2013
marks record year for the number of volcanoes erupting across the
planet
5
December, 2013,
This
year will go down on record, as seeing the most volcanic eruptions
recorded in modern history. The previous number was set in 2010, at
82 volcanic eruptions for the year.
The number of volcanoes erupting
across the planet has been steadily rising from a meager number of
just 55 recorded in 1990. While most scientists may readily dismiss
any significance to the latest figures and may be quick to say the
planet is just experiencing normal geological activity, it does raise
other concerns about just what may be transpiring within the interior
of our planet.
The average number of volcanic eruptions per year
should be about 50 to 60; as of December 5, 2013, we already at 83.
Volcanic eruptions are one way the planet dissipates a dangerous
build-up of heat, magma, and pressurized gases.
The planet’s outer
core is thought to flirt with critical temperatures in the range of
around 4400 °C (8000 °F).
Any rise or major fluctuation in interior
gradient could have profound and disruptive effects on processes
whose very properties are government by convective heat emanating
from the planet’s outer core: magnetic field propagation, tectonic
plate movements, sea-floor spreading mechanics, and mantle plume
activity.
Mantle plumes or hotspots are thought to be the central
mechanism which fuels the vast underground chambers of many of the
world’s supervolcanoes
