- Seattle Neighborhoods: Columbia City — Thumbnail History (historylink.org)
Columbia City, a historic neighborhood in southeast Seattle, began as a townsite developed by promoter J. K. Edmiston, who built an electric rail line from downtown Seattle through the Rainier Valley along the route now followed by Rainier Avenue. It was incorporated as an independent town in 1893 and was annexed into Seattle in 1907. Manufacturers such as the Hitt Fireworks Company and Heater Glove Company sustained the local economy until World War II, when the neighborhood became home to defense workers and Hitt Fireworks switched to military production. Columbia City saw declines in the post-war years, reaching a nadir in the late 1970s when crime was a major concern and many storefronts were empty. In subsequent decades, a combination of public and private efforts helped revitalize the area. The local business community won Landmark District status for Columbia City in 1978, helping to preserve the neighborhood’s historic ambience. Once-empty storefronts have become restaurants, offices, an art gallery, and other businesses.
- Easter Microplate (Wikipedia)
Easter Plate is a tectonic microplate located to the west of Easter Island off the west coast of South America in the middle of the Pacific Ocean, bordering the Nazca Plate to the east and the Pacific Plate to the west. It was discovered from looking at earthquake distributions that were offset from the previously perceived Nazca-Pacific Divergent boundary. This young plate is 5.25 million years old and is considered a microplate because it is small with an area of approximately 160,000 square kilometres (62,000 sq mi). Seafloor spreading along the Easter microplate’s borders have some of the highest global rates, ranging from 50 to 140 millimetres (2.0 to 5.5 in)/yr.
