Field Act
The Field Act was one of the first pieces of legislation that mandated earthquake-resistant construction (specifically for schools in California) in the United States. The Field Act had its genesis in the 6.4 magnitude 1933 Long Beach earthquake which occurred on March 10 of that year and destroyed or rendered unsafe 230 school buildings in Southern California. Many school buildings had completely collapsed due to unreinforced masonry construction and/or shoddy workmanship. The earthquake occurred at 5:55pm on a Friday, several hours after school had let out. Had the earthquake occurred while school was in session earlier that afternoon, thousands of casualties, mainly children, would have likely occurred. Public awareness of this narrowly averted tragedy led to passage of the Act within 30 days of the quake by the California State Legislature. The Act was named after California Assemblyman Charles Field, the key sponsor of the legislation. The act was based on the research done ...

1933 Long Beach Earthquake
The 1933 Long Beach earthquake took place on March 10 at south of downtown Los Angeles. The epicenter was offshore, southeast of Long Beach, California, on the Newport–Inglewood Fault. The earthquake had a magnitude estimated at 6.4 , and a maximum Mercalli intensity of VIII (''Severe''). Damage to buildings was widespread throughout Southern California. It resulted in 115 to 120 fatalities and an estimated $40 million worth of property damage, equivalent to $ million in . The majority of the fatalities resulted from people running out of buildings exposing themselves to the falling debris. Damage Major damage occurred in the densely populated city of Long Beach on the south-facing coast of Los Angeles County. However, the damage was also found in the industrial area south of downtown Los Angeles. An estimated 75,000 mi3 area was impacted, being felt as far as San Joaquin Valley, Owens Valley, and Northern Baja California. The magnitude of the earthquake is conside ...

1940 El Centro Earthquake
The 1940 El Centro earthquake (or 1940 Imperial Valley earthquake) occurred at 21:35 Pacific Standard Time on May 18 (05:35 UTC on May 19) in the Imperial Valley in southeastern Southern California near the international border of the United States and Mexico. It had a moment magnitude of 6.9 and a maximum perceived intensity of X (''Extreme'') on the Mercalli intensity scale. It was the first major earthquake to be recorded by a strong-motion seismograph located next to a fault rupture. The earthquake was characterized as a typical moderate-sized destructive event with a complex energy release signature. It was the strongest recorded earthquake to hit the Imperial Valley, and caused widespread damage to irrigation systems and led to the deaths of nine people. Tectonic setting The Salton Trough is part of the complex plate boundary between the Pacific Plate and the North American Plate where it undergoes a transition from the continental transform of the San Andreas Fa ...

List Of Earthquakes In California
The earliest known California earthquake was documented in 1769 by the Spanish explorers and Catholic missionaries of the Portolá expedition as they traveled northward from San Diego along the Santa Ana River near the present site of Los Angeles. Ship captains and other explorers also documented earthquakes. As Spanish missions were constructed beginning in the late 18th century, earthquakes records were kept. After the missions were secularized in 1834, records were sparse until the California Gold Rush in the 1840s. From 1850–2004, there was about one potentially damaging event per year on average, though many of these did not cause serious consequences or loss of life. Since the three damaging earthquakes that occurred in the American Midwest and the East Coast ( 1755 Cape Ann, 1811–12 New Madrid, 1886 Charleston) were well known, it became apparent to settlers that the earthquake hazard was different in California. While the 1812 San Juan Capistrano, 1857 Fort Tejon, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Community College
A community college is a type of educational institution. The term can have different meanings in different countries: many community colleges have an "open enrollment" for students who have graduated from high school (also known as senior secondary school or upper secondary school). The term usually refers to a higher educational institution that provides workforce education and college transfer academic programs. Some institutions maintain athletic teams and dormitories similar to their university counterparts. Australia In Australia, the term "community college" refers to small private businesses running short (e.g. 6 weeks) courses generally of a self-improvement or hobbyist nature. Equivalent to the American notion of community colleges are Tertiary and Further Education colleges or TAFEs; these are institutions regulated mostly at state and territory level. There are also an increasing number of private providers colloquially called "colleges". TAFEs and other provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
K–12
K–12, from kindergarten to 12th grade, is an American English expression that indicates the range of years of publicly supported primary and secondary education found in the United States, which is similar to publicly supported school grades before college in several other countries, such as Afghanistan, Australia, Canada, China, Ecuador, Egypt, India, Iran, the Philippines, South Korea, and Turkey. History U.S. public education was conceived of in the late 18th century. In 1790, Pennsylvania became the first state to require some form of free education for everyone regardless of whether they could afford it. New York passed similar legislation in 1805. In 1820, Massachusetts became the first state to create a tuition-free high school, Boston English. The first K–12 public school systems appeared in the early 19th century. In the 1830s and 1840s, Ohioans were taking a significant interest in the idea of public education. At that point in time, schools were commonly ope ...

Architect
An architect is a person who plans, designs and oversees the construction of buildings. To practice architecture means to provide services in connection with the design of buildings and the space within the site surrounding the buildings that have human occupancy or use as their principal purpose. Etymologically, the term architect derives from the Latin ''architectus'', which derives from the Greek (''arkhi-'', chief + ''tekton'', builder), i.e., chief builder. The professional requirements for architects vary from place to place. An architect's decisions affect public safety, and thus the architect must undergo specialized training consisting of advanced education and a ''practicum'' (or internship) for practical experience to earn a license to practice architecture. Practical, technical, and academic requirements for becoming an architect vary by jurisdiction, though the formal study of architecture in academic institutions has played a pivotal role in the development of t ...

Engineer
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year Bachelor of Engineering, bachelor's degree in an engineering discipline, or in some jurisdictions, a Master of Engineering, master's degree in an engineering discipline plus ...
