作为地质工作者，我熟知地球的力量，但看到这样的恐怖场景，仍然感到头皮发麻和不可思议。

नेपाल त्रासदी का वो वीडियो जो पहले सोशल मीडिया पर अपलोड नहीं हुआ था ।

कल एक मीडिया पोर्टल Nepal7 द्वारा सोशल मीडिया पेज पर अपलोड किया गया है कैसे कुछ मिनटो में सब कुछ तबाह हुआ इस वीडियो में देखे खौफनाक मंजर।

@Tweeterricola 不应高估公众对冰川科学的认知水平。我是地球科学科普工作者，经常接触参与气候变暖讨论的互联网用户。我发现，他们中很多人不知道冰川不会因季节变化而出现面积显著改变、不会因季节变化出现肉眼可见的流速变化的人。他们中的很多人，甚至不能区分积雪和冰川。

#Krakatau: iniziano ad arrivare i primi filmati dopo il violento parossismo degli scorsi giorni. Da quel poco che si riesce a vedere, una parte dell'isola centrale di Anak Krakatau è stata distrutta.

This is what a Jurassic forest may have sounded like.

By combining exquisitely preserved fossil wings with experiments on living insects, computer simulations, and machine learning, scientists have re-created what they say is a partial Middle Jurassic soundscape.

If the reconstruction is correct, one of the insect calls would be the oldest known evidence of ultrasonic communication in animals—long before echolocating bats appeared.

@realzhimo @ChGefaell 目前同样没有证据支持这一点。对于构造活跃的高山冰冻圈，这样的失稳岩体存在的时代会非常漫长。

和卫星比对，画面里的河流峡谷确实是位于吉隆口岸东侧的东林藏布峡谷，地貌和河流形态都属实。但目前尚无法确认画面是真实实拍，还是AI合成。考虑到口岸尼泊尔一侧同样没有人员和建筑幸存，流出实拍画面的可能性很底。但即便是AI生成，它确实也符合在场人士在生命的最后一刻看见的恐怖景象……R.I.P.

This photo was recently shared by Chinese media. It is from Lende Khola, where the huge flood happened.

The photo was taken about 1 kilometer before the flood reached the Rasuwagadhi border. You can see how high and powerful the flood was. 🌊

Same relaxing sounds, different photo. This is what a Jurassic forest may have sounded like.

@MatthewWielicki While the inherent instability and failure of the mountain mass itself may have been the predominant factor in this specific incident, excessively rapid glacial melting at least constitutes a significant contributing factor that exacerbates slope destabilization.

[云舞空城 @cloudycitycat]

@MatthewWielicki 但无论首先发生的是冰川崩塌还是山体崩塌，全球变暖引起的冰川剧烈消融后退有助于促进山体崩塌，这早已是科学界承认的事实。也许本次事件中，山体本身失稳崩塌的因素更大，但是冰川过快消融至少是一个显著的促进山体失稳的因素。

[云舞空城 @cloudycitycat]

@MatthewWielicki Nevertheless, regardless of which event—the glacial collapse or the mountain collapse—initiated the sequence, it is a widely acknowledged scientific consensus that drastic glacial ablation and retreat, driven by global warming, facilitate mountain slope failures.

[云舞空城 @cloudycitycat]

@MatthewWielicki More detailed seismic data reveal that, prior to the major mountain collapse at 10:52 Beijing Time, successive small-scale failures had been occurring sequentially from just after 08:00; however, no evidence is currently available to ascertain the nature of these precursor events

[云舞空城 @cloudycitycat]

@MatthewWielicki English version if needed: Although the collapsed material consists predominantly of bedrock from the mountain mass rather than glacial ice, current evidence does not definitively indicate whether a glacier collapse or a bedrock slope failure occurred first.
