In this work,an approach is developed to study the seismicity associated with the impoundment and level changes of a water reservoir(reservoir induced seismicity e RIS).The proposed methodology features a combination of a semi-analytical poroelastic model with an earthquake nucleation approach based on rate-and-state frictional *** combined approach was applied to the case of the Pertusillo Lake,located in the Val d’Agri area(Italy),whose large seasonal water level changes are believed to induce protracted micro-seismicity(local magnitude ML<3).Results show that the lake impoundment in 1962 could have produced up to 0.5 bar(1 bar=100 kPa)changes in Coulomb failure stress(DCFS),while the seasonal water level variation is responsible for variation up to 0.05 *** results of the seismicity rates in 20012014 show that the observed earthquakes are well correlated with the modeled ***,the reason that the seismicity is only observed at southwest of the Pertusillo Lake is provided,which is likely attributed to different rock lithologies and depletion caused by significant hydrocarbon exploitation in the northeastern sector of the lake.

Chinese Medical Journal 2009年第23期122卷 2807-2813页

Background Reportedly, patients with persistent refractory angina due to end-stage coronary artery disease （CAD） not amenable to traditional revascularization techniques have experienced symptomatic relief following laser revascularization, either surgical transmyocardial revascularization （TMR） or percutaneous myocardial revascularization （PMR）. In spite of several hypotheses （i.e., channel patency, placebo effect, denervation, neoangiogenesis）, the mechanism of action and the benefit remains controversial. Methods A prospective trial utilizing positron emission tomography （PET） was conducted as an attempt to correlate quantified myocardial blood flow （MBF） to clinical improvement following PMR. Thirteen consecutive patients with angina class 〉11 in spite of maximal medical treatment underwent PMR with a holmium：yttrium-aluminum-garnet （Ho：YAG） laser. MBF at rest and under hyperemia was assessed by [13N]ammonia PET at baseline, 3 and 6 months following PMR. Results Mean angina class and exercise tolerance time improved at 6 months compared with baseline （P 〈0.001）. The clinical results were accompanied with an improvement in hyperemic MBF （P=-0.05） and a reduction in minimal coronary resistance （MCR; P 〈0.05） in PMR-treated segments. Opposite effects, reduced hyperemic MBF and increased MCR, were observed in nontreated segments. The increase in MCR in nontreated segments revealed the favorable therapeutic impact achieved in PMR-treated segments. Conclusion The results of this trial utilizing a quantitative technique to quantify myocardial perfusion link clinical improvement post-PMR to neoangiogenesis and consistently improved microcirculation.

1992年6月28日的兰德斯地震之前,位于靠近震中北面约11×23×15km体积内曾出现地震活动率下降75％。此异常从1988年1月开始,直至主震发生持续了4.5年,其中包含了各种大小震级的地震。位于震中南面的一个更小的体积(7×14×15 km),从1989年11月开始地震活动率减小75％。同一天发生的大熊地震之前地震活动率下降了100％,这是在围绕震源的一个约13×22×15 km的体积内出现的。在背景期的9年内该体积内包含了192个M≥1.6的地震,但是从1990年12月至1992年6月27日的1.6年内没有一个地震发生。表征这些地震活动率变化的标准偏差z值是很高的,分别为6.3和12.3,说明这些异常是唯一的,在有效性上没有被南加州地震目录(117°06′W至115°40′W和33°45N′至35°10′N)检验到的其它地震活动率的减小所超过。1992年4月23日M=6.1约书亚特里地震的附近地区没有发现地震活动率有变化。根据震级图象和频度-震级分析,我们的结论是,这两个平静异常不可能是由于震级标度的偏移或压缩所致,我们认为它们是前兆异常。这个分析是借助兰德斯地区的已除去群发事件的地震目录,用0.2和0.1校正值(1985年8月和1990年5月)对两个有怀疑的震级偏移进行了修正。我们用新的显示技术将地震活动率作为时间和空间的函数对它的稳定性和变化情形进行了研究。通过对每一时间间隔以及点(纬度、经度)周围的密集网格的范围把地震活动率变化绘制成z值图,则这种计算机程序使活动率变化程度的光滑等值线图作为一个几乎连续的序列而提供出来。因此任何异常,不论人为的还是实际的,都可以精确地确定出来。
