Bouguer Anomaly Map

SUMMARY Lusi is a sediment-hosted hydrothermal system located near Sidoarjo in Central Java, Indonesia, and has erupted continuously since May 2006. This mud eruption extends over a surface of ∼7 km2, and is framed by high containment dams. The present study investigates the geometry of the subsurface structures using a detailed gravimetric model to visualize in 3-D the Lusi system and surrounding lithologies. The obtained residual Bouguer anomaly map, simulated through geostatistical interpolation methods, supports the results of previous deformation studies. The negative gravity anomaly zones identified at Lusi are interpreted as fractured areas through which fluids can ascend towards the surface. A 3-D detailed geological model of the area was constructed with Geomodeller™ to highlight the main features. This model relies on the structures’ density contrasts, the interpreted residual Bouguer anomaly map, and geological data from previous authors. 3-D algorithms were used to calculate the gravity response of the model and validate it by inverse methods. The final output is a gravity constrained 3-D geological model of the Lusi mud edifice. These results provide essential details on the Lusi subsurface and may be useful for possible future geothermal resource exploitation and for the risk mitigation plans related to the maintenance of the man-made framing embankment.

Simple observation of events for the disaster in Indonesia is almost always showed the same picture is a condition in which reactive attitude and spontaneous, unplanned as shown by society and government. There is a general tendency that people do not know how to act or addressing disaster. Regional preparedness in the face of natural disasters is very important. Slamet mountain with an altitude of 3,428 meters above sea level is the highest mountain in Central Java and the second highest in Java. Population data in the area of Mount Slamet and surrounding areas are included in Kawasan Rawan Bencana (disaster-prone areas) is approximately 215 953 inhabitants. Seeing the extent of the area affected by the eruption of Mount Slamet threats can not be taken lightly. This study aimed to explore the networking model for effective disaster risk reduction in disaster-prone areas of Mount Slamet. Networking model for disaster risk reduction is a very important information in order to overcome the impact of the eruption of Mount Slamet.

Post Disaster

Infrastructures are connected between themselves and their connections form a complex network. Disaster impacted infrastructures have a reduced level of serviceability. The impact of the reduction of serviceability of disaster-affected infrastructures cascades through the entire infrastructure network. The recovery capacity of the network governs the recovery curve of a disaster-impacted infrastructure network system. Moreover, the speed of recovery of the infrastructure network from a post-disaster condition to the pre-disaster condition dictates the resilience of the system. Building these capacities requires spending money. The extent of resilience that can be afforded under a given budget situation is termed as the feasible resilience. This paper presents a framework for planning the capacities so that the feasible resilience of the network can be maximized under a budget situation. To achieve the said objective, the recovery time of a disaster-affected infrastructure network has been minimized. The outcome is the optimal restorative capacities the network needs to have so that the feasible resilience is maximized under a specified budget condition. The outcomes can be used by the decision-makers in natural disaster risk mitigation planning.

Purpose The purpose of this paper is to develop an integrated multi-risk identification procedure for World Cultural Heritage (WCH) sites exposed to seismic events, while considering characteristics of disasters from earthquakes in a multi-hazard context on one side and particular aspects of WCH (e.g. outstanding universal values and associated condition of authenticity and integrity) on the other. Design/methodology/approach An interdisciplinary review of current relevant approaches, methods, and practices is conducted through the existing literature of disaster risk management, heritage conservation, and seismology. Furthermore, a document analysis of concrete cases affected by seismic events supports concepts and the procedure. Findings This paper results in a methodology of identifying multi-risk of disasters induced by earthquakes. A bow-tie analysis diagram in combination with a risk identification matrix is developed for illustrating a multiple emergency scenario in identifying possible impacts of earthquakes’ primary effects, secondary hazards, and human-threats on tangible and intangible attributes of cultural properties. Practical implications The research aims to provide specialists and practitioners from multiple sectors engaged in pre-disaster risk mitigation and preparedness plan for cultural heritage with a practical risk identification tool. The proposed method, in a multiple hazard context, intends to enhance risk assessment procedure for determining more appropriate risk reduction strategies in the decision-making process. Originality/value This paper, through emphasising “earthquake disaster risk” rather than “earthquake risk”, illuminates the significance of quake-followed secondary hazards, potential human-induced hazards and human errors in the risk identification process, due to the fact that while a disaster may begin with a quake, its full scope might be triggered by a combination of the mentioned potential threats.

