At 12:51pm local time on 22 February 2011, a Mw 6.2 aftershock of the September 4, 2010, Darfield Earthquake shook the city of Christchurch, New Zealand. The aftershock occurred on an unmapped fault less than 8 km from the city center resulting in the collapse ...

Following the magnitude 7.1 Greendale earthquake on 4 September, 2010 and the magnitude 6.3 Lyttelton aftershock on 22 February, 2011 (which caused severe damage to the Christchurch CBD, the Eastern and Southern suburbs, the Port Hills and Lyttelton), the ...

On 4 September 2010, a surface rupturing earthquake (Mw 7.1) struck the Canterbury Plains region in New Zealand's South Island. The Canterbury Plains is a region of relatively low seismicity, and the structure that ruptured was a previously unmapped fault. ...

In 2004, the GeoNet project operated by GNS Science implemented an internet-based questionnaire. Its aim was to provide an automatic intensity assignment in New Zealand’s Modified Mercalli (MM) intensity scale based on answers to a set of standardized questions. ...

Aftershocks following an earthquake can be damaging to the built environment, as observed in New Zealand during 2010 and 2011. In this paper, the aftershock sequence is discussed and a soil-foundation-structure numerical model is introduced. The numerical ...

A total of 15 persons has been part of this 5 days field investigation in order to support the Spanish IGNintervention on the field after the Lorca earthquake. X. Goula, Leader of the Seismic Group of theInstitut of Geology of Catalunya was the coordinator ...

<p>Numerous source models for the mainshock have been inverted from seismic, geodetic, and tsunami observations. In this study is shown that, among six tested source models, there is a mean 47% gain in positively-stressed aftershock mechanisms over that for ...

<p>In this stydy have been used observations from Felzer and Brodsky (2006) of the variation of linear aftershock densities (i.e., aftershocks per unit length) with the magnitude of and distance from the main shock fault to derive constraints on how the probability ...

In this study is presented a catalogue of Izmit aftershock hypocenters that was deduced froma network covering the entire 140 km long rupture of the mainshock

To understand the reason why the co-seismic slip and tsunami amplitudes were so high in this region, was performed the "Sumatra Aftershocks" cruise (R/V Marion Dufresne, Jakarta, July 15 - Colombo, August 9, 2005) in order to establish the geodynamical context ...
