| 1 | Fault plane parameters of Sanhe-Pinggu M8 earthquake in 1679 determined using present-day small earthquakes显示文摘The great Sanhe-Pinggu M8 earthquake occurred in 1679 was the largest surface rupture event recorded in history in the northern part of North China plain. This study determines the fault geometry of this earthquake by inverting seismological data of present-day moderate-small earthquakes in the focal area. We relocated those earthquakes with the double-difference method.Based on the assumption that clustered small earthquakes often occur in the vicinity of fault plane of large earthquake, and referring to the morphology of the long axis of the isoseismal line obtained by the predecessors, we selected a strip-shaped zone from the relocated earthquake catalog in the period from 1980 to 2009 to invert fault plane parameters of this earthquake. The inversion results are as follows: the strike is 38.23°, the dip angle is 82.54°,the slip angle is-156.08°, the fault length is about 80 km,the lower-boundary depth is about 23 km and the buried depth of upper boundary is about 3 km. This shows that the seismogenic fault is a NNE-trending normal dip-slip fault,southeast wall downward and northwest wall uplift, with the right-lateral strike-slip component. Moreover, the surface rupture zone, intensity distribution of the earthquake and seismic-wave velocity profile in the focal area all verified our study result. | Xiaoshan Wang Xiangdong Feng Xiwei Xu Guiling Diao Yongge Wan Libin Wang Guangqing Ma | 2014 | Earthquake Science2014，27，6： | 9 |
| 2 | A Stackelberg game approach for demand response management of multi-microgrids with overlapping sales areas显示文摘Microgrids are increasingly participating directly in the electricity market as sellers in order to fulfill the power demand in specific regions.In this study,we consider a demand response management model for multi-microgrids and multi-users,with overlapping sales areas.We construct a Stackelberg game model of microgrids and users,and then analyze the equilibrium strategies systematically.As such,we prove that there is a unique Stackelberg equilibrium solution for the game.In equilibrium,the electricity price strategies of the microgrids and the demand strategies of the users achieve a balance.Furthermore,we propose a numerical algorithm,supported by a simulation,to compute the equilibrium solution and give the proof of convergence. | Jun LI Guangqing MA Tao LI Wushun CHEN Yu GU | 2019 | Science China(Information Sciences)2019，62，11： | 3 |
