Volcán de Colima is a highly active stratovolcano in western Mexico which presents a significant hazard to over 300,000 people who live within ca 40 km of the volcano. Due to its persistent activity, the volcano is actively monitored and researched, and understanding the patterns of behaviour is vital to accurate hazard assessment. Sentinel-1 SAR images from ascending and descending orbits allow 1D and 2D ground motions to be retrieved using multi-interferogram techniques. SqueeSAR ® ’s unique processing allows a better characterisation of subtle ground movements in remote, rural mountainous areas compared to many other multi-interferogram techniques. A dataset of 147 SAR scenes (2017-2019) has been processed to show patterns of lava subsidence (<150 mm of downward vertical deformation over 2 years), as well as volcano deflation and apparent westward lateral movement. These data indicate that viscous andesitic lava flows may remain mobile for years following eruption and emplacement, and that the entire volcanic edifice is subsiding. Despite the apparent quiescence, volcanic edifices can remain highly dynamic after the termination of explosive or effusive activity. We interpret that the western flank of Volcán de Colima may become steeper with time and may be of long-term concern for hazard assessment activities.

Volcán de Colima是墨西哥西部一个高度活跃的层状火山，对居住在火山40公里范围内的30多万人构成了重大威胁。由于火山的持续活动，人们对其进行了积极的监测和研究，了解其行为模式对准确的危害评估至关重要。Sentinel-1从上升和下降轨道获取的SAR图像允许使用多重干涉图技术检索1D和2D地面运动。与许多其他多重干涉图技术相比，SqueeSAR®独特的处理方法可以更好地表征偏远农村山区的细微地面运动。对147个SAR场景(2017-2019)的数据集进行了处理，显示了熔岩沉降(2年内垂直向下变形<150 mm)、火山收缩和明显的西向横向移动的模式。这些数据表明，黏稠的安山岩熔岩流可能在喷发和就位后的数年内保持流动，整个火山大厦正在下沉。尽管表面上是静止的，但火山大厦在爆发或喷发活动结束后仍能保持高度动态。我们解释说，Volcán de Colima的西翼可能会随着时间的推移而变得更陡峭，并且可能是危害评估活动的长期关注。专题合集:本文是地球和其他行星现场调查遥感合集的一部分，可在:https://www.lyellcollection.org/topic/collections/remote-sensing-for-site-investigations-on-earth-and-other-planets上获得

A thorough review paper on hydrogeology topics is challenging, as since the 1990s there has been a substantial increase in published papers and reports. It appears that Medici and West (2022), in keeping a reasonable length to their paper, have only reviewed selected parts of the sandstone stratigraphy comprising the principal sandstone aquifers of the UK. Much of the focus of their review is on the Triassic Sherwood Sandstone aquifers of the north-west of England.

A typical multi-stage structural surfaces landslide mass is located in Sichuan Province, Southwest China, is used as the research object. Based on the site survey and related data collection and analysis, the topography, geomorphology, stratigraphic lithology, and geological structure of the study area were identified, and the engineering geological conditions and signs of deformation and damage of the landslide mass were analyzed and studied. The stability characteristics of four different levels of structural sliding surfaces on the main section of the landslide mass under natural condition, condition of rainstorm, and condition of earthquake were comprehensively analyzed using the transfer coefficient method and Geo5 geotechnical analysis software. The results show that the stability of the four sliding surfaces ( ab, bc, ad , and ae ) of the landslide mass is basically stable, basically stable, stable, and stable under natural condition; basically stable, less stable, stable, and stable under condition of earthquake; and less stable, unstable, stable, and stable under condition of rainstorm. It is found that the stability of the above two slip surfaces is relatively poor. Then, the anchor support design was chosen to reinforce the landslide mass, and the stability of the supported landslide mass was verified by Geo5 software.

When the opportunity to review this book came up I jumped at the chance. The book is edited by Ameratunga, A., Sivakugan, N and Das, B.M. I have several books by Das and this one did not disappoint. The coverage is thorough and comprehensive while at the same time clearly and simply explained. The book primarily covers ground improvement in soft clays but covers so much else besides. It would be of interest to all, easy enough to read for students but informative enough for practitioners. Chapter 2 covers the engineering geology of soft clay as part of the importance of the ground model including a discussion around different kinds of ground model. A summary of basic soil mechanics in chapter 3 flows logically into the geotechnical testing (Chapter 4) and then derivation of the design parameters, all applicable to the design of ground improvement in soft clays.
当有机会评论这本书时，我立刻抓住了这个机会。这本书是由Ameratunga, A.， Sivakugan, N .和Das, B.M.编辑的。我有几本Das的书，这本书没有让人失望。内容全面透彻，同时解释清楚，简明扼要。这本书主要介绍了软粘土的地基改良，但除此之外还介绍了许多其他内容。它对所有人都有兴趣，对学生来说足够容易阅读，但对从业者来说足够翔实。第2章介绍了软粘土的工程地质，作为地基模型重要性的一部分，包括对不同类型地基模型的讨论。第3章对基础土力学的总结顺理成地进入到岩土试验(第4章)，然后推导出设计参数，所有这些都适用于软粘土地基改良设计。

