The Northridge earthquake occurred at 4:30 a.m. local time on January 17, 1994.

Northridge is located about 19 miles northwest of Los Angeles. This earthquake had a 6.9 moment magnitude.

The hypocentral depth was 11.80 m. The duration was about 10 seconds to 20 seconds. The earthquake occurred along a "blind" thrust fault, close to the San Andreas fault. Note that a blind fault is a fault which does not extend to the surface. In other words, it is buried.

The Northridge earthquake was the worst earthquake in the Los Angeles basin since the San Fernando earthquake in 1971, which had a 6.7 magnitude.


The number of fatalities in the Northridge earthquake was 57. About 9000 people were injured. The fact that the earthquake occurred at 4:30 a.m. minimized the death toll.


The Northridge earthquake caused extensive damage to parking structures and freeway overpasses. For example, a section of the Antelope Valley Freeway collapsed onto the Golden State Freeway south of Newhall. Also, a section of the Santa Monica Freeway in West Los Angeles collapsed.

In addition, a 2500-car parking garage at the California State University at Northridge collapsed.

This structure was about 3 km away from the epicenter. Furthermore, the Northridge earthquake triggered landslides in the Santa Susana Mountains, Santa Monica Mountains, and western San Gabriel Mountains. These landslides blocked roads and damaged water lines.

The landslides also damaged homes, particularly in the Pacific Palisades area. One positive note was that the Olive View Hospital in Sylmar withstood the Northridge earthquake. This hospital had been destroyed by the 1971 San Fernando earthquake.

After its collapse, the hospital was rebuilt to a more exacting seismic code.

Fortunately, the Northridge area has arid, dry soil. Thus, there were few significant liquefaction and ground failure effects. In constrast, soil liquefaction caused massive damage in the 1964 Alaskan and the 1989 Loma Prieta earthquakes.


Thousands of aftershocks occurred after the main earthquake.

For example, a magnitude 5.9 aftershock occurred about 1 minute after the mainshock. A magnitude 5.6 earthquake occurred 11 hours later. Aftershocks are a concern because they can trigger the collapse of structures weakened by the mainshock.

Team members care for thousands of the region's sickest children with heart conditions, including fetuses, newborns, infants, children, adolescents, and adult, long-term patients with pediatric cardiovascular conditions. At Children's families experience coordinated, next-generation care, delivered by a compassionate, multidisciplinary team of leaders in the pediatric cardiology field. One of the largest pediatric cardiovascular programs in the region. Studies have shown that high volumes are associated with high quality and better outcomes, because experience is a major factor in quality of care. Wort was traditionally prescribed in parts of Europe for depression (in addition to use as a general-purpose tea), and Chinese medicine developed elaborate lists of herbs and preparations. With the scientific revolution in Europe and the United States, the use of traditional herbal remedies fell out of favor with the mainstream medical establishment, although a few people continued to use and maintain knowledge of traditional European herblore. In the early 20th century, scientists began reassessing this rejection of traditional herbs in medicine. Vorzüge eines intakten und lebendigen Gemeinschaftslebens bewahren.

Descriptive and quantitative transcriptome analyses are important for interpreting the functional elements of the genome and revealing the molecular constituents of cells and tissues. It is known that sperm function can be affected by ASG proteins, including the processes of capacitation and the acrosome reaction, as well as canadian pharmacy accutane sperm motility, DNA integrity and interaction with the oocyte. BSPs (bovine seminal plasma protein, unigene 64,588 and unigene 69,768), fertilin (unigene 17,270 and unigene 27,136), ACE (Angiotensin converting enzyme, unigene 7,164 and unigene 21,069), GPX5 (glutathione peroxidase, epididymal secretory glutathione peroxidase, unigene15860), Spermadhesin-1 (Acidic seminal fluid protein, aSFP). The reproduction-related transcripts identified in the ASG and testis transcritptomes in E. This interaction of PDC-109 with the sperm cell membrane results in an efflux of cholesterol and choline phospholipids, that appears to be important for capacitation. The main changes in spermatozoa that occur during epididymal maturation are the ability to move, recognize and bind to the ZP, and to fuse with the plasma membrane of the oocyte..

The reasons for this are practical: many individuals in these families have a large number of nevi, and complete removal of them all is not feasible, since new atypical nevi continue to develop. In addition, individuals with increased susceptibility to melanoma may have cancer arise de novo, without a precursor lesion such as a nevus. The disadvantages of screening include the limitations of available noninvasive testing methods and the risks associated with invasive screening procedures.
