Despite the potential of this method for deformation monitoring, the quality description of InSAR timeseries in terms of precision and noise structure and, consequently, the precision description of the InSAR-derived parameters (e.g., displacement and its velocity) are still somewhat ambiguous. In this paper, we propose a data-derived methodology that directly estimates the precision and noise structure of the final InSAR products, using Least Squares Variance Component Estimation (LS-VCE). Note that due to the spatial correlation among adjacent coherent pixels and adjacent acquisitions, a multivariate LS-VCE model should be applied. We used the proposed method on deformation timeseries derived from the Sentine-l data over city of Tehran, Iran. The results show that applying the multivariate LS-VCE method in our case study improves the results by about 50% compared with the case where the noise parameters are not considered. In addition, the results confirm that InSAR timeseries are highly correlated in time and space. Particularly, the spatial correlation between a series of neighbouring targets for the noise components is significant and gradually decreases with increasing arc length. It should be noted that the observed spatial correlation should be differentiated from the well-known spatial correlation imposed by atmospheric components. In fact, due to the atmosphere filtering step, the noise structure of the final results will be different from the statistical characteristics of a raw atmospheric signal. The proposed methodology is not case study dependent and can be used as an appropriate approach to provide the precision (as a quality descriptor) of the timeseries InSAR products.","PeriodicalId":50766,"journal":{"name":"Annals of Geophysics","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2022-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80967504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, different disturbing components perturb the recorded strain signal. These disturbances can mask ultra-small strain changes related to volcano activity and thus need to be filtered in order to accurately monitor volcano deformation. We developed the software STRALERT (STRain and wArning signaLs in nEar Real-Time) to provide both the recorded and the filtered strain signals in near real-time to the Surveillance Room of the “Istituto Nazionale di Geofisica e Vulcanologia – Osservatorio Etneo” which monitors the Etna activity. The software encloses a modified version of the code BAYTAP-G for filtering the incoming signal from the continuously running strainmeter at Etna. Thanks to the appropriate and robust signal filtering, STRALERT is capable to provide anefficient estimate of transient strain changes, which concur in tracing volcano deformation and detecting the onset and the conclusion of eruptive events. Our findings demonstrate the important contribution of STRALERT for volcano surveillance operations.","PeriodicalId":50766,"journal":{"name":"Annals of Geophysics","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2022-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91221126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The work touches upon an urgent problem of ensuring the stability of high-rise buildings under seismic load and preventing their destruction. A mathematical model has been built to investigate the effect of seismic activity on high-rise buildings in the Sichuan province (China). Pearson’s test was used to compare the statistical dependence between variables in the study period. Values with a statistical significance of p ≤ 0.05 were considered statistically significant. The probability of earthquakes of 8 magnitude and above was found to be 5% with a frequency of recurrence of 3900 ± 400 yrs, p ≤ 0.001. The paper presents the technique of refractive geophysical research. The seismic reliability index was n = 3.2 at t = 5 s. The standard deviation was 2% and the χ2 statistic was 0.95. The overall (0.59, or 59%) and conditional (0.06, or 6%) risks of failure under seismic load were calculated for high-rise buildings with a service life of 100 years. The coefficients of seismic activity were as follows: 3.203 at the conditional risk level of 5%; 2.97 at the conditional risk level of 10%; and 2.523 at the conditional risk level of 30%.","PeriodicalId":50766,"journal":{"name":"Annals of Geophysics","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2022-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88242248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Earthquakes respond to complex natural systems whose mechanical properties evolve over time. Thus, in order to understand the multi-scale, physical/chemical processes responsible for the faulting that earthquakes occur on, it is required to consider phenomena that intersect different research fields, i.e., to put in place multidisciplinary monitoring. Hence, NFOs are grounded on modern and multidisciplinary infrastructures, collecting near fault high resolution raw data that allows generation of innovative scientific products. The NFOs usually complement regional backbone networks with a higher density distribution of seismic, geodetic, geochemical and other geophysical sensors, at surface and sometimes below grade. These dense and modern networks of multi-parametric sensors are sited at and around active faults, where moderate to large earthquakes have occurred in the past and are expected in the future. They continuously monitor the underlying Earth instability processes over a broad time interval. Data collected at each NFO results in an exceptionally high degree of knowledge of the geometry and parameters characterizing the local geological faults and their deformation pattern. The novel data produced by the NFO community is aggregated in EPOS and is made available to a diverse set of stakeholders through the NFO Federated Specific Data Gateway (FRIDGE). In the broader domain of the Solid Earth sciences, NFOs meet the growing expectations of the learning and communication sectors by hosting a large variety of scientific information about earthquakes as a natural phenomenon and a societal issue. It represents the EPOS concept and objective of aggregating and harmonising the European research infrastructures capabilities to facilitate broader scientific opportunity. The NFOs are at the cutting edge of network monitoring. They conduct multidisciplinary experiments for testing multi-sensor stations, as well as realise robust and ultra-low latency, transmission systems that can routinely accommodate temporary monitoring densification. The effort to continuously upgrade the technological efficiency of monitoring systems positions the NFO at the centre of marketing opportunities for the European enterprises devoted to new sensor technology. The NFOs constitute ideal test beds for generating expertise on data integration, creating tools for the next generation of multidisciplinary research, routine data analysis and data visualization. In particular focus is often on near-real time tools and triggering alarms at different levels are tested and implemented, strengthening the cooperation with the Agencies for risk management.

Anthropogenic seismicity, i.e. the undesired dynamic rock mass response to geo-resources exploitation, is one of the examples of unwanted by-products of the technological operation of humans. The socio-economic impact of the induced seismicity is very significant. Induced earthquakes can cause material loss, injuries and even fatalities. Restricted access to data constitutes a barrier to assessing and mitigating the associated hazards. To respond to the need of the scientific community the Thematic Core Service Anthropogenic Hazards (TCS AH) has been created within the framework of the European Plate Observing System, a solid earth science European Research Infrastructure Consortium (ERIC). TCS AH is an open consortium of 13 European institutions. TCS AH provides access to a novel e-research infrastructure, the EPISODES Platform (former name: IS-EPOS platform) to foster both research and training on induced seismicity and geo-hazards related to the exploration and exploitation of geo-resources. The EPISODES Platform is connected to international data nodes which offer open access to multidisciplinary datasets, called episodes. Episodes comprise geoscientific and associated data from industrial activity along with a large set of embedded applications for their efficient data processing, analysis and visualization. The EPISODES Platform opens also the possibility to create new applications and combine implemented applications with the user's codes. The team-working features of the EPISODES Platform facilitate collaborative and interdisciplinary scientific research, public understanding of science, citizen science applications, knowledge dissemination, and the teaching of anthropogenic hazards related to geo-resource exploitation. This study presents the current results of the TCS AH research infrastructure integration and also indicates the benefits of their usage for science, education, and innovation.","PeriodicalId":50766,"journal":{"name":"Annals of Geophysics","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2022-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81056062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
