ever erupt again. These are human definitions of natural things â there have been a number of eruptions from âextinctâ volcanoes!
