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.
Most active volcanoes are strung like beads along, or near, the margins of the continents, and more than half en circle the Pacific Ocean as a Ring of Fire. Many volcanoes are in and around the Mediterranean Sea. Mount Etna in Sicily is the largest and hiqhest of these mountains. Italy's Vesuvius is the only active volcano on the European mainland.
