Abstract:

This study aims to group earthquake damage from its magnitude scale and visualize it on a geographical map. The magnitude of the earthquake was grouped using the K-means model. It is one of the most popular and effective clustering models in grouping data, such as earthquake data. The dataset used in this study is earthquake data for the last ten years on Lombok Island. The optimal number of clusters was used which is 2 in this case, based on the highest Silhouette score of 0.930. The highest Silhouette score shows the optimal number of clusters. The cluster on the geographical map shows most

Abstract:

Earthquakes are natural phenomena that occur when the Earth's tectonic plates move and release energy. Big Data's emergent epistemological and research paradigms, as well as data science, an increasingly integrated field of data research, are opening up new opportunities. Visualizing earthquake data is all about understanding earthquake characteristics such as size, location and depth. The result show that September was the quietest month in terms of earthquakes, and in this graph we can see the number of earthquakes for each month in 2022. The month of October is the one that has the highest

Abstract Disastrous earthquakes and hurricanes, in general, are not contemporaneous.

The greatest aftershock struck almost at the same time with Hurricane Henriette inducing panic among the inhabitants of La Paz, Baja California, peninsula. After the earthquake’s main event, the disaster preparedness professionals’ effort focused more on hurricane protocols than on the effects that the earthquake’s aftershocks could have been produced.

The average annual, monthly, and daily values of the solar-terrestrial variables, the number of earthquakes with intensities that fall within the specified boundaries are calculated.

Abstract Long-term seismicity in a certain region can be estimated from the number of felt earthquakes obtained from seismic intensity measurements or historical documents. To obtain a homogeneous estimate, continuous records with a uniform detection threshold are required. Seismic intensity data in Tokyo, which are measured by professional observers and archived by the Japan Meteorological Agency (JMA) since 1885, indicate that the mean annual number of felt earthquakes with intensities ≥1 and ≥2 on the JMA scale is 45 and 14, respectively.

In various parts of the globe, there have been several earthquakes of a modest size. Monitoring the change of the points over time is a key component of typical techniques for extracting dynamic responses. This technique was unable to completely extract all of the earthquake’s dynamic properties. The GNSS precise point positioning (PPP) may be a useful tool for obtaining values of the point’s displacement that are more exact up to millimeters, which can help to overcome these flaws and evaluate the seismic wave of such earthquakes. Ultimately, PPP is a crucial tool for getting the precise obse

For a number of reasons, discussed in this chapter, taking such measurements is not trivial. With this chapter, we want to outline why such measurements are important, what data sets are

<p>The number of aging bridges in Japan is increased. Especially, corrosion of the girder end structures is serious problem that reduces the load-carrying capacity. Against this background, there is a growing trend in research focused on predicting the load-carrying capacity of bridges using 3D FEM. In these analytical studies, many evaluations on vertical load were carried out, but few evaluations on lateral load, such as earthquakes. In this paper, the finite element model of the girder end structure with corrosion was created and pushover analysis was conducted. The results of the ana

<p>In this paper we present the workings of a new platform designated for assessment and management of a large number of bridges. The platform combines advanced inspection and testing techniques, digital twinning, and Structural Health Monitoring (SHM). The overall goal of the framework developed by Kinemetrics is to construct an SHM platform that will efficiently monitor the safety and reliability of bridge infrastructure in big cities. However, on a more general level, our aim is to increase public safety as well as to reduce life cycle costs of bridge maintenance. For this reason, thi

Abstract:

During earthquakes, structures move laterally and since usually a proper gap distance between structures is not provided so the structures can collide with each other. Building codes which are commonly used, do not offer any provisions for designing the structures for additional forces due to pounding and so structures are susceptible to damage subjected to pounding during strong seismic events. Therefore, in the current study, effect of pounding on a structure is studied considering different parameters including number of stories, total weight, story stiffness and floor alignment with adjace

Nowadays, the use of supercomputing for solving almost any task ranging from industrial to the ecological ones has been increasing. It should be noted that this requires lots of energy, which negatively affects the environment and is costly. However, in a number of cases it is possible to achieve high performance calculations without the use of supercomputers but instead by relying on special processors, focused on a particular class of tasks. While optimizing the computational pipeline for a particular mathematical model, the modern Field Programmable Gates Array (FPGA) platform provides an o

Earthquakes pose a significant threat to the population, causing harm to individuals and also impacting modern infrastructure. Prediction of earthquakes as a subfield of seismology aims to address questions and problems related to forecasting of earthquakes.

Abstract: Earthquakes are natural disasters that have led to the displacement of large number of people in different parts of the world. These geophysical events, often destructive in scale, lead to short- or long-term displacement from vulnerable areas. The aim of this research is to analyse the impact of earthquakes on the intensity and dynamics of human mobility in the Balkan region. For this purpose, data on internal displacement under the influence of earthquakes in the Balkan countries in the period 2008-2023 were analysed and processed.

Our results suggest that people in these countries pay around 44 percent more attention to earthquakes in Western countries, holding constant earthquake magnitude and number of casualties.

This report describes several advances in the cyclic failure assessment of silt soils with immediate and practical benefit to the geotechnical earthquake engineering profession. First, a database of cyclic loading test data is assembled, evaluated, and used to assess trends in the curvature of the CRR-N (cyclic resistance ratio - the number of equivalent cycles) relationship. This effort culminated in a plasticity index-dependent function which can be used to estimate the exponent b in the power law describing cyclic resistance, and may be used to estimate the cyclic resistance of silt soils a

The completion of this study allows for a comprehensive catalogue in NE BC from 2014 to 2020 by building upon our previous 2014-2016 and 2017-2018 catalogues. Th

Evaluating the seismic performance of concrete dams requires nonlinear dynamic analysis of two- or three-dimensional dam–water–foundation rock systems that include all the factors known to be significant in the earthquake response of dams. Such analyses are greatly complicated by interaction between the structure, the impounded reservoir and the deformable foundation rock that supports it, and the fact that the fluid and foundation domains extend to large distances.
