... Abstract Plate boundary forces acting within the Cocos Plate that is being subducted at a rate of 8.5–9.0 cm a −1 towards N32°E below the Caribbean Plate and the Panama microplate are found responsible for contemporaneous superimposed compressive, wrench and extensive fault patterns in Central...

... and reported with a magnitude ( M w ) of 6.4 and a strike-slip mechanism with a large normal dip-slip motion. This mechanism agrees with mapped faults in the area that suggest transtensional deformation on the forearc and the entire western boundary of the Panama microplate. Aftershock locations do...
