...Alix Becerra; Esteban Sáez; Luis Podestá; Felipe Leyton In this study, we present comparisons between the local soil conditions and the observed damage for the 1 April 2014 Iquique earthquake. Four cases in which site effects may have played a predominant role are analyzed: (1) the ZOFRI area...

...Marcella G. Cilia; Walter D. Mooney; Andrew Robinson ABSTRACT We conducted a regional seismic intensity survey in northern Chile following the 1 April 2014 M 8.2 Iquique earthquake to document the level of damage caused by the earthquake and tsunami. We observed very limited damage at the 204 sites...

...Arthur Frankel ABSTRACT Strong‐motion recordings of the 2014 M w 8.2 Iquique and 2015 M w 8.3 Illapel, Chile, earthquakes were analyzed to determine rupture propagation and the location, timing, and strength of subevents that produce most of the high‐frequency (≥1 Hz) ground motions. A moving...

... the days before or after 1 April 2014. Numbers list the number of events shown in the subpanel between the day listed and the day of the next subpanel. Pink square marks epicenter of the Iquique earthquake. Other features include black line (trench), brown line (coast), and blue and red colors of text...

... in the 1960 Mw 9.5 Valdivia earthquake ( Duke and Leeds, 1963 ). Recently, four large earthquakes occurred in Chile: the 2010 Mw 8.8 Maule, 2014 Mw 8.2 Iquique, 2015 Mw 8.3 Illapel, and 2016 Mw 7.6 Melinka, where liquefaction caused multiple damages generating millions in losses (in US dollars). When used...

... a temporal evolution of their frequency content in the earthquake sequence associated with the 2014 Iquique M w 8.1 megathrust earthquake. Surprisingly, the change does not occur with the mainshock but is associated with an 8 month slow slip preceding the megathrust. 14 February 2017 ©...

... that allows us to replay past or synthetic earthquakes to help identify problems with both the network architecture and the algorithms. Here, we report on the performance of G‐FAST during three large megathrust earthquakes in Chile: the 2010 M w 8.8 Maule, the 2014 M w 8.2 Iquique, and the 2015 M w 8.3...

... waves. We present the first validation of semistochastic broadband P waves, comparing our waveforms against observations of the 2014 M w 8.1 Iquique, Chile, earthquake in the time domain and across frequencies of interest. We then consider the P waves in greater detail, using a set of synthetic...

... used in this study are marked in blue. Red circles indicate the hypocenters of the 2014 M w  8.1 Iquique mainshock and the M w  7.6 aftershock. The network was in large part functional, when the M w  8.1 Iquique megathrust earthquake partially broke the seismic gap on 1...

... accelerograms are compared with the observed data recorded on rock by the Integrated Plate boundary Observatory Chile ( IPOC ) network during the 2007 Tocopilla and 2014 Iquique earthquakes. The use of P , SV , and SH waves in the stochastic simulation allowed us to generate three‐component synthetic records...
