Universal Coordinated Time UTC – ZULU is a 24 hour clock. During an eruption, if the wind is from the east at 10,000 feet (outflow), the tephra will fall on Vancouver, Canada in about an hour. If the Kulshan Wind is from the west (inflow) the tephra will fall on Merritt, BC in about 40 minutes. There are extremes in preparedness, of course. As a basis of my work I use the 2015 Profile of Earthquake Risk in the District of North Vancouver by Earthquake Canada, wherein they state that there is 30% chance of a M7.3 in the middle of the Salish Sea, say between North Vancouver, Nanaimo and Victoria, in the next 50 years, that will bring down 839 buildings, just among the 80,000 residents in the District of North Vancouver.

Mt Baker's hissing volcanic crater




July 12, 2007


SUBSCRIBE

Our group of nine climbers summitted Mt Baker in Washington's North Cascades mountain range. Near the summit, we stopped for a break at which time I videotaped and recorded the sound eminating from its crater.
The hissing sound originates from the crater whereas the roaring sound is the wind.

This south-east flank has the Serman Fumeroles
Steph Abegg sent us several aerial views into Sherman Crater taken on February 26. John Scurlock piloted the plane. The photos show once again that even in the depths of winter, fumarolic heat flow is sufficient to keep a fair amount of the talus and rock in the fumarole fields bare of snow.
