只有当资产离得足够近，足以发生重大震动时，地震才会产生损失。当社区投保高时，大部分损失转移到保险公司。2010-2011年坎特伯雷地震序列中的许多事件都足够浅，靠近（或低于）基督城，使城市遭受非常强烈的震动（V：1.7 g; H：2.2 g）。地震造成了广泛的破坏，城市的环境加剧了地震的破坏，其中东部郊区建在低洼的平地（以前是沼泽）上，液化现象普遍，南部郊区位于现在休眠的利特尔顿/阿卡罗阿火山的侧翼，经历了巨石滚动和滑坡的影响。有17起事件导致了保险索赔。破坏事件之间的间隔时间不足以对广泛的破坏进行评估或修复。此外，构造沉降和液化喷射物的结合降低了地表，造成了不可接受的洪水风险。本文提供了一个最复杂的保险结算程序的快照经历任何地方。
Earthquakes generate loss only when assets are near enough to be significantly shaken. When communities are highly insured, much of that loss transfers to the insurer. Many events in the 2010–2011 Canterbury Earthquake Sequence were sufficiently shallow and close to (or under) Christchurch to subject the city to very intense shaking (V: 1.7 g; H: 2.2 g). Shaking damage was extensive, exacerbated by the city's setting wherein the eastern suburbs were built on low-lying flatlands (formerly swamp) where liquefaction was widespread, and the southern suburbs, on the flanks of the now-dormant Lyttelton/Akaroa volcano, experienced boulder roll and landslide effects. There were 17 events in the sequence that resulted in insurance claims. The interval between damaging events was insufficient to enable the widespread damage to be assessed or repaired. Furthermore, the combination of tectonic subsidence and liquefaction ejectile lowered the land surface, creating unacceptable flood risk. This paper provides a snapshot of the most complicated insurance settlement program experienced anywhere.
