Fore-arc motion and Cocos Ridge collision in Central America
[1] We present the first regional surface velocity field for Central America, showing crustal response to interaction of the Cocos and Caribbean plates. Elastic half-space models for interseismic strain accumulation on the dipping subduction plate boundary fit the GPS data well and show strain accumulation offshore and beneath the Nicoya and Osa peninsulas in Costa Rica but not in Nicaragua. Si...
متن کاملDepositional sequences and sequence boundaries in fore-arc coastal embayments: case histories from Central America
From Oligocene to Recent times a series of tectomcally controlled coastal embayments fonned on the Pacific fore-arc side of the southern Central American island-arc system. Each of these basins shows characteristic stratal geometries and facies distributIOns reflecting the complex interaction of changes of sea level. volcaniclastic input. and tectonic activity (subsidence, uplift). Sequential s...
متن کاملLarge-scale slope failure and active erosion occurring in the southwest Ryukyu fore-arc area
The southwestern Ryukyu area east of Taiwan Island is an arcuate boundary between Philippine Sea Plate and Eurasian Plate. The topographic features in the area are characterised by (1) a large-scale amphitheatre off Ishigaki Island, just on the estimated epicentre of the tsunamigenic earthquake in 1771, (2) lots of deep sea canyons located north of the amphitheatre, (3) 15–20 km wide fore-arc b...
متن کاملSlip Distribution of the 2014 Mw=8.1 Pisagua, Northern Chile, Earthquake Sequence Estimated From Coseismic Fore-Arc Surface Cracks
The 2014 Mw= 8.1 Iquique (Pisagua), Chile, earthquake sequence ruptured a segment of the Nazca-South America subduction zone that last hosted a great earthquake in 1877. The sequence opened >3700 surface cracks in the fore arc of decameter-scale length and millimeter-to centimeter-scale aperture. We use the strikes of measured cracks, inferred to be perpendicular to coseismically applied tensio...
متن کاملBringing nature to the fore.
This article has two aims: first, to give an historic overview of the nature-nurture debate in relation to how mothers learn to breastfeed. The overview will relate how the 'nurture' perspective came to dominate our understanding of the ontogeny of breastfeeding. The second aim is to propose professional breastfeeding competencies in an attempt to integrate the 'nature' perspective within early...
