Abstract

Purpose

The purpose of this paper is to offer two Web-based platforms for systematic analysis of seismic processes. Both platforms are designed to analyze and forecast the state of the environment and, in particular, the level of seismic hazard. The first platform analyzes the fields representing the properties of the seismic process; the second platform forecasts strong earthquakes. Earthquake forecasting is based on a new one-class classification method.

Design/methodology/approach

The paper suggests an approach to systematic forecasting of earthquakes and examines the results of tests. This approach is based on a new method of machine learning, called the method of the minimum area of alarm. The method allows to construct a forecast rule that optimizes the probability of detecting target earthquakes in a learning sample set, provided that the area of the alarm zone does not exceed a predetermined one.

Findings

The paper presents two platforms alongside the method of analysis. It was shown that these platforms can be used for systematic analysis of seismic process. By testing of the earthquake forecasting method in several regions, it was shown that the method of the minimum area of alarm has satisfactory forecast quality.

Originality/value

The described technology has two advantages: simplicity of configuration for a new problem area and a combination of interactive easy analysis supported by intuitive operations and a simplified user interface with a detailed, comprehensive analysis of spatio-temporal processes intended for specialists. The method of the minimum area of alarm solves the problem of one-class classification. The method is original. It uses in training the precedents of anomalous objects and statistically takes into account normal objects.

Abstract

Purpose

This paper aims to provide a technical insight into the sensors and systems used to monitor and forecast certain natural hazards.

Design/methodology/approach

Following a short introduction, this paper describes the systems used to monitor and forecast earthquakes, tsunamis, hurricanes and tornadoes. The sensors used in these systems are considered in detail and some experimental techniques are also discussed.

Findings

Numerous national and global systems are used to monitor and predict natural hazards. A wide range of sensors, together with radars and satellite‐based techniques, play a vital role in these. Many new techniques are under study and the most pressing need is for earthquake prediction.

Originality/value

This paper provides a technical review of the role of sensors in natural hazard monitoring and warning systems.

Abstract

Introduces the notion of a dynamic expert system. Shows that by restarting a static expert system periodically it is possible to cope with dynamic environments. This quasi‐static approach to dynamics is suitable if the environment is changing slowly enough in comparison with the inference engine operation and the user reaction time. Implementation of this scheme in “pure” shell meets no difficulties. However, in practice some problems may occur due to the side‐effects in rules and attached procedures. These problems and their relation to classical AI issues are considered in detail. The system was applied to the task of seismology forecast, which contains dynamical factors of both a precise and a heuristic nature. The resulting dynamic expert system never stops, occasionally interrogating the user if it suspects that some of the previously entered data are obsolete. In this sense the computer system behaves as a “live creature”.

Abstract

Purpose

This paper aims to examine the integration of lateral transshipment and road vulnerability into the humanitarian relief chain in light of affected area priority to address equitable distribution and assess the impact of various parameters on the total average inflated distance traveled per relief item.

Design/methodology/approach

After identifying comprehensive critical criteria and subcriteria, a hybrid multi-criteria decision-making framework was applied to obtain the demand points’ weight and ranking in a real-life earthquake scenario. Direct shipment and lateral transshipment models were then presented and compared. The developed mathematical models are formulated as mixed-integer programming models, considering facility location, inventory prepositioning, road vulnerability and quantity of lateral transshipment.

Findings

The study found that the use of prioritization criteria and subcriteria, in conjunction with lateral transshipment and road vulnerability, resulted in a more equitable distribution of relief items by reducing the total average inflated distance traveled per relief item.

Research limitations/implications

To the best of the authors’ knowledge, this study is one of the first research on equity in humanitarian response through prioritization of demand points. It also bridges the gap between two areas that are typically treated separately: multi-criteria decision-making and humanitarian logistics.

Practical implications

This is the first scholarly work in Shiraz focused on the equitable distribution system by prioritization of demand points and assigning relief items to them after the occurrence of a medium-scale earthquake scenario considering lateral transshipment in the upper echelon.

Originality/value

The paper clarifies how to prioritize demand points to promote equity in humanitarian logistics when the authors have faced multiple factors (i.e. location of relief distribution centers, inventory level, distance, lateral transshipment and road vulnerability) simultaneously.

Abstract

Purpose

In daily life, some special systems are difficult to handle, such as indistinct systems (the reverse of explicit systems), history systems, future systems, infinite systems, etc. It is one of the more important topics of broad-spectrum philosophy to give these systems observo-controllable and -manipulatable forms from the angle of epistemology and methodology. The paper aims to discuss these issues.

Design/methodology/approach

The author conducted a broad-spectrum analysis of some typical mechanisms of general object systems and general cognition systems through a generalized quantification method and a dynamic structure method.

Findings

Through generalized quantification and dynamic structure methods, the author can draw some new conclusions about these special systems: for example, the indistinct system has certain relations and structures, but these relations and structures cannot be observo-controlled directly under certain conditions; further, the indistinct system and explicit system are interdependent, and therefore people can transform an indistinct system into an explicit one.

Originality/value

Through the study of special systems, the author may find a new perspective and research topic for broad-spectrum philosophy, which may provide a new concept and study frame for future analysis of these special systems.

Abstract

Purpose

Chiang Rai being an earthquake-prone city, it is essential to raise awareness about earthquake safety and readiness, especially amongst the elderly population who spend most of their time at home. The purpose of this paper is to evaluate the earthquake preparedness of elders in relation to knowledge, attitude and practice.

Design/methodology/approach

This was an analytic cross-sectional study. Research data were collected from 480 elders of 60 years old and above. The research instruments were questionnaires about knowledge, attitude and self-assessment of practices in earthquake situations. Data were analyzed by number, percentage and a χ2 test.

Findings

Of participants interviewed, 39.4 percent were aged between 60 and 66 years old. Overall, 94.0 percent of them had already experienced an earthquake, with 79.4 percent having experienced it in 2014. Participants had a good level of knowledge and attitude toward earthquake safety. Their practices toward earthquake readiness, however, were insufficient due to the lower practice scores (<12), especially found in the high seismic zone. The score level of knowledge, attitude and self-assessment of practice in earthquake situations showed that there is a difference in statistical significance (p<0.05).

Originality/value

This study focuses attention on the need to increase levels of preparedness. Safety instructions and earthquake drills should be promoted and supported in order to prepare elders for an earthquake in the study area. Research findings identified in this study will help to address the specific needs of the elderly when implementing an earthquake disaster risk reduction plan.

Abstract

In Turkey, the process of squatterisation can best be traced to the increase in its urban population from 24 percent in 1950 to 59 percent in 2000. In the periods up to the present, the prevention, improvement and renewal of squatter settlements were not achieved within the existing legal framework and planning structure; and their urban quality has been degraded.

The aim of this article is to discuss the upgrading of squatter settlements through a mitigation process considering the possibility of an earthquake in Istanbul. The target groups of this upgrading study are the squatter dwellers and their settlements.

In getting prepared for the predicted big Istanbul earthquake, the improvement of squatter housing is extremely important for the existing urban housing stock. With this aim, the undesirable consequences of a possible natural disaster in various squatter settlements in Istanbul were scrutinised. Also, earthquake-forecasting reports were analysed in conjunction with squatter maps to extract data for the purpose of upgrading squatter settlements through rehabilitation, reconstruction and reinforcement at the urban and architectural levels with amelioration of damage after an earthquake. In the article, a model is proposed which includes measures to transform squatter zones into healthy areas by means of simple reinforcement and contemporary solutions.

This article is based on a research project requested and sponsored by the Istanbul Metropolitan Municipality during 2003-2004.
