Seismic rate variations prior to the 2010 Maule, Chile MW 8.8 giant megathrust earthquake
(Nature, 2021)
The M-W 8.8 Maule earthquake is the largest well-recorded megathrust earthquake reported in South America. It is known to have had very few foreshocks due to its locking degree, and a strong aftershock activity. We analyze ...
Earthquake segmentation in northern Chile correlates with curved plate geometry
(Nature Publishing Group, 2019)
We performed an integrated analysis of the coseismic slip, afterslip and aftershock activity of the 2014 M w 8.1 Pisagua earthquake. This earthquake seems to be spatially located between two major historical earthquakes, ...
The effect of dynamic loading on the shear strength of pyroclastic Ash Deposits and implications for landslide hazard: The case of Pudahuel Ignimbrite, Chile
(Elsevier, 2016)
The co-seismic and post-seismic behaviour of pyroclastic ash deposits and its influence on slope stability remains as a challenging subject in engineering geology. Case studies in volcanic areas of the world suggest that ...
Preservation potential of tsunami deposits on arid siliciclastic coasts
(ElsevierNL, 2013-11)
Numerous post-tsunami surveys have been conducted in the last two decades, especially since the 2004 Indian Ocean tsunami. These studies have documented a variety of characteristic sedimentary and erosional features that ...
Rupture processes of the 2012 September 5 Mw 7.6 Nicoya, Costa Rica earthquake constrained by improved geodetic and seismological observations
(2015-08-17)
On 2012 September 5, the anticipated interplate thrust earthquake ruptured beneath the Nicoya peninsula in northwestern Costa Rica close to the Middle America trench, with a magnitude Mw 7.6. Extensive co-seismic observations ...
Gradients from GOCE reveal gravity changes before Pisagua Mw = 8.2 and Iquique Mw = 7.7 large megathrust earthquakes
(Elsevier, 2015-12)
Considerable improvements in the measurement of the Earth gravity field from GOCE satellite mission have provided global gravity field models with homogeneous coverage, high precision and good spatial resolution. In ...
Detection of pre-eruptive seismic velocity variations at an andesitic volcano using ambient noise correlation on 3-component stations: Ubinas volcano, Peru, 2014
(Elsevier B.V.NL, 2019-09)
Volcano monitoring and eruption forecasting are based on the observation and joined interpretation of several precursory phenomena. It is thus important to detect new types of precursor and to study their relationship with ...
Reloca Slide: an similar to 24km(3) submarine mass-wasting event in response to over-steepening and failure of the central Chilean continental slope
(Wiley-Blackwell, 2016)
Reloca Slide is the relict of an similar to 24-km(3) submarine slope collapse at the base of the convergent continental margin of central Chile. Bathymetric and seismic data show that directly to the north and south of the ...
