Abstract:
SUMMARY The Ecuadorian convergent margin has experienced many large mega-thrust earthquakes in the past century, beginning with a 1906 event that propagated along as much as 500 km of the plate interface. Many subsections of the 1906 rupture area have subsequently produced Mw ≥ 7.7 events, culminating in the 16 April 2016, Mw 7.8 Pedernales earthquake. Interestingly, no large historic events Mw ≥ 7.7 appear to have propagated southward of ∼1°S, which coincides with the subduction of the Carnegie Ridge. We combine data from temporary seismic stations deployed following the Pedernales earthquake

Abstract:
Abstract The stratigraphic revision of the southern coastal Ecuadorian series makes possible the reconstruction of the pre-collision history of the Caribbean plateau accreted to the Ecuadorian margin. The Coniacian age of the oceanic basement (Piñón Fm) indicates that the latter is part of the Caribbean oceanic plateau. It is overlain by the Calentura Fm, which comprises from base to top: (i) 20 to 200 m of lavas and volcanic breccias of arc affinity (Las Orquídeas Mb), (ii) siliceous, organic rich black limestones of (middle?) Coniacian age, (iii) red, radiolarian rich, calcareous cherts a

Abstract:
A new species of Octomeria was found during an orchid research expedition in the southern Ecuadorian Amazon. Octomeria jimenezii is described and illustrated, and information on its distribution, habitat and conservation status is provided. The newly proposed taxon is morphologically similar to O. pacii, from which it differs by the lower lateral lobes, with an obtuse to subacute angle to the anterior margin.

Abstract:
A new species, <i>Chactas moreti </i>sp. n., is described from Ecuadorian Amazonia. It can be distinguished from <i>Chactas mahnerti</i> Lourenço, 1995, the other known species of this genus from Ecuador by its smaller body size, distinct morphometric values, overall darker blackish-brown coloration, totally smooth vesicle, and a concave anterior margin of carapace. This is the second confirmed record of the genus <i>Chactas </i>Gervais from Ecuador. The geographical pattern of distribution of the genus is also discussed.

Abstract:
GNSS observations constitute the main tool to reveal Earth’s crustal deformations in order to improve the identification of geological hazards. The Ecuadorian Andes were formed by Nazca Plate subduction below the Pacific margin of the South American Plate. Active tectonic-related deformation continues to present, and it is constrained by 135 GPS stations of the RENAGE and REGME deployed by the IGM in Ecuador (1995.4–2011.0). They show a regional ENE displacement, increasing towards the N, of the deformed North Andean Sliver in respect to the South American Plate and Inca Sliver relatively stab

Abstract:
SUMMARY The Ecuadorian forearc is a complex region of accreted terranes with a history of large megathrust earthquakes. Most recently, a Mw 7.8 megathrust earthquake ruptured the plate boundary offshore of Pedernales, Ecuador on 16 April 2016. Following this event, an international collaboration arranged by the Instituto Geofisico at the Escuela Politécnica Nacional mobilized a rapid deployment of 65 seismic instruments along the Ecuadorian forearc. We combine this new seismic data set with 14 permanent stations from the Ecuadorian national network to better understand how variations in crusta

Abstract:
Chapter 3 explains how the gap between state-centric views on borderlines and transnational realities at the margins turn borderlands in vulnerable regions into extreme cases of complex security dynamics. First, it presents how state-centric views that stop at the borderline have historically shaped security policies toward the Colombia-Ecuador and Colombia-Venezuela borders. It then contrasts these with a transnational perspective that analyzes security dynamics from within the Colombian-Ecuadorian and Colombian-Venezuelan borderlands. Adopting such a transnational borderland lens, the chapte

Abstract:
Despite numerous efforts and a large investment by the Ecuadorian Government and the international community, fishery management in Galapagos remains highly conflictive and essentially ineffective. Levels of mistrust and lack of communication have eroded the governance mechanisms in place to resolve conflicts over competing uses in the Reserve. In an effort to provide new information and analytical content into the policy debate regarding fisheries management in the marine reserve, the authors of this paper developed this research utilizing an economic approach to regulating use of the primary

This paper evaluates how new information influences families applica- tions and assignment outcomes in elementary school choice settings. Specifi- cally, using a multi-country RCT based in Tacna, Peru and Manta, Ecuador, we examine the effect of providing personalized information on schooling alternatives and placement risk. We find that applicants who received feed- back on placement risk and a suggestion of new schools add more schools to their applications and were more likely to include recommended schools than other alternatives available.
