Any investigation of recorded data on this earthquake is very important for testing the operation of the digital monitoring networks and understanding the preparation, occurrence, and adjustment of stress/strain of strong continental earthquakes. In this paper we investigated the coseismic response changes of well water level of groundwater and volume strain meter of bore hole in digital earthquake monitoring network of Capital area and its vicinity, due to the Nov.14, 2001 Ms8.1 Kunlun Mountain earthquake. The responding time, shapes or manners, amplitudes, and lasting time of well water level and strain-meters to seismic wave are studied in comparison. Then we discussed the possibility that the response changes of groundwater to strong distant earthquakes can be understood as one kind of observing evidence of stress/strain changes induced by distant earthquake.展开更多

We assessed per capita household CO2 emissions（PHCEs） based on different household consuming demands（including clothing, food, residence, transportation and service） by using provincial capital city level survey data in China. The results showed that：（1） there was a declining trend moving from eastward to westward as well as moving from northward to southward in the distribution of PHCEs.（2） PHCEs from residence demand were the largest which accounted for 44% of the total.（3） Correlation analysis and spatial analysis（Spatial Lag Model（SLM） and Spatial Error Model（SEM）） were used to evaluate the complex determinants of PHCEs. Per capita income（PI） and household size（HS） were analyzed as the key influencing factors. We concluded that PHCEs would increase by 0.2951% and decrease by 0.5114% for every 1% increase in PI and HS, respectively. According to the results, policy-makers should consider household consuming demand, income disparity and household size on the variations of PHCEs. The urgency was to improve technology and change household consuming lifestyle to reduce PHCEs.展开更多
