TLDR
GMT allows users to manipulate (x,y,z) data, and generate PostScript illustrations, including simple x-y diagrams, contour maps, color images, and artificially illuminated, perspective, and/or shaded-relief plots using a variety of map projections.Abstract:
Version 31 of the Generic Mapping Tools (GMT) has been released More than 6000 scientists worldwide are currently using this free, public domain collection of UNIX tools that contains programs serving a variety of research functions GMT allows users to manipulate (x,y) and (x,y,z) data, and generate PostScript illustrations, including simple x-y diagrams, contour maps, color images, and artificially illuminated, perspective, and/or shaded-relief plots using a variety of map projections (see Wessel and Smith [1991] and Wessel and Smith [1995], for details) GMT has been installed under UNIX on most types of workstations and both IBM-compatible and Macintosh personal computersread more

Migration of widespread long-lived volcanism across the Galápagos Volcanic Province: Evidence for a broad hotspot melting anomaly?
TL;DR: In this paper, the authors conducted a first reconnaissance dredge/grab sampling of submerged regions of the Galapagos Volcanic Province (GVP) and found that 40Ar/39Ar ages for many of these new basement samples and evaluate their implications for various models put forward to explain the origin of the GVP.

Control of pore fluid pressure diffusion on fault failure mode: Insights from the 2009 L'Aquila seismic sequence
TL;DR: In this paper, the authors model the time evolution of pore fluid pressure northward from the main hypocenter and show that during the sequence, the Campotosto fault failed in multiple episodes, when specific patches/asperities underwent fluid pressure-related strength reductions of 7-10 MPa.

InSAR analysis of surface deformation over permafrost to estimate active layer thickness based on one-dimensional heat transfer model of soils.
TL;DR: A novel method to estimate active layer thickness (ALT) over permafrost based on InSAR (Interferometric Synthetic Aperture Radar) observation and the one-dimensional heat transfer model of soils, which can potentially be used for deriving high-resolution ALTs in other remote areas similar to QTP.

Broad-band Lg attenuation modelling in the Middle East
TL;DR: In this paper, a broad-band tomographic model of Lg attenuation in the Middle East derived from source and site-corrected amplitudes is presented for a wide range of frequencies ranging from 0.5 to 10 Hz.

Mantle transition zone structure beneath the Changbai volcano: Insight into deep slab dehydration and hot upwelling near the 410 km discontinuity
TL;DR: In this article, the authors studied the detailed mantle transition zone structure under the active Changbai intraplate volcano in Northeast China by using a receiver function method and revealed significant depth variations of the 410, 520, and 660 km discontinuities.

Free software helps map and display data
Paul Wessel,Walter H. F. Smith +1 more
TL;DR: The Generic Mapping Tools (GMT) is introduced, which is a free, public domain software package that can be used to manipulate columns of tabular data, time series, and gridded data sets and to display these data in a variety of forms ranging from simple x-y plots to maps and color, perspective, and shaded-relief illustrations.
