<< Slide Image Left On The Website Mastheads (here and elsewhere) Good morning, everyone. In the 1950s, my father helped build the dams and tunnels at Kemano to help provide power for the Kitimat aluminum smelters.

I experienced my first magnitude 7.0-7.5 earthquake when I was almost 23 months old. It almost knocked me to the ground. That 1946 Vancouver Island earthquake struck Vancouver Island on June 23 at 10:15 a.m.[1] with a magnitude estimated at 7.0 Ms[2] and 7.5 Mw.[6] The main shock epicenter occurred in the Forbidden Plateau area northwest of Courtenay. While most of the large earthquakes in the Vancouver area occur at tectonic plate boundaries, the 1946 Vancouver Island earthquake was a crustal event. Shaking was felt from Portland, Oregon, to Prince Rupert, British Columbia. This is one of the most damaging earthquakes in the history of British Columbia, but damage was restricted because there were no heavily populated areas near the epicentre, where severe shaking occurred. There were, however, a whole series of landslides in the Forbidden Plateau area there were a whole series of landslides blocked streams and rivers to create lakes. The first hikers into the area gave them great names, Landslide Lake, Rock Fall Lake, Earthquake Lake etc.; over time these natural dams were eroded to nothing, leaving nothing but fading memories of those lakes. This earthquake is Canada's largest historic onshore earthquake.[1] Three years later, an earthquake, an M8.1, struck at 8:01 p.m. PDT on August 2, 1949 in Haida Gwaii [formerly Queen Charlotte Islands], an interplate earthquake that occurred on the ocean bottom just off the west coast of the main south island [Graham Island]. The shock had a surface wave magnitude of 8.1 and a maximum Mercalli Intensity of VIII (Severe).

Gas Tanker - Jettisoning Liquid Gas -163°C (-262°F) On Open Sea

After this video is started, TO VIEW FULL SCREEN, click on YouTube Icon at the bottom right.  That will open a new window which can be expanded to FULL SCREEN >> SOUND ON.  When that window is closed you will return here.

Old footage showing Methane jettisoning test on open sea from LNG Vessel Cargo tank rupture caused by increase of pressure - Emergency procedure for gas carriers Cargo tank ruptures due to increased pressure are highly improbable with the existing tank protection systems. There are multiple devices/systems protecting the cargo tanks - it is almost impossible for all devices to fail at the same time. Additionally, cargo tanks may support much higher pressure than the actual settings of the relief valves. However in this scenario we have two different situations - whether the affected tank is loaded or empty: . If the tank is empty the risk is less as no liquid cargo will be released. In that case, the hold space should be inerted at once. If the tank contains cargo and it is liquid cargo that is released: A minor leak may be controlled by via the hold space ejector LNG tanks internal barrier LNG tanks internal barrier A major leak may be impossible to control. In that case the two main options available are either abandonment or the jettisoning of the cargo In either case the first indication will be by the one or more of the detection systems - the gas detector, level switch or temperature sensor.
