The 1959 Hengchun earthquake (Chinese: 1959年恆春地震; pinyin: 1959 nián Héngchūn dìzhèn) was a magnitude 7.1 earthquake which struck the southern tip of Taiwan on August 15, 1959. It was the tenth deadliest earthquake in twentieth century Taiwan, killing 16 or 17 people.[1]
Technical details
editThe earthquake occurred at 16:57 CST on Saturday August 15, 1959, with an epicentre 50 kilometres (31 mi) east-southeast of Oluanpi, the southern tip of the island of Taiwan. The tremor measured 7.1 on the Richter scale and had a focal depth of 20 kilometres (12 mi). A tsunami 4–5 metres high resulting from the quake hit both the southeastern and southwestern coasts of Hengchun. The earthquake was felt throughout Taiwan and also in the Penghu islands off Taiwan's western coast.[2]
Damage
editAccording to Taiwan's Central Weather Bureau the casualties and damage were as follows:[2]
- 17 dead
- 33 seriously injured
- 35 lightly injured
- 1,214 dwellings completely destroyed
- 1,375 dwellings partially destroyed
Due to Hengchun's exposed position on the southern tip of Taiwan, residents frequently built heavy houses of stone to counter both the effects of typhoons and the seasonal northwesterly monsoon winds. These structures effectively resisted the effects of wind, but fared poorly in earthquakes, collapsing and trapping the occupants.[2]
Fortunately the timing of the quake, late afternoon, meant that many people were outdoors when it struck, lessening casualties from building collapse. The estimated cost of the damage (in 1959 New Taiwan Dollars) was NT$24,111,920 for private housing, and NT$6,127,000 for damaged or collapsed school buildings, giving a total of just over NT$30m.[2]
