The
Mount
Meager massif
is a group of volcanic peaks in the Pacific
Ranges
of the Coast
Mountains
in southwestern British
Columbia,
Canada. Part of the Cascade
Volcanic Arc
of western North America, it is located 150 km (93 mi) north of
Vancouver
at the northern end of the Pemberton
Valley
and reaches a maximum elevation of 2,680 m (8,790 ft). The massif is
capped by several eroded volcanic edifices, including lava
domes,
volcanic
plugs
and overlapping piles of lava flows; these form at least six major
summits
including Mount Meager which is the second highest of the massif.
The
Garibaldi
Volcanic Belt
(GVB) has a long history of eruptions and poses a threat to the
surrounding region. Any volcanic
hazard
ranging from landslides
to eruptions could pose a significant risk to humans and wildlife.
Although the massif has not erupted for more than 2,000 years, it
could produce a major eruption; if this were to happen, relief
efforts would be quickly organized. Teams such as the Interagency
Volcanic Event Notification Plan
(IVENP) are prepared to notify people threatened by volcanic
eruptions in Canada.
The
Mount Meager massif produced the largest volcanic eruption in Canada
in the last 10,000 years. About 2,400 years ago, an explosive
eruption
formed a volcanic
crater
on its northeastern flank and sent avalanches of hot ash, rock
fragments and volcanic
gases
down the northern flank of the volcano. Evidence for more recent
volcanic activity has been documented at the volcano, such as hot
springs
and earthquakes.
The Mount Meager massif has also been the source of several large
landslides in the past, including a massive debris
flow
in 2010 that swept down Meager
Creek
and the Lillooet River.
