PIEQF
The ''Parkfield Interventional EQ Fieldwork'' also known as ''PIEQF'' can be seen as the seminal work of New Zealand born installation and performance artist D.V. Rogers. This early 21st century example of land art was installed temporarily in the remote township of Parkfield, Central California. A geologically interactive installation, this machine earthwork operated autonomously for a total of 91 days between 18 August and 16 November 2008. An earthquake shaking table was used in this seismic art intervention which was controlled by realtime reported Californian earthquakes detected by the US Geological Survey seismic monitoring network. Construction Rogers selected the location of Parkfield for its significance as the most densely monitored earthquake region in the world. USGS Seismologist Andy Micheal originally suggested the location. Parkfield is also the home of the USGS Parkfield Earthquake Experiment and the San Andreas Fault Observatory at Depth (SAFOD).

Land Art
Land art, variously known as Earth art, environmental art, and Earthworks, is an art movement that emerged in the 1960s and 1970s, largely associated with Great Britain and the United StatesArt in the modern era: A guide to styles, schools, & movements. Abrams, 2002. (U.S. edition of Styles, Schools and Movements, by Amy Dempsey) but that also includes examples from many countries. As a trend, "land art" expanded boundaries of art by the materials used and the siting of the works. The materials used were often the materials of the Earth, including the soil, rocks, vegetation, and water found on-site, and the sites of the works were often distant from population centers. Though sometimes fairly inaccessible, photo documentation was commonly brought back to the urban art gallery.http://www.land-arts.com Land art. Concerns of the art mov ...

Parkfield, California
Parkfield (formerly Russelsville) is an unincorporated community in Monterey County, California. It is located on Little Cholame Creek east of Bradley, at an elevation of . As of 2007, road signs announce the population as 18. Parkfield is located in the Temblor Range between the San Joaquin Valley and the Central Coast, at an elevation of above sea level. Mining and homesteading used to be prosperous activities in this community, but the mines were exhausted below economic recovery levels, and the industry moved elsewhere. Today, Parkfield is a small town of about 18 people, most of whom are ranchers and farmers. There is a small tourism industry in the town based on equine-related events, hunting, a bluegrass music festival, and Parkfield's unique earthquake history (see the Geology section below). The Parkfield motto is, "Be here when it happens." A post office operated at Parkfield from 1884 to 1954. The town's original name of Russelsville was rejected by the post offic ...

Earthquake Shaking Table
There are several different experimental techniques that can be used to test the response of structures and soil or rock slopes to verify their seismic performance, one of which is the use of an earthquake shaking table (a shaking table, or simply shake table). This is a device for shaking scaled slopes, structural models or building components with a wide range of simulated ground motions, including reproductions of recorded earthquakes time-histories. While modern tables typically consist of a rectangular platform that is driven in up to six degrees of freedom (DOF) by servo-hydraulic or other types of actuators, the earliest shake table, invented at the University of Tokyo in 1893 to categorize types of building construction, ran on a simple wheel mechanism. Test specimens are fixed to the platform and shaken, often to the point of failure. Using video records and data from transducers, it is possible to interpret the dynamic behaviour of the specimen Specimen may refer to: ...

Art Intervention
Art intervention is an interaction with a previously existing artwork, audience, venue/space or situation. It has the auspice of conceptual art and is commonly a form of performance art. It is associated with the Viennese Actionists, the Dada movement and Neo-Dadaists. Stuckists have made extensive use of it to affect perceptions of artworks they oppose and as a protest against existing interventions. Intervention can also refer to art which enters a situation outside the art world in an attempt to change the existing conditions there. For example, intervention art may attempt to change economic or political situations, or may attempt to make people aware of a condition that they previously had no knowledge of. Since these goals mean that intervention art necessarily addresses and engages with the public, some artists call their work "public interventions". Although intervention by its nature carries an implication of subversion, it is now accepted as a legitimate form of art a ...

SAFOD
The San Andreas Fault Observatory at Depth (SAFOD) is a research project that began in 2002 aimed at collecting geological data about the San Andreas Fault for the purpose of predicting and analyzing future earthquakes. The site consists of a pilot hole and a main hole. Drilling operations ceased in 2007. Located near the town of Parkfield, California, the project has installed geophone sensors and GPS clocks in a borehole that cuts directly through the fault. This data, along with samples collected during drilling, could shed new light on geochemical and mechanical properties around the fault zone. SAFOD is part of Earthscope, an Earth science program using geological and geophysical techniques to explore the structure of the North American continent and to understand the origin of earthquakes and volcanoes. Earthscope is funded by the National Science Foundation in conjunction with the U.S. Geological Survey and NASA. Data collected at SAFOD are available from The Northe ...

San Andreas Fault
The San Andreas Fault is a continental transform fault that extends roughly through California. It forms the tectonics, tectonic boundary between the Pacific Plate and the North American Plate, and its motion is Fault (geology)#Strike-slip faults, right-lateral strike-slip (horizontal). The fault divides into three segments, each with different characteristics and a different degree of earthquake risk. The slip rate along the fault ranges from /yr. It was formed by a transform boundary. The fault was identified in 1895 by Professor Andrew Lawson of University of California, Berkeley, UC Berkeley, who discovered the northern zone. It is often described as having been named after San Andreas Lake, a small body of water that was formed in a valley between the two plates. However, according to some of his reports from 1895 and 1908, Lawson actually named it after the surrounding San Andreas Valley. Following the 1906 San Francisco earthquake, Lawson concluded that the fault extende ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Webcam
A webcam is a video camera which is designed to record or stream to a computer or computer network. They are primarily used in videotelephony, livestreaming and social media, and security. Webcams can be built-in computer hardware or peripheral devices, and are commonly connected to a device using USB or wireless protocols. Webcams have been used on the Internet as early as 1993, and the first widespread commercial one became available in 1994. Early webcam usage on the Internet was primarily limited to stationary shots streamed to web sites. In the late 1990s and early 2000s, instant messaging clients added support for webcams, increasing their popularity in video conferencing. Computer manufacturers also started integrating webcams into laptop hardware. In 2020, the COVID-19 pandemic caused a shortage of webcams due to the increased number of people working from home. History Early development (early 1990s) First developed in 1991, a webcam was pointed at the Trojan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