A drying-saturation cyclic water-rock interaction test simulating the periodic fluctuation process of reservoir water level was designed. The results show that: (1) With the increase of the number of cycles, the compressive strength of sandstone joint gradually decreases. The compressive strength of the first four cycles decreases rapidly and the deterioration effect is obvious. As the joint dip angle increases, the compressive strength of the sandstone joint showing a U-shaped distribution. (2) With the increase of the number of cycles, the elastic modulus of the sandstone joint gradually decreases. With the increase of the joint inclination angle, the elastic modulus showing a "V-shaped" change trend. (3) With the increase of the number of cycles, the brittleness of the sample is obviously weakened, showing the characteristics of looseness and weakness. With the increase of joint inclination, the failure mode of the sample gradually changes from tensile failure to tensile shear failure to tensile failure. (4) The mechanical properties of intermittent sandstone joint under the action of circulating water-rock have obvious deterioration effects, which are the result of physical, chemical, and mechanical actions occurring inside the sandstone joint.

The Banjarnegara–Jemblung Landslide was triggered on December 12th 2014 near the village of Jemblung in Central Java (Indonesia). The disaster occurred on the northern slope of Mount Gunung Telagalele and caused more than 100 fatalities, leading to the most disastrous landslide in Indonesia during the last decades. The event is characterized by multiple slope failures forming two landslide events A and B, with two connected scarps but two separated runout paths. According to eyewitnesses, landslide A was mobilized only a few minutes after the initial failure of B. Initially, both landslides began as earth slides which subsequently developed into very to extremely rapid earth flows. Although the failure volume was moderate, both slide-flows reached very high velocities of several m/s and long travel distances, leading to remarkable low travel angles of 14 and 15°. Field investigations confirm that slope failure was favoured by geological predisposition based on a slope-parallel layering of volcaniclastic sediments of different origin and age, as well as intensive tropical weathering generating clay-rich soils. Temporal relationships as well as stability analysis indicate that antecedent rainfall over two months and heavy rainfall the day before was triggering the slope failure.

Bangarnegara–Jemblung滑坡于2014年12月12日在中爪哇（印度尼西亚）的Jemblung村附近引发。这场灾难发生在古农特拉加莱山北坡，造成100多人死亡，导致印尼发生了过去几十年来最严重的山体滑坡。该事件的特征是多个斜坡破坏形成两个滑坡事件A和B，两个连接的陡崖但两个分离的跳动路径。据目击者称，山体滑坡A在B最初发生故障后仅几分钟就被动员起来。最初，两次山体滑坡都是以滑坡开始的，随后发展成非常迅速的泥石流。尽管破坏量适中，但两种滑动流都达到了几m/s的非常高的速度和很长的行程距离，导致了14°和15°的显著低行程角。现场调查证实，基于不同来源和年龄的火山碎屑沉积物的斜坡平行分层，以及产生强烈热带风化的富含粘土的土壤，地质倾向有利于斜坡破坏。时间关系和稳定性分析表明，两个月以上的前期降雨和前一天的强降雨是引发边坡破坏的原因。专题集：本文是Leading to innovative engineering Geologics practices系列的一部分，可在以下网站获取：https://www.lyellcollection.org/topic/collections/leading-to-innovative-engineering-geology-practices

Characterizing the spatial distributions of hydraulic conductivity of rock mass is important in geoscience and engineering disciplines. In this paper, the architecture of CNN is proposed to predict the spatial distributions of hydraulic conductivity based on limited geologic factors. The performance of CNN model is evaluated using the new data of hydraulic conductivity. A comparative study with the empirical method is performed to validate the reliability of CNN model. The effect of weathering and unloading on the spatial distributions of hydraulic conductivity is studied using the CNN model. The result shows that the hydraulic conductivity predicted by CNN model is within the error range of 5% compared to the Lugeon borehole tests. The predictive accuracy of the CNN method is higher than the estimations of the empirical relations. The spatial distributions of hydraulic conductivity versus depth can be divided into three stages. At first stage, the hydraulic conductivity is slightly reduced with the increasing of depth. Increasing to the depth range of 300-600 m (second stage), the hydraulic conductivity is slightly reduced as a function of lower weathering degree. At last stage, the hydraulic conductivity is not changed by the weathering, and converge to a constant with the depth increasing.
