Among the 20 U.S. metropolitan areas with the highest foreclosure rates, foreclosures actually declined in the last year, falling in 14 of the top 20 cities and eight of the top 10, reports RealtyTrac, which provides a market platform for foreclosures.

The decreasing foreclosure activity in some of the nation's top foreclosure hot spots in the first quarter is largely the result of government intervention and other non-market influences, and not a sure signal that those areas are out of the woods yet when it comes to foreclosures, says RealtyTrac CEO James J. Saccacio.

Nationwide, foreclosure activity increased in 159 of the 206 metro areas RealtyTrac tracks and was up 16 percent overall compared to the first quarter of 2009.

Here are the top 10 cities with the most foreclosures:

1. Las Vegas-Paradise, Nev.
2. Modesto, Calif.
3. Cape Coral-Fort Myers, Fla.
4. Riverside-San Bernardino-Ontario, Calif.
5. Stockton, Calif.
6. Merced, Calif.
7. Phoenix-Mesa-Scottsdale, Ariz.
8. Vallejo-Fairfield, Calif.
9. Bakersfield, Calif.
10. Orlando-Kissimmee, Fla.
