The Liaodong and Jiaodong regions have similar tectonic backgrounds and geological evolution histories. However, the confirmed gold resources in the Liaodong region are only one-tenth of those in Jiaodong. To reveal the controlling factors behind the differences in mineralization between these two regions and explore the deep mineralization prospects in the Liaodong region, we conducted a short-period and high-density array (WSP array) in the Wulong Gold Concentrated Area, the largest goldfield in the Liaodong region. Using data recorded by 334 SmartSolo seismometers for one month, we applied ambient noise tomography to obtain the S-wave velocity structure of the crust down to a depth of 3.5 km beneath the Wulong goldfield. The velocity structure revealed the presence of two sets of low-velocity anomalies trending NNE and NW, respectively, in the shallow crust (shallower than 1.5 km) of the Wulong goldfield, while two high-velocity anomalies were identified at deeper depths (1.5–3.5 km). By combining these findings with the geological characteristics of the Wulong goldfield, it was discovered that the high-velocity anomaly (II) corresponds to the Sanguliu granitic body exposed at the surface, while the high-velocity anomaly (I) could be a concealed intrusive body. The shallow low-velocity anomalies are the result of hydrothermal alteration caused by mineralizing fluids along the NNE- and NW-trending faults. The intersection of these two sets of faults, where the low-velocity anomalies exist, represents the center of the hydrothermal activities. Based on these observations, it is proposed that the area between the Sanguliu granitic body and the concealed intrusive body in the northwest has favorable metallogenic conditions. The intersections of the NNE- and NW-trending faults show the high potential for forming large to super-large altered rock-type gold deposits.</p></div>","PeriodicalId":21078,"journal":{"name":"pure and applied geophysics","volume":"181 9","pages":"2973 - 2990"},"PeriodicalIF":1.9,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226669","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 deposition of tsunamis on land is extremely complex, involving contributions from both the hydrodynamics of tsunami flow propagation and the characteristics of the tsunami, as well as topographical conditions. In both local and detailed contexts, artificial structures can affect the formation of tsunami deposits. In this study, we focused on the effect of artificial structures on the characteristics of the 2018 Anak Krakatau tsunami deposits. Field observations showed that the remains of dikes, houses and asphalt roads significantly influenced the source, thickness, structure of tsunami deposits and grain size parameters. Tsunami deposits consisting of fine-grained material originated from the sediment on the seafloor. Tsunami deposits were thicker in areas closer to the part of the sea unaffected by artificial structures and exhibited a thinning trend inland. In general, the grain size of tsunami deposits is coarser than that of pre-tsunami deposits. Tsunami deposits predominantly exhibit an upward fining trend. Our study explains the key role of artificial structures in the formation of tsunami deposits and the sediment structure produced in coastal areas. A drastic change in the characteristics of the grain size parameters results from the presence of artificial structures. Overall, the tsunami deposit layers could have been better sorted. Significantly different sortation values were observed at sites located above the asphalt road. Similarly, kurtosis values showed an anomaly. The skewness value was inversely proportional to the average grain size in areas affected by artificial structures.</p></div>","PeriodicalId":21078,"journal":{"name":"pure and applied geophysics","volume":"181 10","pages":"2991 - 3003"},"PeriodicalIF":1.9,"publicationDate":"2024-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142209910","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}

