For the curious, these were the east harlem and east village gas explosions in 2014 and 2015 respectively. But those are 2 of the 19 events in the wikipedia list of structural collapses in New York, which seems to go back to the 1800s:
给好奇的人补充一下，这分别指的是 2014 年的 east harlem 和 2015 年的 east village 燃气爆炸。不过，这只是 Wikipedia 上 New York 建筑坍塌事件列表中的 19 起事件里的 2 起，而那个列表似乎可以一直追溯到 1800 年代：
When I was living in New York, one building in my friend's neighborhood collapsed. The next year a building near me collapsed. This left me with the impression that buildings did just collapse somewhat regularly in New York. Turns out that's not actually the case, which is good.
我住在 New York 的时候，我朋友所在街区有一栋楼塌了。第二年，我附近又有一栋楼塌了。这让我留下了一种印象：在 New York，楼房似乎确实会比较规律地坍塌。后来发现其实并不是这样，这倒是件好事。
