At least 300 homes were evacuated as a result of fast-moving wildfire in California, CBS reported.

The blaze that started Monday on the southern edge of Santa Clara County quickly spread to 500 acres, threatening radio and television antennas, California Department of Forestry and Fire Protection spokeswoman Stephanie Stuehler said.

About 200 fire officers and ten units of air equipment were fighting against the fire in the Santa Cruz Mountains.

Causes of the wildfire are under investigation.
