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

Simple relationship between seismic activity along Philippine Sea slab and geometry of oceanic Moho beneath southwest Japan
TL;DR: In this article, a detailed configuration of the oceanic Moho (slab Moho) within the subducting Philippine Sea slab (PHS) was constructed based on a receiver function (RF) analysis.

Source rupture processes of the 2016 Kumamoto, Japan, earthquakes estimated from strong-motion waveforms
TL;DR: Based on the observations of surface ruptures, the spatial distribution of aftershocks, and the geodetic data, a realistic curved fault model was developed for source-process analysis of the 2016 Kumamoto, Japan, earthquakes.

A crustal thickness map of Africa derived from a global gravity field model using Euler deconvolution
Getachew E. Tedla,Getachew E. Tedla,M. van der Meijde,Andrew A. Nyblade,Andrew A. Nyblade,F.D. van der Meer +5 more
TL;DR: This paper developed a new continental scale crustal model for Africa by modelling the free-air gravity anomaly EIGEN-GL04C, which was developed from 30 months of GRACE Level 1B data covering the period from 2003 February to 2005 July, and surface gravity data from seven different sources.

Along‐strike variations in short‐term slow slip events in the southwest Japan subduction zone
TL;DR: In this paper, the authors used a genetic algorithm and a least square method to inverted the data for tilt steps that were caused by slow slip events and were detected by at least four stations situated near the source of the tremor.

Broadband seismic monitoring of active volcanoes using deterministic and stochastic approaches
Hiroyuki Kumagai,Masaru Nakano,Takuto Maeda,Hugo Yepes,P. Palacios,Mario Ruiz,S. Arrais,M. Vaca,Indira Molina,Tadashi Yamashima +9 more
TL;DR: In this paper, the authors systematically used two approaches to analyze broadband seismic signals for monitoring active volcanoes: one is waveform inversion of very-long-period (VLP) signals assuming possible source mechanisms; the other is a source location method of long period (LP) events and tremor using their amplitudes.

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.
