Ripple Rock
Ripple Rock (french: Roche Ripple) is an underwater mountain located in the Seymour Narrows of the Discovery Passage in British Columbia, Canada. It had two peaks (2.74 metres and 6.4 metres below the surface at low tide) that produced large, dangerous eddies from the strong tidal currents that flowed around them at low tide. Ships transiting the strait preferred to wait until slack tide in order to safely bypass the rock. The hazardous nature of the rock prompted the Canadian government to remove the top of the mountain in a controlled explosion on 5 April 1958. The event was one of the first live coast-to-coast television broadcasts of an event in Canada and was designated a National Historic Event of Canada. Etymology Ripple Rock was so named in 1862 by Captain Richards, RN, because its summits were about at sea level and made a prominent standing wave in the fast tidal current of the strait. History The rock was first noted by explorer George Vancouver in 1791, describ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seymour Narrows
Seymour Narrows is a section of the Discovery Passage in British Columbia known for strong tidal currents. Discovery Passage lies between Vancouver Island at Menzies Bay, British Columbia and Quadra Island except at its northern end where the eastern shoreline is Sonora Island. The section known as Seymour Narrows begins about from the south end of Discovery Passage where it enters the Georgia Strait near Campbell River. For most of the length of the narrows, the channel is about wide. Through this narrow channel, currents can reach . Etymology The narrows were named for Rear Admiral Sir George Francis Seymour who commanded the Pacific Station from 1844 to 1848. Seymour Narrows was described by Captain George Vancouver as "one of the vilest stretches of water in the world." Even after Ripple Rock was removed, it remains a challenging route. In March 1981, the freighter ''Star Philippine'' ran aground in the narrows. Hydrology Seymour Narrows is notable also because the flowi ...

List Of The Largest Artificial Non-nuclear Explosions
There have been many extremely large explosions, accidental and intentional, caused by modern high explosives, boiling liquid expanding vapour explosions (BLEVEs), older explosives such as gunpowder, volatile petroleum-based fuels such as gasoline, and other chemical reactions. This list contains the largest known examples, sorted by date. An unambiguous ranking in order of severity is not possible; a 1994 study by historian Jay White of 130 large explosions suggested that they need to be ranked by an overall effect of power, quantity, radius, loss of life and property destruction, but concluded that such rankings are difficult to assess. The weight of an explosive does not directly correlate with the energy or destructive impact of an explosion, as these can depend upon many other factors such as containment, proximity, purity, preheating, and external oxygenation (in the case of thermobaric weapons, gas leaks and BLEVEs). In this article, explosion means "the sudden conversio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nitramex And Nitramon Explosives
Nitramex and Nitramon Explosives are compositions of various chemical compounds. They are explosives based on ammonium nitrate, with other ingredients such as paraffin wax, aluminum and dinitrotoluene. The inclusion of these additional ingredients creates a more stable explosive. Nitramex and Nitramon have in modern times been replaced by more advanced high explosives based on ammonium nitrate, such as ANFO. Nitramon A typical nitramon formula contains approximately 92 percent ammonium nitrate, 4 percent dinitrotoluene and 4 percent paraffin wax. Nitramex Nitramex has much the same formula as nitramon but with the addition of trinitrotoluene (TNT). This explosive was used in the removal of Ripple Rock Ripple Rock (french: Roche Ripple) is an underwater mountain located in the Seymour Narrows of the Discovery Passage in British Columbia, Canada.
