There was a hum that nobody could hear. It was a seismic event, one that originated off the coast of Mayotte on Nov. 11, a tiny island in the waters between Madagascar and Mozambique.

那是一段沒人能聽見的嗡嗡聲。它是一次地震事件,1111日發生在馬約特島的海岸周遭,這座小島位於馬達加斯加島、莫三比克之間的海域。

 

The hum, National Geographic reported, was strange for a number of reasons. First, it rang at just a single ultra-low frequency, like a well-tuned bell. Second, the wave emerged and circled the planet without the usual signs of an earthquake; no one in the area felt any shaking. And yet, a Nov. 12 report from the French government found that Mayotte had slid 2.4 inches6 centimetersto the east and 1.2 inches3 cmto the south.

國家地理雜誌報導,這段嗡嗡聲的不尋常之處很多。首先,它只包含一段超級低頻波,宛如純律鐘聲。再者,震波產生後傳至全球,卻沒有出現地震的一般現象;震央地區沒有人感覺到地表發生任何晃動。而法國政府1112日發布的報告顯示,馬約特島已經往東滑動2.4吋(6公分)、往南滑動1.2吋(3公分)。

 

Scientists have proposed a number of possible explanations for the strange seismic event near Mayotte. But none is yet anywhere near confirmed.

科學家已經提出許多針對馬約特島奇怪地震事件的可能解釋。但至今沒有任何假說獲得證實。

 

Perhaps a "slow earthquake" struck the area, the sort that doesn’t cause much intense shaking because it occurs over a much longer period of time. Perhaps a bubble of magma squeezed past below the surface. Researchers even speculated about a meteor strike, though that seems unlikely. For now, the exact cause remains a mystery.

或許是「慢地震」襲擊該地區,這類地震不會引起劇烈搖晃,因為它的發震持續時間較長。也或許是有岩漿氣泡擠壓過地表之下。研究人員甚至猜測是隕石撞擊,儘管看起來不大可能。直到現在,該次地震事件的確切成因仍是個謎團。