Environment Sustainability

Telaga Warna and Telaga Pengilon are two volcanic lakes in the Dieng Plateau offer some unique phenomena which are interested for tourists to visit. Telaga Warna and Telaga Pengilon are located side by side in the Dieng Palteau. Those two lakes also have specific ecosystem which differ to other lakes. However as land use in the surrounding area is now gradually changing, the lake is now facing to environmental degradation. The land use in the surrounding area is for intensive agricultural which main crops are vegetable, especially potatoes. Meanwhile, the number of tourist visiting those two lakes is increasing; it may also give some impact to the lake environment. This research aims to study the impacts of agricultural practices and tourism activities to the lake environmental which lead to the environment sustainability of the lakes. The field survey was conducted to collect some data on lakes characteristics, agricultural and tourism activities. Some interviews to local people and tourists were also conducted. Some water and sediment samples were collected followed by laboratory analyses. Some secondary data from previous study was also collected. Data analysis was conducted based on qualitative and quantitative techniques. The study found that agricultural practices of potatoes plantation uses water from the Telaga Pengilon to irrigate the plant by pumping out the water using water pump and distributes the water over the plantation area. Agricultural practices lead to soil erosion, which contribute sediment to the lake carried by surface runoff. Therefore, the volume of lakes is gradually decreasing. The use of fertilizer in the agricultural practice contribute nutrient into the lake carried by surface runoff, leading to the eutrophication, due to the excess used of fertilizer. The study concludes that agricultural practices and tourism activities have some positive economic impacts to the local community, however it also give some adverse affects on the lakes, both quantitatively and qualitatively. The volume of lakes is gradually decreasing due to sedimentation. In the long term periods the lake may not be interesting object for tourism.

This paper is focused on the analysis of landslide susceptibility for civil protection purposes. A methodology was developed and applied to support measures aiming at landslide risk mitigation. It is based on GIS and the Weight of Evidence (WofE) method, which was preferred among several other statistical approaches because it is suitable for large areas, easy to interpret and simple to program. The latter feature is important for implementing a GIS tool aimed to facilitate Civil Protection in the updating of susceptibility maps. An application of the methodology was performed in a mountainous and hilly area of the Northern Apennines (Italy) located in the Province of Modena where landslides are a critical issue in terms of civil protection due to the recurrent damages to buildings, roads and infrastructures. According to the Region Emilia-Romagna Landslide Inventory Map (RER LIM), shallow slides and earth flows are by far the most widespread mass movement types. Hence, the susceptibility assessment concerned these two types of movements. The choice of the training set, based on active landslides, took into account possible limitations of the input data. The predisposing factors were lithology, slope, curvature, Slope Position Index, aspect, land use, distance from roads. The validation was conducted through the PRC and SRC curves, and direct checking (comparison with past occurrences, multi-temporal orthophotos and field surveys). The resulting models predicted the location of landslides in an acceptable manner. One map for each type of landslides was produced and afterwards they were combined in a single document to improve their intelligibility in a civil protection framework.

<em>The phenomenon of forest and land fires (karhutla) in Sumatera always recurs every year. During the dry season, it is necessary to be aware of the emergence of hotspots and be addressed immediately before an actual fire occurs. This study aims to prevent the risk of forest and land fires by applying Weather Modification Technology (TMC). The application of TMC is intended to wet the land (rewetting) so that hotspots do not appear. The research was conducted in Riau, Jambi and South Sumatera Provinces. Research observations were carried out from May to June 2020. The results showed that TMC could increase the intensity of rainfall. The volume of rainwater produced for Riau is 44.1 million m<sup>3</sup> and in Jambi and South Sumatera as much as 50.20 million m<sup>3</sup>. The rainfall that falls is expected to wet the peatlands and fill the peat domes so that TMAT (ground water level) is maintained and soil moisture is maintained. During the implementation of TMC, it was possible to keep the TMAT from dropping more than 40 cm, even for some locations where the TMAT peat measurement had increased.</em>
