ANCHORAGE, Alaska (AP) — The alert level for a remote Alaska volcano has been raised again after scientists found another lava dome has formed in the crater in the last week.
阿拉斯加安克雷奇（美聯社） - 偏遠阿拉斯加火山的警戒級別已被提升，在科學家們發現另一個熔岩穹丘上週已在火山口形成後。
The Alaska Volcano Observatory on Wednesday increased the level for Cleveland Volcano, a 5,675-foot peak on uninhabited Chuginadak Island about 940 miles southwest of Anchorage.
阿拉斯加火山觀測站週三增加克利夫蘭火山的水平，那是在無人居住Chuginadak島上的一座5,675英尺高峰，在安克雷奇西南約940英里。
The status was raised earlier this year when the center detected two small, likely ash-poor eruptions through March 13, but lowered the alert level last week after 10 days of inactivity.
今年早些時候狀態曾被提升，當中心檢測到兩個細小、可能是少灰的爆發直到3月13日，但在上週下調警戒級別後閒置超過10天。
Scientists can't actively monitor the volcano because there is no real-time seismic monitoring network on the volcano in the Aleutian Islands.
科學家們不能積極監察火山，因為在阿留申群島的火山上沒有實時的地震監測網絡。
Authorities say sudden eruptions could occur at any time, and ash clouds 20,000 feet above sea level are possible.
當局說，突然的爆發可能隨時發生，及可能有海拔20,000英尺的火山灰雲。
