澳大利亞野外驚現神祕SOS求救信號

An SOS signal made of rocks in a remote part of Western Australia has prompted fears that someone, or more than one person, could be missing.

近日，西澳大利亞偏遠地區發現了一個由石頭堆成的SOS信號，人們擔心可能不止一個人失蹤了。

The distress signal was spotted by a helicopter pilot. It led to a ground search by police who had to reach the area by air because of tough terrain.

該求救信號是被一名直升機飛行員發現的。隨後警方展開地面搜查，由於地勢艱難，警察必須乘飛機到達該地區。

Authorities have now appealed for public help after failing to find "any indication of recent human activity".

在沒有找到“任何近期人類活動跡象”後，有關部門現在已經呼籲公衆幫忙。

However, police said they had discovered the remains of a campsite at the scene, which is at Swift Bay about 500km (300 miles) from the city of Broome.

但是警方表示，他們發現現場--就在距離布魯姆市約500公里（300英里）處的斯威夫特灣有露營的痕跡。

"Police are trying to establish if there are any missing persons in the area who require assistance," they said in a statement.

警方在一則聲明中稱：“我們正在設法確定該地區是否有任何需要援助的失蹤人員。”

Senior Sgt Peter Reeves told the Australian Broadcasting Corp that the message may have been there for years.

警長彼得·裏弗斯向澳大利亞廣播公司透露，這個信號可能已經在那兒好幾年了。

"There are indications that there may have been someone camped there at one point in time, but it is just not clear how long ago that was," he said.

他表示：“有跡象表明，可能有人在那裏露營過，但是不清楚是多久以前的。”
