Earthquake Ecuador

(16 April 2016)

Overview

On Saturday, April 16, 23:58 UTC (18:58 local time), a 7.8-magnitude earthquake struck offshore of the west coast of northern Ecuador, near the coastal town of Muisne, the worst since the 1949 Ambato Earthquake. The epicentre of the quake was along the Pacific coast in a sparsely populated region, approximately 170 km from the country’s capital city, Quito. More than 400 minor to major aftershocks have been recorded since Saturday (16 April 2016). The Government has declared a state of emergency in six coastal provinces (Guayas, Manabi, Santo Domingo, Los Rios, Esmeraldas and Galapagos). Hundreds of infrastructures, including hospitals and schools, and several residential and commercial areas have been damaged. According to the latest information available* through Ecuador’s Risk Management Office, there have been at least 587 deaths, 153 missing, 8,340 recorded injures, and 25,376 individuals who have sought shelter. (*statistics as available at the time of writing of this report)

UNOSAT Building Damage Assessment

UNITAR-UNOSAT on behalf of UN OCHA activated the International Charter on Space and Major Disasters on 17 April 2016 to assist with satellite based damage assessment covering Earthquake affected areas. Priority Areas of Interest (AOIs) for post-earthquake satellite imagery acquisition have been requested by UNOCHA based on Earthquake intensity areas provided by USGS as well as population exposure to M7.8 shaking zones. Within the first 12 hours of the Earthquake, on 17 April 2016, UNITAR-UNOSAT produced a preliminary population exposure. UNITAR-UNOSAT is also supporting UNOCHA, and UNDAC team deployed to earthquake affected areas with the overall coordination of satellite analysis done by UNIATAR/UNOSAT and European Commission’s Copernicus Emergency Management Service through GDACS’ Satellite Mapping and Coordination System (SMCS). Preliminary damage assessment was conducted by comparing the post disaster satellite images with available pre disaster images. All the completed, current and future mapping activities done by UNITAR-UNOSAT as well as other satellite mapping groups can be viewed through GDACS/SMCS. This report provides a summary of satellite based analysis undertaken by UNITAR-UNOSAT and European Commission’s Copernicus Emergency Management Service from 18 April to 22 April, according to availability of suitable post disaster satellite imagery. The extent of damage is categorized into three main levels – Destroyed, Severe Damage and Moderate Damage. Please note that the four damage level classes from Copernicus have been aggregated into three, to summarize the results. All the maps and products from UNOSAT are available at: http://www.unitar.org/unosat/maps/ECU and from Copernicus are available at: http://emergency.copernicus.eu/mapping/list-of-components/EMSR159. Combined satellite damaged assessment done by UNITAR-UNOSAT and Copernicus are also available through a LIVE WEB MAP.

Population Exposure

UNITAR–UNOSAT also made an estimate of potential population living within the light to strong shake zones using the intensity data from USGS and population data from WorldPOP 2010 as of 17 April 2016.
