Oil pipeline rupture by quake remains a worry
Kinder Morgan is expected to carry out more research on the potential seismic risk of a quake rupturing its Trans Mountain pipeline and spilling oil into Burrard Inlet.
Belcarra Mayor Ralph Drew says a just-completed review of area geologic faults funded by Kinder Morgan is a good start but more work is needed to answer outstanding questions about the danger.
Some geologists in the past have suggested a fault triggered the historic slump of the north face of Burnaby Mountain an estimated 15,000 years ago.
Drew's nightmare scenario is for some similarly violent seismic event to strike today near the pipeline Kinder Morgan intends to twin and close to the Westridge Marine Terminal, where large amounts of oil is stored in tanks on a hill above the inlet.
"It doesn't take much land movement to result in a fracture to a hard object like a metal pipe," Drew said.
