Supervolcano
A
supervolcano
is any
volcano
capable of producing a
volcanic eruption
with an
ejecta
mass greater than 10
15
kg. Supervolcanoes can occur when
magma
in the
mantle
rises into the
crust
from a
hotspot
but is unable to break through the crust, and pressure builds in a large and growing magma pool until the crust is unable to contain the
pressure
(this is the case for the
Yellowstone Caldera
). They can also form at
convergent plate boundaries
(for example,
Toba
).
Large igneous provinces
can cover huge areas with
lava
and
volcanic ash
, causing long-lasting
climate change
(such as the triggering of a small
ice age
or
global warming
), which can
threaten species with extinction
.
