Damage in Armenia, Colombia, for the 25 January 1999 (Mw=6.2, peak ground acceleration (PGA) 580 Gal) event was disproportionate. We analyze the damage report as a function of number of stories and construction age of buildings. We recovered two vulnerability evaluations made in Armenia in 1993 and in 2004. We compare the results of the 1993 evaluation with damage observed in 1999 and show that the vulnerability evaluation made in 1993 could have predicted the relative frequency of damage observed in 1999. Our results show that vulnerability of the building stock was the major factor behind damage observed in 1999. Moreover, it showed no significant reduction between 1999 and 2004.

亚美尼亚(哥伦比亚)地震灾害中的脆弱性和场地影响——第 2 部分:观察到的破坏和脆弱性

1999 年 1 月 25 日,哥伦比亚亚美尼亚(M w = 6.2,峰值地面加速度 (PGA) 580 Gal)事件的破坏程度不成比例。我们将损坏报告作为楼层数和建筑物建造年限的函数进行分析。我们恢复了 1993 年和 2004 年在亚美尼亚进行的两次脆弱性评估。我们将 1993 年评估的结果与 1999 年观察到的损害进行了比较,并表明 1993 年进行的脆弱性评估可以预测 1999 年观察到的损害的相对频率。我们的结果表明建筑存量的脆弱性是 1999 年观察到的损坏背后的主要因素。此外,在 1999 年至 2004 年之间没有显着减少。
