[1] The 25 October 2010 Mentawai, Indonesia earthquake (Mw 7.8) ruptured the shallow portion of the subduction zone seaward of the Mentawai islands, off‐shore of Sumatra, generating 3 to 9 m tsunami run‐up along southwestern coasts of the Pagai Islands that took at least 431 lives. Analyses of teleseismic P, SH and Rayleigh waves for finite‐fault source rupture characteristics indicate ∼90 s ru...

introduction natural hazards as recurring phenomenon have always existed in human life and will in the future, too. nowadays natural hazards occur throughout the world, but their impacts have been increasing and are generally much greater in developing countries than in developed ones. earthquake is a kind of natural hazard that has the most damages for humankind. earthquakes pose inevitable ri...

An automated, real-time, multiple sensor data source relying and globally applicable earthquake loss model and visualiser is desirable for post-event earthquake analysis. To achieve this there is a need to support rapid data ingestion, loss estimation and integration of data from multiple data sources and rapid visualisation at multiple geographic levels. In this paper, the design and developme...

The World Bank has reported Taiwan as the most vulnerable country in terms of the percentage of exposed areas and multiplicity disaster. During the past decade, a number of natural disasters have occurred in Taiwan, especially two critical ones, i.e. Chi-Chi earthquake and Typhoon Morakot. In the first event, the earthquake was with a magnitude of 7.3 on the Richter scale and caused seriously d...

Within the insurance industry, catastrophe modelling is a process for assessing and quantifying the impact of natural and man-made hazards on insured assets. This will involve replicating, using a computer model, the action of the hazard (earthquake, hurricane, flood), the vulnerability of the asset which is exposed to the hazard (e.g. a building, an oil-rig) and the financial mechanism of the ...

The goal of this paper is to derive a hazard map for earthquake occurrences in Pakistan from a catalogue that contains spatial coordinates of shallow earthquakes of magnitude 4.5 or larger aggregated over calendar years. We test relative temporal stationarity by the KPSS statistic and use the inhomogeneous J -function to test for inter-point interactions. We then formulate a cluster model, and ...

The probability of extreme events such as an earthquake, fire or blast occurring during the lifetime a structure is relatively low but these can cause serious damage to well human life. Due significant consequences for occupant and structural safety, accurate analysis response structures exposed required their design. Some may occur consequence another hazard, example, due failure electrical sy...

[1] Earthquake Early Warning (EEW) algorithms estimate the magnitude of an underway rupture from the first few seconds of the P-wave to allow hazard assessment and mitigation before the S-wave arrival. Many large subductionzone earthquakes initiate 50–150 km offshore, potentially allowing seafloor instruments sufficient time to identify large ruptures before the S-waves reach land. We tested an...

Continental intraplate seismicity seems often episodic, clustered, and migrating. The observed seismicity shows both spatial clustering in seismic zones and scattering across large plate interiors, temporal clustering followed by long periods of quiescence, and migration of seismicity from one seismic zone to another. Here, we explore the complex spatiotemporal patterns of intraplate seismicity...
