Loma Prieta Peak
Loma Prieta (from Spanish ''loma'' -hill, ''prieta'' -dark) is high and is the highest peak in the Santa Cruz Mountains in Northern California. Although the 1989 Loma Prieta earthquake was named for this mountain, the actual epicenter was five miles southwest of the peak, across the San Andreas fault, in the The Forest of Nisene Marks State Park. In the 19th century, the peak was called Mount Bache, a name given in honor of Alexander Dallas Bache; the name is no longer in use. From 1955 to 2005, the mountain was the longtime site for the transmitter tower of San Jose television station KNTV. In September 2005, it moved its transmitter northwest to San Bruno Mountain after it became the Bay Area's NBC affiliate. Geology Loma Prieta is the tallest peak in the Santa Cruz Mountains and it is common to see snow on the mountain during the winter. Loma Prieta and other nearby mountain peaks are pushed upward by local collision forces associated with a left bend in the San An ...

Spanish (language)
Spanish ( or , Castilian) is a Romance language of the Indo-European language family that evolved from colloquial Latin spoken on the Iberian peninsula. Today, it is a global language with more than 500 million native speakers, mainly in the Americas and Spain. Spanish is the official language of 20 countries. It is the world's second-most spoken native language after Mandarin Chinese; the world's fourth-most spoken language overall after English, Mandarin Chinese, and Hindustani (Hindi-Urdu); and the world's most widely spoken Romance language. The largest population of native speakers is in Mexico. Spanish is part of the Ibero-Romance group of languages, which evolved from several dialects of Vulgar Latin in Iberia after the collapse of the Western Roman Empire in the 5th century. The oldest Latin texts with traces of Spanish come from mid-northern Iberia in the 9th century, and the first systematic written use of the language happened in Toledo, a prominent city of the ...

Mountains Of Santa Clara County, California
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Monterey Bay
Monterey Bay is a bay of the Pacific Ocean located on the coast of the U.S. state of California, south of the San Francisco Bay Area and its major city at the south of the bay, San Jose. San Francisco itself is further north along the coast, by about 75 miles, accessible via Highway 1 and Highway 280. Santa Cruz is located at the north end of the bay, and Monterey is on the Monterey Peninsula at the south end. The "Monterey Bay Area" is a local colloquialism sometimes used to describe the whole of the Central Coast communities of Santa Cruz and Monterey counties. Toponymy The first European to discover Monterey Bay was Juan Rodríguez Cabrillo on November 16, 1542, while sailing northward along the coast on a Spanish naval expedition. He named the bay ''Bahía de los Pinos'', probably because of the forest of pine trees first encountered while rounding the peninsula at the southern end of the bay. Cabrillo's name for the bay was lost, but the westernmost point of the penin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Clara Valley
The Santa Clara Valley is a geologic trough in Northern California that extends 90 miles (145 km) south–southeast from San Francisco to Hollister. The longitudinal valley is bordered on the west by the Santa Cruz Mountains and on the east by the Diablo Range; the two coastal ranges meet south of Hollister. The San Francisco Bay borders the valley to the north, and fills much of the northern third of the valley. The valley floor is an alluvial plain that formed in the graben (tectonic depression) between the San Andreas Fault to the west and the Hayward and Calaveras faults to the east. Within the valley and surrounding the bay on three sides are the urban communities of San Mateo County, Santa Clara County, and Alameda County, while the narrow southern reaches of the valley extend into rural San Benito County to Hollister. In practical terms, the central portion of the Santa Clara Valley is often considered by itself, contained entirely within Santa Clara County. The val ...

Messier Marathon
A Messier marathon is an attempt, usually organized by amateur astronomers, to find as many Messier objects as possible during one night. The Messier catalogue was compiled by French astronomer Charles Messier during the late 18th century and consists of 110 relatively bright deep-sky objects (galaxies, nebulae, and star clusters). When and where a marathon is possible The number of Messier objects visible in any one night varies depending on a few factors, including the location of the observer, the duration of daylight and nighttime, and the season (the positions of the Messier objects relative to the Sun varies with the season). Location Because Messier compiled his catalog from a northern latitude, not all of the Messier objects are visible from the southern hemisphere. In particular, M81, M82, M52, and M103 make southern-hemisphere Messier marathons difficult, because they are all located at a declination of 60° north or greater. Although a Messier marathon can be att ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
96P/Machholz
Comet 96P/Machholz or 96P/Machholz 1 is a Short-period comet, short-period sungrazing comet discovered on May 12, 1986, by Amateur astronomy, amateur astronomer Donald Machholz on Loma Prieta peak, in central California using binoculars. On June 6, 1986, 96P/Machholz passed from the Earth. 96P/Machholz last came to perihelion on October 27, 2017, and will next come to perihelion on January 31, 2023. The comet has an estimated diameter of around . 96P/Machholz is unusual among comets in several respects. Other than small SOHO comets, its highly Orbital eccentricity, eccentric 5.29 year orbit has the smallest perihelion distance known among numbered/regular short-period comets, bringing it considerably closer to the Sun than the orbit of Mercury (planet), Mercury. It is also the only known short-period comet with both high orbital inclination and high eccentricity. In 2007, 96P/Machholz was found to be both carbon-depleted and cyanogen-depleted, a chemical composition nearly uniqu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Donald Machholz
Donald Edward Machholz (October 7, 1952 – August 9, 2022) was an American amateur astronomer who was credited with the discovery of 12 comets that bear his name. Personal life and death In 2014, he married photojournalist Michele Machholz. They resided at the Stargazer Ranch in Wikieup, Arizona. Machholz died in the early morning of August 9, 2022, at his home in Wikieup, Arizona, from complications of COVID-19. His obituary at ''Astronomy'' stated, "In the years leading up to his death, Machholz was considered the most prolific visual comet discoverer alive." Career He spent more than 9,000 hours comet hunting in a career spanning over 50 years. These comets include the periodic comets 96P/Machholz, 141P/Machholz, the non-periodic C/2004 Q2 (Machholz) that were visible with binoculars in the northern sky in 2004 and 2005, C/2010 F4 (Machholz), and C/2018 V1 (Machholz-Fujikawa-Iwamoto) In 1985, comet Machholz 1985-e, was discovered using a homemade cardboard telescope ...

Transpression
In geology, transpression is a type of strike-slip deformation that deviates from simple shear because of a simultaneous component of shortening perpendicular to the fault plane. This movement ends up resulting in oblique shear. It is generally very unlikely that a deforming body will experience "pure" shortening or "pure" strike-slip. The relative amounts of shortening and strike-slip can be expressed in the convergence angle alpha which ranges from zero (ideal strike-slip) to 90 degrees (ideal convergence). During shortening, unless material is lost, transpression produces vertical thickening in the crust. Transpression that occurs on a regional scale along plate boundaries is characterized by oblique convergence. More locally, transpression occurs within restraining bends in strike-slip fault zones. Transpressional structures Transpressional shear zones are characterized by an association of structures that suggest zone-normal shortening and zone-parallel shearing. Commonly ...
