Oceanic intraplate earthquakes: Implications for local and regional intraplate stress
Journal of Geophysical Research: Solid Earth, 1980Focal mechanisms of intraplate earthquakes provide the only means at present by which to characterize the long‐wavelength tectonic stress field in oceanic lithosphere. Stress orientations inferred from focal mechanisms may not accurately reflect the state of stress in the epicentral area, however, or the measured stresses may be dominated by local ...

DISPLACEMENT MODELLING OF INTRAPLATE EARTHQUAKES
ISET Journal of Earthquake Technology, 2004This paper presents the case for a displacement-based approach for the seismic design and performance assessment of structures in intraplate regions. A newly established model for predicting seismic displacement demand is introduced. The presented material is based on outcomes from research which integrates expertise in the fields of engineering ...

Intraplate earthquakes in the Svalbard Archipelago
Journal of Geophysical Research: Solid Earth, 1979A small, seismically active region, designated the Heerland seismic zone, has been delineated in the Svalbard archipelago. Over 500 earthquakes in this region, of which nearly 50 were reliably located, were recorded during a 9‐week field season in 1977.

A Nonlinear Model for Intraplate Earthquake
2020Intraplate earthquakes are very hazardous disaster for human’s society. The features of earthquake-generating process are discussed in this paper by using a dynamic nonlinear model with Chinese Continental area as an example. The theoretical computation result of the model shows similarity to the real seismicity in Mainland China.

Intraplate earthquakes occur away from tectonic plate boundaries: their locations are difficult to predict, risking huge damage and loss of life. The 2001 Bhuj earthquake (featured in this book) was the largest intraplate earthquake for three decades and has provided unique insight into these events. This cutting-edge book brings together research from

Intraplate Earthquakes in Iceland
1989Only a small proportion of Icelandic earthquakes is not directly associated with the mid-Atlantic plate boundary that crosses the island. These intraplate earthquakes fall mainly into two classes. In the first class are earthquakes occurring west of the main rift zone through Iceland, within the tongue of lithosphere that is bounded by the two ...

Three-level Tectonic Model for Intraplate Earthquakes
Earth Science Frontiers, 2009Abstract Earthquake is a process concerning the long-term accumulation and abrupt release of energy in nature. On the basis of the analysis of the characteristics of intraplate earthquake, we present a three-level tectonic model for intraplate earthquake.

BUILDING DUCTILITY DEMAND: INTERPLATE VERSUS INTRAPLATE EARTHQUAKES
Earthquake Engineering & Structural Dynamics, 1996The inelastic seismic response behaviour for a range of simplified single-degree-of-freedom models has been analysed using 180 random phase angle synthetic accelerograms with different frequency contents and different durations and 105 real accelerograms collected from different regions worldwide.

Attenuation models inferred from intraplate earthquake recordings
Earthquake Engineering & Structural Dynamics, 1990AbstractStrong‐motion recordings at 87 sites from 56 different intraplate earthquakes from North America, Europe, China and Australia have been used through a two‐step regression analysis to develop new attenuation models for peak ground acceleration, and for pseudo‐relative velocity for frequencies of 0.25, 0.5, 1.0, 2.0, 5.0 and 10.0 Hz, all for 5 ...

On the nature of intraplate earthquakes
Journal of Seismology, 2016Continental intraplate regions are characterized by uniform stresses over thousands of kilometers. Local stresses, with wavelengths of tens to hundreds of kilometers can accumulate at inhomogeneities lying within these regional fields. A variety of geological structures, herein called local stress concentrators (LSCs), act as elastic inhomogeneities ...
