Abstract Sangay volcano (Ecuador) shows a quasi-continuous activity at least since the seventeenth century and has produced several eruptions which affected towns cities considerable distance (up to > 170 km). For this reason, despite its remote location, recent efforts were aimed reviewing volcanic history, quantifying occurrence probability of four eruptive scenarios different magnitude (Strong Ash Venting, Violent Strombolian, sub-Plinian, Plinian) associated uncertainty, and, for each...
Abstract A new view of Ecuador's complex geodynamics has been developed in the course modeling seismic source zones for probabilistic hazard analysis. This study focuses on two aspects plates' interaction at a continental scale: (a) age‐related differences rheology between Farallon and Nazca plates—marked by Grijalva rifted margin its inland projection—as they subduct underneath central Ecuador, (b) rapidly changing convergence obliquity resulting from convex shape South American...
Building a unified and homogeneous earthquake catalog is preliminary step for estimating probabilistic seismic hazard in country. Ecuador, territory of ∼600 km×500 km, characterized by an active seismicity, both the shallow crust subduction zone. Several international local catalogs are available, covering different time spatial windows, magnitude types uncertainties. After careful analysis each catalog, particular completeness uncertainty levels, we propose priority scheme merging...

Ecuador has 55 active volcanoes in the northern half of Ecuadorian Andes. There, consequences volcanism include ashfalls, pyroclastic flows (fast moving fluidized material hot gas, ash, and rock), lahars (mudflows), which result serious damage locally regionally thus are major concern to Ecuadorians. In particular, Tungurahua (elevation, 5023 meters) Cotopaxi 5876 high‐risk volcanoes. Since 1999, eruption activity at continued produced ashfalls that towns villages on flanks volcano. More...
The devastating April 16, 2016, Pedernales, Ecuador, Mw 7.8 earthquake was among a sequence of ruptures that occurred along the seismically segmented North Andean subduction zone. It caused 700 fatalities, and more than 7,000 people were injured. magnitude location it similar to those May 14, 1942, earthquake, relaxing some strain accumulation had built up over 74 years. A weak tsunami detected in four nearby tide gauges. Analysis records provides useful information on tsunami. An estimate...
<title>Abstract</title> We present a tephra fallout hazard assessment of Sangay volcano, Ecuador. This volcano is under semi-permanent activity at least since the 17th century, and has produced several eruptions whose products have affected towns cities considerable distance (up to > 170 km). For this reason, despite its remote location, recent efforts been aimed reviewing volcanic history; quantifying occurrence probability various eruptive scenarios associated uncertainty; and, for each...
