We investigate the generation, propagation, and probabilistic hazard of tsunami spawned by oceanic asteroid impacts. The process first links the depth and diameter of parabolic impact cavities to asteroid density, radius, and impact velocity by means of elementary energy arguments and crater scaling rules. Then, linear tsunami theory illustrates how these transient cavities evolve into vertical...

This paper study the recent seismicity in Earthquake hazard zones in India. A large historical earthquake event catalog to cover the period of 1900-2018, the parameters date, time, latitude, longitude, depth and magnitude has been used to calculating frequency-magnitude distribution (b-value) of seismic hazard zones in India. To convert different magnitude scales into a single moment magnitude ...

Determining the likelihood of a disaster is a key component of any comprehensive hazard assessment. This is particularly true for tsunamis, even though most tsunami hazard assessments have in the past relied on scenario or deterministic type models. We discuss probabilistic tsunami hazard analysis (PTHA) from the standpoint of integrating computational methods with empirical analysis of past ts...

To avoid over-reliance on the identification of building damage states post-earthquake in seismic risk assessment process, an ontology-based holistic and probabilistic framework is proposed here for prediction buildings with various purposes different states. Based vulnerability analysis, probabilities are first obtained by considering on-site hazard. Taking economic losses casualties as indica...

A gas distribution system comprises two main categories of components: (i) a number of point-like critical facilities (reduction stations and groups); and (ii) pipelines constituting the distribution network. The causes of earthquake damage to components of gas systems include permanent ground deformation (PGD) hazard produced by fault displacements, landslides, liquefaction of sandy soils, as ...

The goals of seismic impact assessment can be achieved by seismic monitoring systems and seismic impact simulator. Seismic monitoring system, for the purpose of hazard analysis, local site effects analysis, vulnerability analysis, and estimation of loss, is one application of SHM in earthquake engineering. A prototype, conceptual seismic impact simulator integrating SHM, FEM, GIS, and Virtual R...

Probabilistic Hazard Assessment (PHA) provides an appropriate methodology for assessing space weather hazards and their impact on technology. PHA is widely used in geosciences to determine the probability of exceedance critical thresholds, caused by one or more hazard sources. has proved useful with limited historical data estimate likelihood specific impacts. also driven development empirical ...
