Journal ArticleDOI
A new method for measuring deformation on volcanoes and other natural terrains using InSAR persistent scatterers
TL;DR: In this paper, a new InSAR persistent scatterer (PS) method was proposed for analyzing episodic crustal deformation in non-urban environments, with application to volcanic settings.
Journal ArticleDOI
A multi-temporal InSAR method incorporating both persistent scatterer and small baseline approaches
Andrew Hooper,Andrew Hooper +1 more
TL;DR: A new method is presented that combines both approaches, to extract the deformation signal at more points and with higher overall signal-to-noise ratio than can either approach alone.
Journal ArticleDOI
Persistent scatterer interferometric synthetic aperture radar for crustal deformation analysis, with application to Volcán Alcedo, Galápagos
TL;DR: In this paper, the spatial correlation of interferogram phase was used to find pixels with low-phase variance in all terrains, with or without buildings, for persistent scatterer (PS) analysis.
Journal ArticleDOI
Recent advances in SAR interferometry time series analysis for measuring crustal deformation
TL;DR: In this paper, a review of recent advances in time series SAR interferometry methods that further improve accuracy is presented, including improved algorithms applied to image deformation associated with the 2010 eruption of Eyjafjallajokull volcano, slow slip on the Guerrero subduction zone in Mexico, and tectonic deformation in western Anatolia, Turkey.

TL;DR: Lateral dyke growth with segment barrier breaking by pressure build-up in the dyke distal end explains how focused upwelling of magma under central volcanoes is effectively redistributed over long distances to create new upper crust at divergent plate boundaries.
