Silicon Valley was primarily an agricultural center from the time of California's founding until World War II. During and after the war, working and middle class families migrated to the area to settle and work in the burgeoning aerospace and electronics industries. The South Bay Area experienced rapid growth as agriculture was gradually replaced by high-technology. During this period, the Santa Clara Valley gradually became an urbanized metropolitan region. Today, the growth continues, fueled primarily by technology jobs, the weather, and immigrant labor. Urbanization is gradually replacing suburbanization as the population density of the valley increases. This trend has resulted in a huge increase in property values, forcing many middle class families out of the area or into lower income neighborhoods in older sections of the region. The Santa Clara Valley also came to be known as Silicon Valley, as the area became the premier technology center of the United States. Some notable tech companies headquartered in the South Bay are

s. The areas near the Pacific Ocean are generally characterized by relatively small temperature variations during the year, with cool foggy summers and mild rainy winters. Inland areas, especially those separated from the ocean by hills or mountains, have hotter summers and colder overnight temperatures during the winter. San Jose at the south end of the Bay averages fewer than 15 inches (381 mm) of rain annually, while Napa at the north end of the Bay averages over 30 and parts of the Santa Cruz Mountains just a few miles west of San Jose get over 55. In the summer, inland regions can be over 40 degrees Fahrenheit (22 degrees Celsius) warmer than the coast. This large temperature contrast induces a strong pressure gradient, which results in brisk coastal winds which help keep the coastal climate cool and typically, foggy during the summer. Additionally, strong winds are produced through gaps in the coastal ranges such as the

Earthquakes
The region is particularly exposed to hazards associated with large earthquakes, owing to a combination of factors:
- Numerous major active faults in the region.
- A combined thirty year probability of a major earthquake in excess of seventy percent.
- Poorly responding native soil conditions in many places near the bay and in inland valleys, soils which amplify shaking as shown in the map to the right.
- Large areas of filled marshlands and bay mud that are significantly urbanized, with most subject to liquefaction, becoming unable to support structures.
- A large inventory of older buildings, many of which are expected to perform poorly in a major earthquake.
- Extensive building in areas subject to landslide

, mudslide, and in some locations directly over active fault surface rubble zones.
- Most lowrise construction is not fireproof and water systems are likely to be extensively damaged and so large areas are subject to destruction by fire after a large earthquake.

bypasses constructed to handle flooding. While quite expensive, the restoration of a natural environment is of high priority in the intensively urbanized areas of the region.
Windstorms and wildfires
Typically between late November and early March, a very strong Pacific storm can bring both substantial rainfall (saturating and weakening soil) and strong wind gusts that can cause trees to fall on power lines. Owing to the wide area involved (sometimes hundreds of miles of coast), service can be interrupted for up to several days in some more remote localities, but service is usually restored quickly in urban areas. These storms occasionally bring lightning & thunder. More rarely they even spawn tornadoes. For example, during the abnormal hurricane-like storm in early 2010, a funnel cloud sparked an extremely rare Tornado Warning in Morgan Hill.
