SUBDUCTION ZONES and ISLAND ARCS. Subduction Zones are where cool lithospheric plates sink back into the mantle. It takes about 50 my for the ocean lithosphere that formed in the hot (>1000C) environment at mid-ocean ridges to cool to an equilibrium state and sink to its maximum depth below sea-level.
Ebola hemorrhagic fever is a viral disease caused by Ebola virus that results in nonspecific symptoms (see symptom section of this article) early in the disease and often causes internal and external hemorrhage (bleeding) as the disease progresses.
Ebola and Marburg viruses cause hemorrhagic fever in humans and nonhuman primates. Five species within the genus Ebolavirus have been identified: Tai Forest ebolavirus (TaÃ¯ Forest virus), Sudan ebolavirus (Sudan virus), Zaire ebolavirus (Ebola virus), Bundibugyo ebolavirus (Bundibugyo virus), and Reston ebolavirus (Reston virus).
