Due to the lack of proper preparedness in the country against natural disasters, even an earthquake of moderate magnitude can cause extensive damage. This necessitates seismic zonation. Seismic zonation is a process in which a large region is demarcated into small zones based on the levels of...

Turkey has been divided into eight different seismic regions taking into consideration the tectonic environments and epicenters of the earthquakes to examine relationships of the modal values (a/b), the expected maximum magnitudes (M <Subscript>max</Subscript>) and the maximum intensities (I <Subscript>max</Subscript>). For this purpose,...</subscript></subscript>

Indian peninsular shield, which was once considered to be seismically stable, is experiencing many earthquakes recently. As part of the national level microzonation programme, Department of Science and Technology, Govt. of India has initiated microzonation of greater Bangalore region. The...

An innovative approach to seismic hazard assessment is illustrated that, based on the available knowledge of the physical properties of the Earth structure and of seismic sources, on geodetic observations, as well as on the geophysical forward modeling, allows for a time-dependent definition of...

To estimate seismic hazard, the basic law of seismicity, the Gutenberg–Richter recurrence relation, is applied in a modified form involving a spatial term: <InlineEquation ID="IEq1"> <EquationSource Format="TEX">$$\log N\left( {M,\;L} \right)=A - B\left( {M - 5} \right) + C\log L$$</EquationSource> <EquationSource Format="MATHML"> <math xmlns:xlink="http://www.w3.org/1999/xlink"> <mrow> <mo>log</mo> <mi>N</mi> <mfenced close=")" open="(" separators=""> <mrow> <mi>M</mi> <mo>,</mo> <mspace width="0.277778em"/> <mi>L</mi> </mrow> </mfenced> <mo>=</mo> <mi>A</mi> <mo>-</mo> <mi>B</mi> <mfenced close=")" open="(" separators=""> <mrow> <mi>M</mi> <mo>-</mo> <mn>5</mn> </mrow> </mfenced> <mo>+</mo> <mi>C</mi> <mo>log</mo> <mi>L</mi> </mrow> </math> </EquationSource> </InlineEquation>, where N(M,L)...</equationsource></equationsource></inlineequation>

This study presents the future seismic hazard map of Coimbatore city, India, by considering rupture phenomenon. Seismotectonic map for Coimbatore has been generated using past earthquakes and seismic sources within 300 km radius around the city. The region experienced a largest earthquake of...

Attenuation relationships are commonly used for engineering studies to estimate the peak ground acceleration values. This paper presents the role of attenuation relationship in defining the seismic hazard in an area. It is seen that the seismic hazard in an area, which is calculated using...

The assessment of geological hazard is a topic with significant interest for the Balkans. During the last decade of twentieth century, most of the countries in the region have embarked on the road of a hasty transitory period from totalitarian regimes to democracy. Development of free market...

In this paper, we present a probabilistic seismic hazard analysis (PSHA) for mainland Spain that takes into account recent new results in seismicity, seismic zoning, and strong ground attenuation not considered in the latest PSHA of the Spanish Building Code. Those new input data have been...

The National Capital Region (NCR) of India is exposed to high seismic hazard and risk due to a great earthquake in the central seismic gap of Himalaya and/or due to moderate-size earthquake within NCR. The high population density, rapid growth of infrastructure, and old engineering structures in...
