Geochronology, Geochemistry and Sr-Nd-Pb-Hf Isotopes of No. I Complex from the Shitoukengde Ni–Cu Sulfide Deposit in the Eastern Kunlun Orogen, Western China: Implications for the Magmatic Source, Geodynamic Setting and Genesis
Sr-Nd-Pb-Hf isotopes crustal contamination oceanic slab break-off post-collisional extension Shitoukengde Ni-Cu deposit Eastern Kunlun Orogen
2018/4/10
The Shitoukengde Ni-Cu deposit, located in the Eastern Kunlun Orogen, comprises three mafic–ultramafic complexes, with the No. I complex hosting six Ni-Cu orebodies found recently. The deposit is host...
Bayesian seismic multi-scale inversion in complex Laplace mixed domains
Low-frequency Complex mixed-domain Laplace inversion Bayesian estimation Multi-scale inversion
2018/4/2
Seismic inversion performed in the time or frequency domain cannot always recover the long-wavelength background of subsurface parameters due to the lack of low-frequency seismic records. Since the lo...
Earth modeling and estimation of the local seismic ground motion due to site geology in complex volcanoclastic areas
dynamic amplification factor seismic tomography pyroclastic rocks finite element method
2015/9/25
Volcanic areas often show complex behaviour as far as seismic waves propagation and seismic motion at surface are concerned. In fact, the finite lateral extent of surface layers such as lava flows, bl...
Lichenometry dating of coseismic changes to a New Zealand landslide complex

2015/9/16
Lichenometry is a surface-exposure-dating procedure that complements traditional trench-and-date stratigraphic studies of earthquakes. Lichens on the surficial blocks of a slump in the Seaward Kaikour...
In 2002, the National Institute for Earth Physics started the development of its own real-time digital seismic network. This now consists of 86 seismic stations, of which 32 are broad-band sensors, 52...
Maskevarri Ráhppát in Finnmark, northern Norway – is it an earthquake-induced landform complex?
Sami rahppat coarse boulders terrain new tectonic fault and earthquake
2015/1/6
The Sami word ráhppát means rough bouldery/stony terrain with sharp-relief topography in Finnmark, northern Norway. Ráhppát is a common name in the region of the Younger Dryas landforms, yet the origi...
Modelling complex geological circular data with the projected normal distribution and mixtures of von Mises distributions
Circulation data earth science statistical description structural geology circulation data set
2015/1/6
Circular data are commonly encountered in the earth sciences and statistical descriptions and inferences about such data are necessary in structural geology. In this paper we compare two statistical d...

High resolution reflection seismic profiling Tjellefonna fault More-Trondelag Fault Complex Norway
2015/1/4
The Møre-Trøndelag Fault Complex (MTFC) is one of the most prominent fault zones of Norway, both onshore and offshore. In spite of its importance, very little is known of the deeper structur...
Geophysical characterisation of two segments of the Møre-Trøndelag Fault Complex, Mid Norway
Geophysical characterisation two segments of the More-Trondelag Fault Complex Mid Norway
2014/12/31
The Møre-Trøndelag Fault Complex (MTFC) has controlled the tectonic evolution of Mid Norway and its shelf for the past 400 Myr through repeated reactivations during Palaeozoic, Mesozoic and ...

We present results of thorough benchmarking of
an arbitrary high-order derivative discontinuous Galerkin
(ADER-DG) method on unstructured meshes for advanced
earthquake dynamic rupture problems.

Complex rupture during the 12 January 2010 Haiti earthquake
2014/4/9
Initially, the devastating Mw 7.0, 12 January 2010 Haiti earthquake seemed to involve straightforward accommodation of oblique relative motion between the Caribbean and North American plates along the...
Flux-gradient relationship for turbulent dispersion over complex terrain
Flux-gradient relationship turbulent dispersion complex terrain
2009/11/16
The transfer of a passive tracer in inhomogeneous turbulent flow is investigated. Starting from Lumley's constitutive equation, we derived an expression for the ratio between the effective eddy diffus...
Modelling the outer radiation belt as a complex system in a self-organised critical state
outer radiation belt complex system self-organised critical state
2009/11/11
The dynamic behaviour of the outer electron radiation belt makes this area of geo-space a candidate for the concept of self-organized criticality. It is shown here that frequency distributions of meas...
We invoke a metric to quantify the correlation between any two earthquakes. This provides a simple and straightforward alternative to using space-time windows to detect aftershock sequences and obviat...
