The extremely oblique Indo‐Burma subduction zone exhibits dextral strike‐slip faulting along the Sagaing, Kabaw, and Churachandpur‐Mao Faults as well as east‐west shortening between the Sagaing Fault and Bengal Basin. Through regional stress analysis, considering areas from central Tibet, around the eastern Himalaya Syntaxis, to Burma, it has been determined that the principal compressive stress directions align with the principal strain rates. The northeast‐southwest oriented compressive stress direction from the western Shan Plateau continues into Burma. Notably, P axes align with the topographic gradients, and T axes are sub‐parallel to the topographic contours in the Shan Plateau region south of 27°N. These stress patterns are consistent with a gravitational potential energy induced crustal and mantle flow. The alignment of the fast shear wave with the maximum strain rate and the colinear NW‐SE to E‐W fast direction of the SKS wave and T axis determined from focal mechanisms in the Shan Plateau suggest that the mantle lithosphere deforms in concert with the crust. We suggest crust and mantle flow south of the Red River Fault has resulted in widening of the lithosphere in the Shan Plateau in an east‐west direction. Therefore, the Sagaing Fault has bowed approximately 50–100 km westward if we assume that the Sagaing Fault was originally straight. Our results of regional stress inversion are consistent with late Miocene to present E‐W shortening in the Indo‐Burma subduction zone resulting from the release of gravitational potential energy from the central Tibetan Plateau. Plain Language Summary: The movements of the Earth's crust in the Indo‐Burma region are partially caused by India sliding underneath southeast Asia at an angle. The Sagaing Fault, along with other strike‐slip faults in the Indo‐Burma area, accommodates the motion of India and Asia. Even though India and Asia pushing together mostly causes east‐west compression in Burma and the far east of Bangladesh, only about half of the displacement comes from their collision. It's unclear what causes the remaining east‐west displacement. We suggest that the additional compression in Bangladesh and Burma happens because of the collapse of the Tibet Plateau and the flow of the Earth's lithosphere out of central Tibet. Key Points: The E‐W shortening of the Burma Plate is an effect of the release of gravitational potential energy from the central Tibetan PlateauGeometry and kinematics of the sinistral faulting in the Shan Plateau are consequences of radially directed compression from fan‐shaped lithospheric flowLithospheric flow around the southeast margin of the Tibetan Plateau has affected stress in northern southeast Asia and Burma [ABSTRACT FROM AUTHOR]

Seismic attenuation across the US is estimated using station ML magnitude data from the USArray. Station magnitudes are recalibrated back to amplitude and back projected in a 2-D tomography. Data represent the amplitudes of the horizontal components of the Lg phase. The western US shows regions of very high attenuation and contrasts with the lesser attenuation of the eastern US. Individual attenuation anomalies can be clearly tied to regional geology. Station gains show broad regional variations that match geographic regions. Most of the high-attenuation areas are regions of high geothermal activity suggesting that intrinsic attenuation dominates over scattering attenuation. An exception is the central San Andreas Fault zone because it lacks any localized heat-flow anomaly. The US east of the Rocky Mountains is bland and contains none of the high-attenuation regions of the western US. Instead, the central US has low-attenuation patches that do not obviously correspond to geologic province. Sediments of the Gulf Coast Plain, Willison Basin and Michigan Basin do show up as intermediate attenuation while the Illinois Basin, Appalachian Basin and other basins are not apparent. In Alaska, attenuation is generally less than the western US, but still much greater than the eastern US. In southeast Alaska, the Wrangell Volcanic Field causes a sizeable high-attenuation zone. The volcanic Aleutian Mountains also have high attenuation. However, moderate to high attenuation also correlates with the tertiary sedimentary basins in Alaska. The North Slope Basin does not seem to attenuate. Thicker crust and mountain roots tend to show less attenuation, if anything, but this correspondence is most likely due to differences in temperature and seismic velocity. Heat, scattering and young sedimentary basins create seismic attenuation in the continental crust. [ABSTRACT FROM AUTHOR]

