Fires continue to rage all across California in blazes that have so far killed 31 while displacing hundreds of thousands more, and several organizations have put out a call for help.

While fires are raging all round the state, the two largest at this time are the Camp Fire north of Sacramento, which has claimed at least 29 lives and is considered the most destructive fire in state history; and the Southern California Woolsey Fire near Los Angeles, which has killed two and required the evacuation of over 250,000.

Meanwhile, other fires continue their destruction as far north as the Oregon border and as far south as just outside San Diego.

Money is the preferred way to support, say those on the ground.

"During a natural disaster with constant images of destruction on television and social media, public reaction is to want to help, and we are so grateful for that support,'' sheriff's Chief Maria Gutierrez, who is also director of the Los Angeles County Emergency Operations Center, told NBC Los Angeles. "The easiest and most effective way to get support to those who need it most is to donate to organizations offering direct assistance."
