The seismic event sent tens of thousands to refugee camps and affected some two million persons directly, mostly in the coastal area south of the epicenter. Due to large population movement to the Ecuadorian costs in the last decades, high economical losses occurred due to structural damage to almost 30,000 properties, including family houses, but also due to interruption and damage to infrastructure that served main sources of income from fishing, tourism and other industries. Within three days of the main event, field data were collected and a geological survey was performed and provided input for the evaluation of the maximum macroseismic intensities and the predominant geomorphological features. Data on 290 sampling stations on earthquake-induced (coseismic) ground effects were documented and used to reconstruct a geological isoseismal map. Combining the compiled and recorded coseismic field data of higher macroseismic intensities, we developed an intensity map applying the methodology and definitions of the ESI 2007 scale. We also evaluated the distribution and intensities of the aftershocks that demonstrated spatial-temporal affinities. Geotechnical observations of embankment and port behavior following potential development of soil liquefaction and associated loss of strength are discussed based on the GEER-ATC reconnaissance mission in Ecuador [1]. Documentation on the tsunami that followed the main event [2], although less intense and less destructive from historic and expected tsunamis in the region is presented. Closing thoughts on the needs for rebuild towards resilience for future earthquakes and other natural hazards are briefly discussed.
