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.
A volcano is generally a conical-shaped hill or mountain built by accumulations of lava flows, tephra, and volcanic ash. About 95% of active volcanoes occur at the plate subduction zones and at the mid-oceanic ridges (Figure 1).