Using Pn -wave traveltimes from three regional distance ranges we generated Pn tomography models to investigate the 3-D nature of the uppermost mantle lid P -wave velocity structure beneath the Tibetan Plateau and surrounding regions. Significant velocity variations spatially and with depth are observed. High-velocity regions are found beneath the Himalayas and most parts of southern Tibet. These high-velocity regions can be interpreted as subducting Indian continental mantle lithosphere, accreted terranes and a cold, non-convective mantle wedge beneath central Plateau. They are disjointed suggesting that the subducting Indian lithosphere is fragmented laterally. In the western Tibetan Plateau, the high-velocity region extends northwards to the middle of Qiangtang Terrane. In the central Plateau, the high-velocity region reaches near the Bangong–Nujiang suture. The northern extent of the subducted Indian continent cannot be determined uniquely from Pn models because the Indian plate dips moderately beneath southeastern Tibet. Around the Plateau, Tarim, Qaidam, Gonghe and Sichuan basins are floored by high-velocity Asian continental blocks that keep the elevation of these basins lower than surrounding regions. We found no evidence of an ongoing southward subduction of Asian lithosphere beneath central to northeastern Tibetan Plateau. Two major Pn low-velocity anomalies are found beneath northern and northeastern Tibet, primarily within the Qiangtang and Songpan-Ganzi Terranes. The northern Tibet low-velocity mantle is situated in a continental backarc of the India–Asia continental subduction zone, and hence we interpreted this region as thin thermal lithosphere with upwelling mantle driving by the subducting Indian lithosphere. The Qilianshan is also underlain by a low-velocity mantle structure and could be related to the same upwelling in this continental backarc. A narrow N–S trending low-velocity anomaly is found beneath the Yadong–Gulu Rift and confirmed that the Lhasa Terrane is not limited to the crust, but involves the entire lithosphere. Another pronounced low Pn velocity region is observed in the southeastern Tibetan Plateau, southern Yunnan and northeastern Myanmar. This feature is probably related to backarc convection associated with the subduction and rollback of Indian oceanic slab beneath Myanmar and Yunnan province, China.International Seismological Centre, On-line Bulletin, http://www.isc.ac.uk, Internatl.

The 127 station NorthEast China Extended SeiSmic Array (NECESSArray) provides large quantities of high quality seismic data in northeast China that allow us to resolve lateral variations of Lg Q or crustal attenuation at 1 Hz (Qo)to2.0° or greater. Using the reverse two-station/event method with 11 642 Lg path-amplitudes from 78 crustal earthquakes, we obtain a 2-D tomographic image of Lg Qo with values ranging from -50 to 1400. A high degree of detail in the lateral variation of Lg attenuation is revealed in our tomographic image. High Qo regions are found in the Great Xing'an, Lesser Xing'an and Songen-Zhangguangcai Ranges. Low Qo regions are observed in the Songliao, Sanjiang and Erlian Basins. The lowest Qo is found near the Wudalianchi volcanic field and other Quaternary volcanic fields, the southern Songliao Basin, the western edge of the Erlian Basin and the Sanjiang Basin. Low Qo values are measured for paths that cross sedimentary basins with thick, unconsolidated sediments. Most of the high Lg attenuation in the Songliao Basin correlates reasonably well with low crustal Rayleigh wave phase velocity anomalies. The highest attenuating regions also correlate well with regions of Holocene volcanism. [ABSTRACT FROM AUTHOR]

We have selected 10,899 ML amplitude readings from 1732 events recorded by 91 stations, as reported in the Annual Bulletin of Chinese Earthquakes (ABCE), and have used tomographic imaging to estimate the lateral variations of the quality factor Q0 (Q at 1 Hz) within the crust of Northern China. Estimated Q0 values vary from 115 to 715 with an average of 415. Q0 values are consistent with tectonic and topographic structure in Eastern China. Q0 is low in the active tectonic regions having many faults, such as the Shanxi and Yinchuan Grabens, Bohai Bay, and Tanlu Fault Zone, and is high in the stable Ordos Craton, Q0 values are low in several topographically low-lying areas, such as the North China, Taikang-Hefei, Jianghan, Subei-Yellow Sea, and Songliao basins, whereas it is high in mountainous and uplift regions exhibiting surface expressions of crystalline basement rocks: the Yinshan, Yanshan, Taihang, Qinlin, Dabie and Wuyi Mountains, and Luxi and Jiaoliao Uplifts. Quality-factor estimates are also consistent with Pn- and Sn-velocity patterns. High-velocity values, in general, correspond with high Q0 and low-velocity values with low Q0. This is consistent with a common temperature influence in the crust and uppermost mantle. [ABSTRACT FROM AUTHOR]

Purpose: To report a case of endogenous endophthalmitis as the presenting sign of a disseminated Scedosporium prolificans infection., Methods: A 38-year-old woman on chronic immunosuppressive treatment for a cardiac transplant was examined for blurry vision in her right eye. Dilated fundus examination in the right eye revealed a large serous retinal detachment with subretinal cream-colored masses., Results: Complete pars plana vitrectomy with vitreal biopsies was performed and revealed S. prolificans on culture. Multiple intravitreal voriconazole injections as well as systemic voriconazole and terbinafine resulted in control and suppression of both the ocular and systemic disease., Conclusion: Scedosporium prolificans endogenous endophthalmitis represents a difficult to treat opportunistic infection in immunocompromised patients. However, newer-generation antifungals offer the potential for suppression of systemic disease and the possibility of avoiding enucleation in the setting of endophthalmitis.
