ggge20091-sup-0001-FigureS1.pdfPDF document1239KFrequency comparison between local earthquakes (LE), low-frequency earthquakes (LFE), nonvolcanic tremor (NVT), and background noise.
ggge20091-sup-0002-FigureS2.pdfPDF document855KParticle motion diagram of the (a) NVT signal, (b) P wave of LFE, and (c) S wave of LFE. BHZ, vertical component; BHN, horizontal N-S component; BHE, horizontal E-W component. The amplitude of NVT and S waves in LFE is higher in the horizontal plane than in the vertical plane. P waves in LFE are higher in the vertical plane.
ggge20091-sup-0003-FigureS3.pdfPDF document339KDelay time between P and S waves for a LFE detected at four stations. Red dots are S-P time for stations located at 10, 34, 39, and 72 km from the epicenter.
ggge20091-sup-0004-FigureS4.pdfPDF document3748KCoherent tremor bursts were (a) visually identified and (b) located using the source-scanning algorithm (SSA). The local brightness maxima (color bar) was determined by systematically searching through all nodes and travel times in the grid.
ggge20091-sup-0005-FigureS5.pdfPDF document519KVertical sections of NVT hypocenters. Red dots are locations of NVT with depth; yellow dots are locations of LFE. (a) N-S section centered at 74.4°W. (b) E-W section centered at 46.1°S. (c) Number of NVTs located with the SSA as a function of depth.
ggge20091-sup-0006-FigureS6.pdfPDF document5292KSpectrogram of ISM station, showing harmonic behavior of tremor occurrence during 2 years (2005–2006) at 1 h sample interval. The figure shows the highest energy at semidiurnal, diurnal, and long-term periods.
ggge20091-sup-0007-FigureS7.pdfPDF document32466KExample of six tremor events that occurred between 8 and 10 October 2005. Tremors occurred during periods of high tidal shear stress acting on a strike-slip fault oriented N80°E, subparallel to Taitao and Darwin transform faults (Figure 9).
ggge20091-sup-0008-Table1.pdfPDF document260KTidal constituents in cycles per hour (cph) of the solid Earth tide produced by the gravitational effects of the Moon and the Sun.
ggge20091-sup-0009-Equations_S1.pdfPDF document58KEquations used to compute vertical and horizontal stresses produced by a load strip of infinite length, constant width 2b, and load per unit area p at any point Q [Murthy, 2002].
