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.
The world's biggest active volcano, Mauna Loa, has been rumbling back to life, with seismic and deformation monitoring data showing increasingly frequent small earthquakes. This increased activity at the volcano, on Hawaii's Big Island, has been detected as early as 2013 and could be a signal of an impending eruption. Mauna Loa, which is one of the world's most active volcanoes, has not erupted since 1984. The Volcano Alert Level was raised from Normal status to Advisory on 15 September 2015. Scientists at the US Geological Survey Hawaiian Volcano Observatory said the change indicated increased signs of unrest â but that this does not mean an eruption is imminent or certain.
