Origin and emplacement of Mariana forearc seamounts
Geology, 1985Large seamounts occur on the outer half of the Mariana forearc. They represent a new class of seamounts consisting of horsts and diapirs of metamorphosed forearc material. The degree of metamorphism in this material depends on the amount of water available and the pressure-temperature regime of the forearc wedge. The major source for the water involved

Extension in the northern Mariana inner forearc
Journal of Geophysical Research: Solid Earth, 1994Seismic reflection, SeaMARC II acoustic imagery, and bathymetric data across the northern Mariana island arc reveal dense, high‐angle, normal faulting of the arc and inner forearc. Faults, with throws up to 780 m, cut a thick sequence of stratified but otherwise undeformed sediments.

Development of forearcs of intraoceanic subduction zones
Tectonics, 1983The uplifted Costa Rican forearc landward of the Middle America Trench and the Mariana forearc drilled on IPOD leg 60 both lack the thick clastic sequences, complex deformation, and abundant evidence of accretion which characterize more widely known forearcs that border continents.

Active Deformation in the Northern Ecuadorian Forearc
The processes that influence landscape evolution can be observed through instantaneous events such as earthquakes and over longer timescales in the response of rivers and changes in topography. The Northern Ecuadorian forearc is an active seismic area that has experienced several large magnitude earthquakes, the latest being the 7.8 Mw Pedernales ...Michael Andramuno +6 more
