“…Specified were the regularities of formation and criteria of predicting of gold-ore sites of unconventional gold-sulphide vein-embedded type, represented by the industrial Suzdal deposit and promising small deposits and ore occurrences (Zhaima, Mirazh, Baibura and others) [16][17][18][19][20]. According to their genesis, these deposits are referred to the hydrothermalmetasomatic type, formed in the Hercynian cycle under collisional geodynamic environment (С2-3-С3), localized in the Zaisan sutural zone and of a significant material value [4,8].…”

The region under consideration is part of the Central Asian mobile belt system, organized by a large geo structure of the Greater Altai (GA), which integrates geological structures of the Rudny Altai, Kalba, Zharma-Saur and adjacent districts of Russia and China. The regional goldore sites vary by ore formation types, age, geological formation conditions and mineralization scale. The largest among them are the Ridder-Sokolny gold-polymetallic deposit in the Rudny Altai and the Bakyrchik deposit of the gold-sulphide-carbonaceous type in West Kalba, comparable in many ways with the world sites of Sukhoi Log and MurynTau in the black shale strata. In recent years, much attention was paid to prediction and assessment of the unconventional (apocarbonate) goldsulphide type of mineralization, associated with the island volcanic-carbonate-terrigenous formation С1v2-3 (the Suzdal deposit and others). The present paper considers new results acquired from the studies of the gold-ore sites of the Suzdal type.

“…About 290 significant natural hazards were reported over the last 30 years [2]. Also, Indonesian is located at the meeting points of the earth's tectonic plates where the Eurasian plate in the west and south side, then Philippine sea plate on the east side, [3]. Therefore, this country is geographically vulnerable to natural hazards or disaster such as the earthquake, landslides, and volcanoes, [4,5].…”

Indonesia is located along the Pacific Ring of Fire and close to some natural hazards, including earthquakes, tsunamis, volcanic eruptions, flooding, and droughts. BNPB (the National Agency for Disaster Management) recorded 436 deaths, 1353 mild injuries, 783 serious injuries, and 77,975 houses also, and schools were damaged. It is important to build awareness of disaster and culture of disaster risk reduction. This article provides information about how to build a culture of alertness and safety in schools by developing a network of fellow stakeholders in the field of disaster management in Indonesia. Therefore, a conceptual framework for schools-based disaster preparedness should be provided. Preparation, resources, simulation, and promotion phases for health policy-makers are the important aspects of school-based disaster preparedness in Indonesia. Many countries have successfully implemented a school-based disaster preparedness strategy. The information about this program is expected to build preparedness in the future, as well as prevent the losses of life and property from the future hazardous event.

Pore water pressure changes due to soil-atmospheric boundary interaction can significantly influence soil behaviour and can negatively affect the safety and stability of geotechnical structures. For example, prolonged rainfall events can lead to increased pore water pressure and lower strength; repeated cycles of pore water pressure changes can lead to degradation of strength. These effects are likely to become more severe in the future due to climate change in many parts of the world. To analyse the behaviour of soil subjected to atmospheric boundary interactions, several parameters are needed, and hydraulic conductivity is one of the more important and is difficult to determine. Hydraulic conductivity deduced from laboratory tests are often different from those from the field tests, sometimes by orders of magnitude. The problem becomes even more complicated when the soil state is unsaturated, where the hydraulic conductivity varies with the soil's state of saturation. In this paper, a relatively simple alternative approach is presented for the estimation of the hydraulic conductivity of unsaturated soils. The method involved a systematic re-analysis of observed pore water pressure response in the field. Using a finite element software, the soil-atmospheric boundary interaction and related saturated/unsaturated seepage of an instrumented slope have been analysed, and results are compared with field measurements. The numerical model could capture the development of suction, positive pore water pressure and changes in water content with reasonable accuracy and demonstrated the usefulness of the hydraulic conductivity estimation method discussed in this paper.
