| 1 | Assessment of geodetic strain and stress variations in Nepal due to 25 April 2015 Gorkha earthquake:Insights from the GNSS data analysis and b-value显示文摘A magnitude M;7.8 earthquake occurred on 25 April 2015(referred as Gorkha earthquake).We have analyzed the spatial variation of b-value and two-dimensional strain within Nepal Himalaya before and after the Gorkha earthquake.We have used continuous Global Navigation Satellite System(GNSS)data from 30 stations in the Nepal region for geodetic strain estimation and earthquake data for b-value estimation.The GNSS data were processed using double differencing technique for the accurate position of each station.The precise velocity vectors show a general azimuth of north east for all the stations and have been used to derive two-dimensional strain.Between epicenters of Gorkha(25 April 2015)and Dolakha earthquakes(12 May 2015),we observed high co-seismic horizontal displacements(0.2 m to 2 m).In the Pre-seismic deformation study,maximum strain accumulation(56.40×10;)and low bvalue(0.79-0.89)was observed in and around the Western Nepal region,which may be responsible for the 2015 Gorkha earthquake.The potential seismic zones were identified by GIS based integration of geodetic strain and b-value map and superimposition using weighted overlay method.The Maximum strain and low b-value are now observed in the eastern part of Nepal.Hence,the spatial disposition of elastic energy has changed after the two major earthquakes and continuous seismic hazard assessment is required in the eastern Nepal. | Sravanthi Gunti Priyom Roy J.Narendran Ramesh Pudi S.Muralikrishnan K.Vinod Kumar M.Subrahmanyam Y.Israel B.Satish Kumar | 2022 | Geodesy and Geodynamics2022，13，3： | 1 |

| 5 | 印度喀拉拉邦伊都基水库附近小震的精确定位和震源机制:地震成因的启示显示文摘应用印度南部新建的一个拥有21个台站的临时台阵的地震波形,显著提高了喀拉拉邦伊都基水库附近地区小震的检测阀值和参数。我们给出了这一地区16个地震的精确定位,地方震级为1.5~3.6,震源深度7.2~9.9kin。所选6个最好地震的断层面解显示走滑断层错动兼右旋运动。水库加载通常会导致应力的产生和在浅层深度(〈5km)弓l发地震,但是在伊都基水库区域内却没有该深度的地震。记录到的地震仅限于靠近Karur-Kambam-Painavu-Trichur(KKPT)剪切带西北-东南走向的断层。这些结果表明,伊都基水库区域内的地震均属于天然构造地震,而与水库没有联系。 | utpal saikia s.s.rai m.subrahmanyam satyajit dutta somasish bose kajaljyoti borah rishikesh meena 任家琪(译) 李艳娥(校) | 2016 | 世界地震译丛2016，47，3： | 0 |
