“…Five [Atkinson and Boore, 2003, Crouse, 1991, García et al, 2005, Lin and Lee, 2008, McVerry et al, 2006 out of the eight selected models are ranked in the lowest capability class (D) by the method of Scherbaum et al [2004] and only one model, that of Kanno et al [2006], is ranked higher than C. The results for the GMPEs of Atkinson and Boore [2003], Crouse [1991] and Youngs et al [1997] are in agreement with those presented by Douglas et al [2006] based on their smaller dataset.…”

“…It was decided to update the analysis of Douglas et al [2006] for this type of earthquake for a number of reasons: a) the number of available strong-motion records from subduction earthquakes from this region is about double that available when Douglas et al [2006] compiled data from this region; b) many records from a large (M w 7.4) intraslab earthquakes that occurred in 2007 improved the distribution with respect to magnitude and distance; and c) a number of new GMPEs for subduction earthquakes have been published and hence can be compared to the observations. One of the most important findings is that the recent ground-motion models developed from Japanese data [Kanno et al, 2006, Zhao et al, 2006 provide quite good predictions of observed earthquake ground motions and their variabilities in the Lesser Antilles. Other recent GMPEs derived for Mexico [García et al, 2005], Taiwan [Lin and Lee, 2008] and New Zealand [McVerry et al, 2006] are ranked poorly by the method of Scherbaum et al [2004] for this dataset.…”

“…All the selected models underestimate the groundmotion variability observed in the Lesser Antilles (shown by values of STDNR greater than unity) although for the models of Kanno et al [2006] and Youngs et al [1997] this underestimation of the variability is small (in fact, these models predict larger variabilities for intraslab events than observed). As discussed by Douglas et al [2006] the reasons for the apparently poor match between predictions and observations could be partly due to an observational dataset from a different magnitude and distance range than used by the developers of the selected GMPEs.…”

“…Considering the records from intraslab or interface events separately does not significantly affect the results obtained (although Kanno et al [2006] performs better for ground motions from intraslab events than for interface events). Figure 3 shows the normalized residuals for PGA and for spectral acceleration (SA) at 1 s for the equation of Kanno et al [2006] with respect to hypocentral distance and M w for the two types of subduction earthquakes (intraslab and interface).…”

It shows that the model of Kanno et al [2006] generally provides good predictions of PGA and SA at 1 s at all distances from 50 to 300 km and for all magnitudes from 4.8 to 7.4 for both types of events.…”

This brief article presents a quantitative analysis of the ability of eight published empirical ground-motion prediction equations (GMPEs) for subduction earthquakes (interface and intraslab) to estimate observed earthquake ground motions on the islands of the Lesser Antilles (specifically Guadeloupe, Martinique, Trinidad and Dominica). In total, over 300 records from 22 earthquakes from various seismic networks are used within the analysis. It is found that most of the GMPEs tested perform poorly, which is mainly due to a larger variability in the observed ground motions than predicted by the GMPEs, although two recent GMPEs derived using Japanese strong-motion data provide reasonably good predictions. Analyzing separately the interface and intraslab events does not significant modify the results. Therefore, it is concluded that seismic hazard assessments for this region should use a variety of GMPEs in order to capture this large epistemic uncertainty in earthquake ground-motion prediction for the Lesser Antilles.

We determine the first high‐resolution P and S wave attenuation (Q) tomography beneath the entire Japan Islands using a large number of high‐quality t∗ data collected from P and S wave velocity spectra of 4222 local shallow and intermediate‐depth earthquakes. The suboceanic earthquakes used in this study are relocated precisely using sP depth phases. Significant landward dipping high‐Q zones are revealed clearly, which reflect the subducting Pacific slab beneath Hokkaido and Tohoku, and the subducting Philippine Sea (PHS) slab beneath SW Japan. Prominent low‐Q zones are visible in the crust and mantle wedge beneath the active arc volcanoes in Hokkaido, Tohoku, and Kyushu, which reflect source zones of arc magmatism caused by fluids from the slab dehydration and corner flow in the mantle wedge. Our results also show that nonvolcanic low‐frequency earthquakes (LFEs) in SW Japan mainly occur in the transition zone between a narrow low‐Q belt and its adjacent high‐Q zones right above the flat segment of the PHS slab. This feature suggests that the nonvolcanic LFEs are caused by not only fluid‐affected slab interface but also specific conditions such as high pore pressure which is influenced by the overriding plate.

Discovery, Controls, and Hazards of Widespread Deep‐Seated Gravitational Slope Deformation in the Etsumi Mountains, Central Japan

Deep‐seated gravitational slope deformation (DSGSD) is a largely unnoticed but important long‐term mass wasting process that may result in catastrophic failure of mountain slopes. Manifested by small topographic irregularities such as ridge‐parallel scarps and linear depressions, it has been predominantly reported in alpine landscapes above timber lines. On the basis of area‐wide high‐resolution topographic data acquired by light detection and ranging (lidar) surveys, we here show that ~96% of existing gravitational scarps have been hidden under forest canopies in the Etsumi Mountains, central Japan. The scarps are surprisingly widespread over the mountains with a mean line density of as large as 0.87 km/km2. Our analyses of the scarp distribution suggest that uphill‐facing scarps are primary geomorphic signals of DSGSD with a destabilized rock mass larger than ~105 m2, whereas downhill‐facing scarps principally occur in response to more localized slope deformation. In terms of controls, topography is by far the most influential factor in triggering and promoting DSGSD. Despite the M 7.5 earthquake in 1891, impact of large local earthquakes proves to be not very strong. Comparison with preexisting landslide maps further suggests that DSGSD and large‐scale landslides are not different slope processes but represent different stages of the same process. Our results highlight limitations of aerial‐photograph interpretation in forest‐covered mountains and the need for lidar‐assisted mapping for deeper understanding of this long‐term process and interactions between surface and tectonic processes.
