近5千名消防人員試圖撲滅加州野火

Firefighters in ((the western U.S. state of)) California say inaccessible, steep terrain and extreme fire behavior are hampering efforts to contain a massive wildfire that is threatening a famous national park.

Nearly 5,000 firefighters are battling the Rim Fire but have had to rely heavily on aircraft to slow the spread of the fire.

The U.S. Forest Service said Friday the massive blaze has swelled to more that 800 square kilometers and consumed about 82,000 hectares of land, including some of Yosemite National Park.

The fire is about one-third contained. Authorities are using an unmanned military Predator drone, similar to those used in Afghanistan, to provide information on new fires they would otherwise not be able to see.

The U.S. Forest Service says firefighters expect to fully contain the Rim Fire by September 20.美國西部加利福尼亞州的消防人員表示，人跡罕至、地勢險峻以及極強的火勢阻礙消防隊員控制大規模野火火勢的努力。這場野火正威脅着一個著名的國家公園。

將近5,000名消防隊員正與這場稱爲“環火”的大火拼搏，可是不得依賴飛機來減緩火勢的蔓延。

美國林務局星期五表示，熊熊的大火波及800多平方公里的地區，燒燬了大約82,000公頃的土地，其中包括優勝美地國家公園的部分地區。

大約三分之一的火勢已經得到控制。當局使用一架類似於美軍在阿富汗使用的無人駕駛的軍機，來提供有關新的火勢的信息，否則他們無法觀察全面的火勢。

美國林務局說，消防隊員預計於9月20號以前能全面控制環火的火勢。
