>The 1556 Shaanxi earthquake (Postal romanization: Shensi), known in Chinese colloquially by its regnal year as the Jiajing Great Earthquake "嘉靖大地震" (Jiājìng Dàdìzhèn) occurred in the early morning of 23 January 1556 in Huaxian, Shaanxi during the Ming dynasty. >Most of the residents there lived in yaodongs—artificial caves in loess cliffs—which collapsed and buried alive those sleeping inside. Modern estimates put the direct deaths from the earthquake at over 100,000, while over 700,000 migrated away or died from famine and plagues, which summed up to a total loss of 830,000 people in Imperial records.[3][4][5] It was the deadliest recorded earthquake in history, and in turn one of the deadliest natural disasters in Chinese history.[6] https://en.wikipedia.org/wiki/1556_Shaanxi_earthquake https://en.wikipedia.org/wiki/1556_Shaanxi_earthquake You might also ask people in Turkey, where at least 50,000 people have died so far, what they think of masonry structures.
