本文采用关联维的计算方法,对四川西部道孚6.9级地震和青海共和6.9级地震过程中的垂直地形变序列分维数进行了计算,得到了如下初步结论和认识:(1)上述两震区远场地形变序列分维数为0.63~0.73,而近场(震中区)序列分维数为0.12~0.49,近场出现明显的降维现象;(2)孕震期间地形变观测序列分维数为0.32~0.46,而震后时期则为0.72~0.85,孕震过程中地形变序列存在明显的降维现象。  相似文献

对云南地区43个GNSS连续站2012-01~2018-12站点位移时间序列进行深加工处理,以期间发生的7次M≥5.7地震为样本,分别获取震前面应变和最大剪应变分布,并对震前应变场分布特征进行研究。结果表明:1) 7次M≥5.7地震前,云南地区存在显著的面应变变化趋势,多数情况下存在强挤压和强拉张并存的格局,累积面应变一般超过±4.0×10-8,地震多发生在面应变(特别是面挤压)变化的高梯度带上;2) 7次M≥5.7地震前,云南地区存在显著的最大剪应变变化趋势,累积最大剪应变一般超过5.0×10-8,地震多发生在最大剪应变变化的高梯度带上;3) 面应变(特别是面挤压)和最大剪应变变化的高梯度带可作为研判未来M≥5.7地震发震地点的重要区域。  相似文献

Based on the time series data from the Aral hydrological station for the period of 1958-2005, the paper reveals the long-term trend and fractal of the annual runoff process in the mainstream of the Tarim River by using the wavelet analysis method and the fractal theory. The main conclusions are as follows: 1) From a large time scale point of view, i.e. the time scale of 16 (24) years, the annual runoff basically shows a slightly decreasing trend as a whole from 1958 to 2005. If the time scale is reduced to 8 (23) or 4 (22) years, the annual runoff still displays the basic trend as the large time scale, but it has fluctuated more obviously during the period. 2) The correlation dimension for the annual runoff process is 3.4307, non-integral, which indicates that the process has both fractal and chaotic characteristics. The correlation dimension is above 3, which means that at least four independent variables are needed to describe the dynamics of the annual runoff process. 3) The Hurst exponent for the first period (1958-1973) is 0.5036, which equals 0.5 approximately and indicates that the annual runoff process is in chaos. The Hurst exponents for the second (1974-1989) and third (1990-2005) periods are both greater than 0.50, which indicate that the annual runoff process showed a long-enduring characteristic in the two periods. The Hurst exponent for the period from 1990 to 2005 indicates that the annual runoff will show a slightly increasing trend in the 16 years after 2005.  相似文献

利用1970年以来沿聊考断裂带及周边50 km范围内的地震数据,结合历史强震与现今地震活动背景,分别运用最大似然法和最小二乘法对研究区进行b值计算,圈出高应力累积区,并借助时间相依的地震潜势概率评估方法以及地震活动性分布,得出以下结论:1)南段的范县、清丰、濮阳以及鄄城地区的b值维持在0.6~07之间,属于高应力积累区;2)未来50 a内南段危险性较高,100 a内整条断裂发生M5.0~6.0地震的可能性较大;3)地震活动主要集中在115.2°~115.6°E、34.9°~36°N区域内,且自2000年后地震活动性变强。  相似文献
