2016年4月16日，震中位于马纳比北部穆伊斯内东南偏南29公里处的Mw7.8级地震造成约 700人死亡，3万人受伤，Pedernales、Portoviejo、Canoa、Bahia de 卡拉基斯和曼塔，其中大多数是厄瓜多尔沿海的重要旅游中心。在5月24日至6月7日期间，一支队伍 由地震工程实地勘探队(EEFIT)部署，目的是调查破坏情况和 记录观察结果，帮助科学和专业人士了解这一事件及其 后果。该团队是这篇论文的所有合著者，他们调查了结构破坏模式，调查了1332座建筑， 验证了从卫星图像获得的30个地点的滑坡数据，并在3个避难所采访了120户家庭。损害 在低层和中层建筑中观察到的光谱响应似乎与在曼塔、波托维耶霍、 还有佩德纳莱斯。卫星滑坡识别在80%-90%的调查案例中被证明是有效的。这个 根据我们有限的调查，在受影响的人群中，失业率立即飙升似乎达到了约50%。
On April 16 2016 an Mw7.8 earthquake with epicentre 29km south-southeast of Muisne in northern Manabi caused around 700 fatalities, injured 30,000 and destroyed several sections of the towns of Pedernales, Portoviejo, Canoa, Bahia de Caraquez and Manta, most of them important centres of tourism on the coast of Ecuador. During May 24-June 7 a team was deployed by the Earthquake Engineering Field Investigation Team (EEFIT) with the objective of surveying the damage and recording observations that would help the scientific and professional community understand the event and its consequences. The team, all co-authors of this paper, investigated structural damage patterns, surveyed 1,332 buildings, validated landslide data obtained from satellite imagery for 30 sites, and interviewed 120 families at 3 shelters. The damage observed in low- and mid-rise buildings seems to correlate well with the spectral response measured in Manta, Portoviejo, and Pedernales. Satellite-based landslide identification proved effective in an 80-90% of the cases investigated. The immediate unemployment spike, based on our limited survey, seemed to reach about 50% in the affected population.
