The world’s second-tallest tsunami wave on record tore through the remoteTracy Arm fjord in Alaskalast August, leaving immense destruction in its wake.Luckily, there were no people nearby. But in its aftermath, scientists immediately went to work, piecing together what happens when a mountainside collapse kicks off a mega-tsunami and no one is around to see it.This is how it happened: On August 10, at 5:30 in the morning, an entire mountainside at the mouth of the receding South Sawyer glacier detached, falling into the ocean and producing a monster wave. At its peak, the wave raced up over 1,500 feet on the opposing wall of the fjord — a height taller than Kuala Lumpur’s twin Petronas towers.The mega-tsunami wreaked havoc across the landscape, stripping forests down to bare rock, ripping trees out by their roots and hurling boulders.⛅ Get CNN Weather in your inboxThe forecast is just the beginning.

Only thesecond timethat an effect like this has been recorded anywhere, it was caused by trapped energy from the wave sloshing around in the fjord for days following the initial event.In the months following the tsunami, a dozen scientists from the US, Canada and Europe have been doing “detective” work, attempting to “re-create this hazards cascade,” said Daniel Shugar, a geomorphologist and professor at the University of Calgary.Scientists see the fingerprints of climate change all over this event and several others like it that have occurred in recent years. Many of them have been linked to retreating glaciers, as melting ice destabilizes the mountains and land that had been covered for centuries.“As the climate is changing, as glaciers are retreating, we are likely going to see more of these kinds of events in high latitude environments in the Arcti

去年八月，世界上有记录以来第二高的海啸席卷了阿拉斯加偏远的特雷西湾峡湾，留下了巨大的破坏。幸运的是，附近没有人。但灾难发生后，科学家们立即开始工作，拼凑出当山坡崩塌引发大海啸而周围无人看到时会发生什么。事情是这样的：8月10日凌晨5点30分，南索耶冰川消退口处的整个山坡发生了塌陷。
