John Verhoogen
John Verhoogen (born Jean Verhoogen, 1 February 1912, Brussels – 8 November 1993) was a Belgian-American geologist and geophysicist. Verhoogen became ill at age 17 from poliomyelitis, which caused him problems throughout the rest of his life. Nevertheless, he studied mining at the University of Brussels (''Ingénieur des Mines'', degree 1933) and engineering geology at the University of Liège (''Ingénieur-Géologue'', degree 1934). He then went to the US, where he studied at the University of California, Berkeley under Howel Williams. In 1936 he received his doctorate in geology (with thesis ''Geology of Mt. St. Helens, Washington'') from Stanford University, although most of the doctoral work was supervised by Williams at Berkeley. Verhoogen was then at the University of Brussels from 1936 to 1939. During the late 1930s and World War II, he was in the Belgian Congo, where he studied the volcano Nyamuragira and worked on the procurement of strategic mineral resources. From 1947 ...

Aswan Dam
The Aswan Dam, or more specifically since the 1960s, the Aswan High Dam, is one of the world's largest embankment dams, which was built across the Nile in Aswan, Egypt, between 1960 and 1970. Its significance largely eclipsed the previous Aswan Low Dam initially completed in 1902 downstream. Based on the success of the Low Dam, then at its maximum utilization, construction of the High Dam became a key objective of the government following the Egyptian Revolution of 1952; with its ability to better control flooding, provide increased water storage for irrigation and generate hydroelectricity, the dam was seen as pivotal to Egypt's planned industrialization. Like the earlier implementation, the High Dam has had a significant effect on the economy and culture of Egypt. Before the High Dam was built, even with the old dam in place, the annual flooding of the Nile during late summer had continued to pass largely unimpeded down the valley from its East African drainage basin.

Diablo Canyon Power Plant
The Diablo Canyon Power Plant is a nuclear power plant near Avila Beach in San Luis Obispo County, California. Since the permanent shutdown of the San Onofre Nuclear Generating Station in 2013, Diablo Canyon has been the only operational nuclear plant and largest single power station in California. It was the subject of controversy and protests during its construction, with nearly two thousand civil disobedience arrests in a two-week period in 1981. The plant has two Westinghouse-designed 4-loop pressurized-water nuclear reactors operated by Pacific Gas & Electric (PG&E). Together, the twin 1100 MWe reactors produce about 18,000 GW·h of electricity annually (8.6% of total California generation and 23% of carbon-free generation), supplying the electrical needs of more than 3 million people. The plant produces electricity for about 6 cents per kWh, less than the average cost of 10.1 cents per kWh that PG&E paid for electricity from other suppliers in 2014. ...

Earthquake Engineering
Earthquake engineering is an interdisciplinary branch of engineering that designs and analyzes structures, such as buildings and bridges, with earthquakes in mind. Its overall goal is to make such structures more resistant to earthquakes. An earthquake (or seismic) engineer aims to construct structures that will not be damaged in minor shaking and will avoid serious damage or collapse in a major earthquake. Earthquake engineering is the scientific field concerned with protecting society, the natural environment, and the man-made environment from earthquakes by limiting the seismic risk to socio-economically acceptable levels. Traditionally, it has been narrowly defined as the study of the behavior of structures and geo-structures subject to seismic loading; it is considered as a subset of structural engineering, geotechnical engineering, mechanical engineering, chemical engineering, applied physics, etc. However, the tremendous costs experienced in recent earthquakes have led t ...

Olema, California
Olema (Miwok: ''Olemaloke'') is an unincorporated community in Marin County, California. It is located on Olema Creek south-southeast of Point Reyes Station, at an elevation of 69 feet (21 m). Olema is along State Route 1 at its intersection with Sir Francis Drake Boulevard, on the eastern edge of the Point Reyes Peninsula in the western part of Marin County. The name Olema comes from the Coast Miwok placename meaning "coyote valley". Olema was once thought to be the epicenter of the 1906 San Francisco earthquake due to the huge fault rifts still visible via a nearby hiking path. There are historical references to this in and around the town, including at shops and restaurants. However, more recent evidence suggests that a location near Daly City is more likely the epicenter. Olema was also the title subject of the late-1960s country-rock song, "Hippie from Olema", The Youngbloods' rejoinder to Merle Haggard's "Okie from Muskogee". The Olema post office opened in 1859, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daly City, California
Daly City () is the second most populous city in San Mateo County, California, United States, with population of 104,901 according to the 2020 census. Located in the San Francisco Bay Area, and immediately south of San Francisco (sharing its northern border with almost all of San Francisco's southern border), it is named for businessman and landowner John Donald Daly. History Archaeological evidence suggests the San Francisco Bay Area has been inhabited as early as 2700 BC. People of the Ohlone language group probably occupied Northern California from at least the year A.D. 500. Though their territory had been claimed by Spain since the early 16th century, they would have relatively little contact with Europeans until 1769, when, as part of an effort to colonize Alta California, an exploration party led by Don Gaspar de Portolá learned of the existence of San Francisco Bay. Seven years later, in 1776, an expedition led by Juan Bautista de Anza selected the site f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1906 San Francisco Earthquake
At 05:12 Pacific Standard Time on Wednesday, April 18, 1906, the coast of Northern California was struck by a major earthquake with an estimated moment magnitude of 7.9 and a maximum Mercalli intensity of XI (''Extreme''). High-intensity shaking was felt from Eureka on the North Coast to the Salinas Valley, an agricultural region to the south of the San Francisco Bay Area. Devastating fires soon broke out in San Francisco and lasted for several days. More than 3,000 people died, and over 80% of the city was destroyed. The events are remembered as one of the worst and deadliest earthquakes in the history of the United States. The death toll remains the greatest loss of life from a natural disaster in California's history and high on the lists of American disasters. Tectonic setting The San Andreas Fault is a continental transform fault that forms part of the tectonic boundary between the Pacific Plate and the North American Plate. The strike-slip fault is characterize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
