This event, taking into account the magnitude of the atmospheric pressure waves, is comparable only to the Krakatoa eruption of 1883. To compare both eruptive sequences, a method similar to the analysis of the timing of the arrival of multiple phases at barometric stations, as reported in (Strachey, R., Stokes G.G., Scott, R.H. (1888). On the air waves and sound caused by the Krakatoa eruption of August 1883, in “The eruption of Krakatoa and subsequent phenomena,” Symons, G. J. (ed.). Report of the Krakatoa Committee of the Royal Society (Trübner and Co., London)) for Krakatoa, was used. Since the HTHH volcanic event gave rise to the only volcanic pressure wave known to have circled within the Earth’s atmosphere multiple times in the last 139 years, it is of interest to perform similar timing statistics on the multiple passages of the waves at stations that recorded them. A review of the Krakatoa analysis and a comparison with the HTHH are presented, with possible implications on the physical parameters affecting its speed of propagation. Changes in the global state of the atmosphere during the interval between the two events may also explain some of the differences observed.","PeriodicalId":21078,"journal":{"name":"pure and applied geophysics","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141168137","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 pore structure refers to the geometric shape, size, spatial distribution and interconnectedness of pores, microcracks and throats. It is closely related to the storage space of reservoirs and the spatial distribution of oil/gas. Understanding the pore structure is crucial for the development of processes to increase oil/gas production capacity. Six dolomite samples from the Gaoshiti-Moxi Longwangmiao Formation are sorted out for measurements, and the ultrasonic and seismic attenuation are determined by using the spectral ratio method and the enhanced frequency shift method, respectively. When predicting the pore structure, we assume that the aspect ratio and volume fraction of pores and microcracks correspond to a normal distribution. On this basis, a model with the Voigt–Reuss–Hill average (VRH), differential effective medium (DEM) theory and infinituple-porosity media (IPM) theory is proposed. The acoustic wave responses in terms of reservoir porosity and standard deviation of normal distribution are analyzed, and multiscale 3D rock physics templates (RPT) are created. The calibrations of the templates are performed with the ultrasonic and seismic data, and then the templates are applied to the field data. The results show that the estimated porosity and pore structure (corresponding to the mean aspect ratio and standard deviation of a normal distribution, respectively) are in substantial agreement with the log data and the actual gas production results.</div>","PeriodicalId":21078,"journal":{"name":"pure and applied geophysics","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141152104","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}

These locations are now impossible to find from the ground surface due to the urban development of New Cairo. In this study, a subterranean landfill site near the Ring Road in East Cairo, Egypt, was found and delineated using electrical resistivity tomography (ERT) data and multi-temporal high-resolution satellite imagery. Up to 2005, the research location was a WNW-oriented quarry that had been randomly filled with diverse solid materials, according to an analysis of changes shown on the satellite images. Based on the change detection data, ERT survey planning was done. The ERT measurements identified the infill material-occupied electrically conductive zones on the plan view and separated them from the resistive zones, representing the natural soil areas. Two distinct geoelectrical units could be distinguished by combining the satellite images and the ERT results: Unit-2 (the lower unit) is characterized by high resistivity values that characterize the original soil (bedrock), whereas Unit-1 (the upper unit) is defined by low to moderate resistivity values that are the solid waste materials. The contact between the bedrock and the infill materials was mapped and delineated using the closely spaced grid of ERT profiles and the thorough topographic map. Ground surface elevation, the depth of Unit 1’s lower boundary, and this unit’s thickness change throughout the researched site are some criteria that might be addressed and used to characterize the unit of interest (Unit 1).</div>","PeriodicalId":21078,"journal":{"name":"pure and applied geophysics","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141105288","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}

Six indices namely, Monthly maximum value of daily maximum temperature (TXx), Monthly maximum value of daily minimum temperature (TNx), Monthly minimum value of daily maximum temperature (TXn), Monthly minimum value of daily minimum temperature (TNn), Percentage of days when maximum temperature > 90th percentile (TX90p) and minimum temperature > 90th percentile (TN90p) have been utilized to assess the changes in temperature extremes.

Increasing TN90p frequency has been found over Sikkim, Bihar, and North Bengal while it has decreased over Chhattisgarh and Odisha.
