A new method to identify earthquake swarms applied to seismicity near the San Jacinto Fault, California
S U M M A R Y Understanding earthquake clustering in space and time is important but also challenging because of complexities in earthquake patterns and the large and diverse nature of earthquake catalogues. Swarms are of particular interest because they likely result from physical changes in the crust, such as slow slip or fluid flow. Both swarms and clusters resulting from aftershock sequence...
متن کاملTiming of granulite-facies metamorphism in the eastern Himalayan syntaxis and its tectonic implications
We present geochronological evidence in the eastern Himalayan syntaxis (Namche Barwa) for high-pressure (HP) granulite-facies metamorphism and explain its importance for understanding both the deep continental subduction of the Indian plate beneath Asia and its subsequent exhumation. The timing of peak and retrograde metamorphism in part constrains these processes but is debated. We present zir...
متن کاملClockwise Rotation of Upper-Mantle Strain and Crust-Mantle Coupling Beneath the Eastern Syntaxis Tibet
AB: We performed shear-wave splitting of core phases using a subset of 33 selected events within an array composed of 48 broadband stations that spans a 650x350 km area crossing the Lhasa and the southern part of the Qiangtang terranes. Our results reveal the presence of azimuthal anisotropy with small-to-moderate delay times (0.5-1.4s). The consistency of the splitting parameters with respect ...
متن کاملVariability of repeating earthquake behavior along the Longitudinal Valley fault zone of eastern Taiwan
[1] Two major clusters of repeating earthquake sequences (RES) are found on two fault patches near the Longitudinal Valley fault (LVF) in eastern Taiwan, the Chihshang segment to the south and the Hualien segment to the north. The 25 M 2.3–4.6 RES on the Hualien segment are widely distributed in a NNE direction over a distance of 45 km, whereas on the Chihshang segment, the 30 M 2.2–3.4 RES hav...
متن کاملFluid evolution and thermal structure in the rapidly exhuming gneiss complex of Namche Barwa–Gyala Peri, eastern Himalayan syntaxis
High-grade gneisses (amphibolite–granulite facies) of the Namche Barwa and Gyala Peri massifs, in the eastern Himalayan syntaxis, have been unroofed from metamorphic depths in the late Tertiary–Recent. Rapid exhumation (2–5 mm year) has resulted in a pronounced shallow conductive thermal anomaly beneath the massifs and the intervening Tsangpo gorge. The position of the 300 !C isotherm has been ...
