Anvil firing (also known as anvil launching or anvil shooting) is the practice of firing an anvil into the air with gunpowder.
In the UK, the term refers to a method of testing anvils. Black powder was poured onto the top of the anvil and ignited. If the anvil did not shatter it was deemed safe to use.

The 1700 Cascadia earthquake occurred along the Cascadia subduction zone on January 26, 1700 with an estimated moment magnitude of 8.7–9.2. The megathrust earthquake involved the Juan de Fuca Plate from mid-Vancouver Island, south along the Pacific Northwest coast as far as northern California. The length of the fault rupture was about 1,000 kilometers (620 miles), with an average slip of 20 meters (66 ft).
The earthquake caused a tsunami which struck the west coast of North America and the coast of Japan.

The Pig War was a confrontation in 1859 between the United States and United Kingdom over the British–U.S. border in the San Juan Islands, between Vancouver Island (present-day Canada) and the State of Washington. The Pig War, so called because it was triggered by the shooting of a pig, is also called the Pig Episode, the Pig and Potato War, the San Juan Boundary Dispute and the Northwestern Boundary Dispute. Aside from the death of one pig, this dispute was a bloodless conflict.
The Vancouver Special is an architectural style of residential houses developed in Metro Vancouver, Canada. The style was popular in the 1960s to 1980s due to ability to maximize floor space with relatively cheap construction costs.

Ioannis Phokas (Greek: Ἰωάννης Φωκᾶς), better known by the Spanish translation of his name, Juan de Fuca (born 1536 on the Ionian island of Cefalonia; died there 1602), was a Greek maritime pilot in the service of the King of Spain, Philip II. He is best known for his claim to have explored the Strait of Anián, now known as the Strait of Juan de Fuca, between Vancouver Island (now part of British Columbia, Canada) and the Olympic Peninsula (northwestern Washington state, United States).

The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is an interferometric radio telescope at the Dominion Radio Astrophysical Observatory in British Columbia, Canada which consists of four antennas consisting of 100 x 20 metre cylindrical parabolic reflectors (roughly the size and shape of snowboarding half-pipes) with 1024 dual-polarization radio receivers suspended on a support above them. The antenna receives radio waves from hydrogen in space at frequencies in the 400–800 MHz range. The telescope's low-noise amplifiers are built with components adapted from the cellphone industry and its data are processed using a custom-built FPGA electronic system and 1000-processor high-performance GPGPU cluster. The telescope has no moving parts and observes half of the sky each day as the Earth turns. It has also turned out to be a superior instrument for observing the recently discovered phenomenon of fast radio bursts (FRBs).
CHIME is a partnership between the University of British Columbia, McGill University, the University of Toronto and the Canadian National Research Council's Dominion Radio Astrophysical Observatory. A first light ceremony was held on 7 September 2017 to inaugurate the commissioning phase.
