Preliminary Co-seismic Landslide Inventory Map for Portoviejo,
Ecuador
0 0.5 10.25km
Interpretation
International Charter Disaster Activation 564, coordinated
byUNOSAT.This inventory was prepared in rapid mapping mode using
acombination of satellite image interpretation and
sourcinginformation from news reports and crowdsourcing.No
liability concerning the content or use thereof is assumed by
theproducer. Product published 25 April 2016 and designed
forviewing at A0 paper size.
Data sources
This satellite image interpretation shows a landslide
inventorymap produced by the British Geological Survey. The scale
ofmapping was between 1:1,000 and 1:10,000 and the satelliteimage
resolution is 0.5 m. Insets show detailed mapping.In the Portoviejo
area 29 sites were identified where river banksare affected by
mainly rotational landslides. These potentiallyaffect the stability
of bridge abutments, houses and other assets.The landslides are
likely caused by a combination of high waterlevels and seismic
shock. The inset (top right) shows a largepotential landslide area,
but this is uncertain. The hillytopography surrounding the city
does not appear to be affectedby co-seismic landslides. This
inventory requires field verification.