We investigate the mean annual water temperature trends at the confluence of the Sava and Danube Rivers, along with air temperature trends at the Belgrade meteorological station, spanning from 1956 to 2020. Results reveal a consistent increase in temperature across all three measuring stations, with the Danube experiencing a rise of 0.34 °C/decade, the Sava at 0.44 °C/decade, and Belgrade's air temperature increasing by 0.39 °C/decade. Employing the Rescaled Adjusted Partial Sums method, sharp rises in water temperature were pinpointed in 1989 for the Sava and 1990 for the Danube, while Belgrade's air temperature surge began in 1998. The highest intensity of air temperature increase within the recent period (1998–2020) was observed at the Belgrade observatory, reaching 0.76 °C/decade. Notably, the Sava exhibited a faster increase in water temperature over the last thirty years compared to the Danube. August marked the peak average water temperature for both rivers, while July recorded the highest average air temperature in Belgrade. Despite differing flow rates, both rivers exhibit similar hydrological regimes, with maximum flows occurring in April and minimum flows in August for the Sava, and October for the Danube. Seasonal temperature increases were most pronounced in summer, notably in August, with the smallest rises occurring during cold periods. Additionally, an inverse proportional relationship between mean annual water temperatures and discharges was observed at both river stations. The overall findings suggest that the increase in both air and water temperatures is more pronounced during the warmer part of the year.</p></div>","PeriodicalId":21078,"journal":{"name":"pure and applied geophysics","volume":"181 9","pages":"2895 - 2912"},"PeriodicalIF":1.9,"publicationDate":"2024-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00024-024-03552-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142209911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the past, it can be said that changes in climate were caused by natural causes, while today they are largely caused by human activities. Turkey is among the countries that will be affected by climate change. Therefore, In this study, a stochastic time series model was constructed to forecast the precipitation and temperature data of Turkey between 2020 and 2050. Seasonal Autoregressive Integrated Moving Average models were used to take into account the relationship between the data and seasonality factors. In addition, the most appropriate model for each station was established separately. The accuracy of the predicted data was tested by correlation test (r) and root mean square error (RMSE) test. As a result of the study, the average r value for temperature data was 99% and RMSE value was calculated as 1.46. For precipitation data, the average r value was calculated as 66% and RMSE value as 34.6. In addition, in this study, drought models for Turkey until 2050 were established and spatial and temporal evaluation of these models were made. These models were obtained by analyzing the data of uniformly distributed stations over Turkey between 1990 and 2050 with standard precipitation evapotranspiration index (SPEI). Different time scales (SPEI₃, SPEI₆, SPEI₉ and SPEI₁₂) were used in drought analysis. As a result of this study, drought return interval maps of Turkey and drought maps between 1990 and 2050 were created.</p></div>","PeriodicalId":21078,"journal":{"name":"pure and applied geophysics","volume":"181 9","pages":"2913 - 2933"},"PeriodicalIF":1.9,"publicationDate":"2024-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142209931","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}

This study aimed to test the UK Seismological Network Broadband Seismic Stations to calculate the P-wave moment magnitude (M_<b>wp</b>) using teleseismic waves. The standard way to calculate the M_<b>wp</b> is using the P-wave portion of a seismic wave recorded at different epicentral distances.

We simplified the selection of a P-wave portion of seismic waves using a theoretical formula that works with epicentral distance, P-wave arrival time and an apparent P-wave velocity, which calculates the S-wave arrival time. The results show the variation between the Harvard centroid moment tensor (CMT—M_<b>w</b>) and M_<b>wp,</b> which is about ± 0.1 magnitude units in most events and ± 0.2 for some events.

In this study, five member ensembles for Cloud Microphysics (CMP) and Land Surface Model (LSM, conventional ensemble) are created, as well as an ensemble of the top five performing members (optimized ensemble) for 13 Monsoon Depressions (MD) and 8 Deep Depression (DD) cases.

WRF 4.1 is used to carry out simulations, which are initialized with ERA5 reanalysis data and have a 72-h lead time. Rainfall verification skill scores indicate that ensemble members perform significantly better than any deterministic model. Rainfall characteristics such as location, intensity, and time of occurrence are well predicted in ensemble members as measured by a higher correlation coefficient and a lower RMSE. Neighbourhood ensemble probability also demonstrates that ensemble members have a higher chance of detecting heavy to very heavy rainfall events with more spatial accuracy. The study also concludes that choice of parameterization also affects large-scale dynamical parameters (temperature, humidity, wind, hydrometeors) and thus associated rainfall. Ensemble members exhibited less bias in the composite analysis of large-scale parameters.
