Earthquake is the shaking of the earth's surface due to the shift in the earth's plates. This disaster often happens in Indonesia due to the location of the country on the three largest plates in the world and nine small others which meet at an area to form a complex plate arrangement. An earthquake has several impacts which depend on the magnitude and depth. This research was, therefore, conducted to classify earthquake data in Indonesia based on the magnitudes and depths using one of the data mining techniques which is known as clustering through the application of k-medoids and k-means algorithms. However, k-medoids group data into clusters with medoid as the centroid and it involves using clustering large application (CLARA) algorithm while k-means divide data into k clusters where each object belongs to the cluster with the closest average. The results showed the best clustering for earthquake data in Indonesia based on magnitude and depth is the CLARA algorithm and five clusters were found to have total members of 2231, 1359, 914, 2392, and 199 objects for cluster 1 to cluster 5 respectively.

This paper discusses what we already do and what extra should be done lo reduce earthquake risk in New Zealand. Some of the needed actions have been learned from the consequences, good as well as bad, of earthquakes that have occurred both in New Zealand and in other parts of the world. A list of 26 weaknesses are identified in New Zealand's systems of earthquake risk reduction. Remedial actions to overcome these weaknesses in a balanced way involve at least nine parties. Fifteen of the weaknesses have five or more parties who could or should take some remedial action over them. Engineers have technical actions to address 20 of the weaknesses, while earthquake-related professions have an advocacy role to play in all of them. The potential exists for reducing earthquake losses by about an order of magnitude, i.e. worth billions of dollars and thousands of casualties in future earthquakes.

In many countries around the world, building and bridge structures with close proximity to known earthquake faults have been constructed with little consideration to the effects of strong ground shaking. This paper discusses some of the infrastructure and systems required in a country to prevent structural collapse, and hence major loss, in a major earthquake. The modus operandi of one group which seeks to reduce earthquake loss in these countries, the World Seismic Safety Initiative, is described. Finally, a case study is carried out on Myanmar where extraordinary strides that have been made toward earthquake risk reduction in a relatively short period of time.

Abstract In the science of seismology, issues such as the study of tectonic seismic maps and the identification of the behavioural pattern of pre-earthquakes and aftershocks are among the cases that have been proposed as the basis of applied geological studies in recent decades. Accordingly, numerous studies and researches in this field have been carried out in different regions of the world. However, the results of these studies so far have not been able to meet the needs of this field in a practical and practical way, and in this regard, there is a need to provide practical approaches in this field. In order to realize this approach, there is a need for specialized research and case studies in this field in order to be able to present studies on earthquake risk reduction in an institutionalized and practical way by identifying practical patterns. In this study, the basis of the case study, considering the special characteristics of Tasuj earthquake as one of the important earthquakes according to the basic patterns that can be provided in this field for this earthquake has been considered. Also geodetic analysis of Tasuj fault and the other faults studied for estimation of accuracy this analysis for prediction of earthquake. The results of this study indicate that the fault causing the Tasuj earthquake, contrary to what is presented in the fault map of the region and previous reports and articles, is of the strike-slip type, which should be corrected. Also, the analysis of the behavioural pattern of geodetic data, foreshocks and aftershocks as a precursor shows that these patterns can be used in predicting major earthquakes and large aftershocks. To predict the time of large aftershocks in this study, three phases have been used, which are based on changes in depth to magnitude, changes in seismic quiescence to magnitude and depth changes.

Abstract. The Ismetpasa segment of the North Anatolian Fault is one of the rare places in the world where aseismic creep event has been observed. This segment was ruptured during both the 1944, Mw=7.2, Gerede and 1951, Mw=6.9, Kursunlu earthquakes. After these earthquakes, the segment has not experienced a major earthquake anymore. Starting from 1957, many studies using different technologies have been carried out to determine the creep rate of the segment. All these studies until 2002 revealed that the creep movement of the segment slowed down. The new observation campaign of the Ismetpasa geodetic network shows that the Ismetpasa segment has ceased the slowing trend and started to gain speed. This might be interpreted as an increasing earthquake risk for this segment.

We develop a global database of building inventories using taxonomy of global building types for use in near-real-time post-earthquake loss estimation and pre-earthquake risk analysis, for the U.S. Geological Survey's Prompt Assessment of Global Earthquakes for Response (PAGER) program. The database is available for public use, subject to peer review, scrutiny, and open enhancement. On a country-by-country level, it contains estimates of the distribution of building types categorized by material, lateral force resisting system, and occupancy type (residential or nonresidential, urban or rural). The database draws on and harmonizes numerous sources: (1) UN statistics, (2) UN Habitat's demographic and health survey (DHS) database, (3) national housing censuses, (4) the World Housing Encyclopedia and (5) other literature.

Pragmatist Philosophy

AbstractA pragmatist philosophy of psychological science offers to the direct replication debate concrete recommendations and novel benefits that are not discussed in Zwaan et al. This philosophy guides our work as field experimentalists interested in behavioral measurement. Furthermore, all psychologists can relate to its ultimate aim set out by William James: to study mental processes that provide explanations for why people behave as they do in the world.

Abstract Culture shapes our basic sensory experience of the world. This is particularly striking in the study of religion and psychosis, where we and others have shown that cultural context determines both the structure and content of hallucination-like events. The cultural shaping of hallucinations may provide a rich case-study for linking cultural learning with emerging prediction-based models of perception.

Abstract Hoerl & McCormack argue that animals cannot represent past situations and subsume animals’ memory-like representations within a model of the world. I suggest calling these memory-like representations as what they are without beating around the bush. I refer to them as event memories and explain how they are different from episodic memory and how they can guide action in animal cognition.

AbstractFe XIV 530.3 nm coronal emission line observations have been used for the estimation of the green solar corona rotation. A homogeneous data set, created from measurements of the world-wide coronagraphic network, has been examined with a help of correlation analysis to reveal the averaged synodic rotation period as a function of latitude and time over the epoch from 1947 to 1991.The values of the synodic rotation period obtained for this epoch for the whole range of latitudes and a latitude band ±30° are 27.52±0.12 days and 26.95±0.21 days, resp. A differential rotation of green solar corona, with local period maxima around ±60° and minimum of the rotation period at the equator, was confirmed. No clear cyclic variation of the rotation has been found for examinated epoch but some monotonic trends for some time intervals are presented.A detailed investigation of the original data and their correlation functions has shown that an existence of sufficiently reliable tracers is not evident for the whole set of examinated data. This should be taken into account in future more precise estimations of the green corona rotation period.
