We introduce here the Earthquake Network project which implements a world-wide smartphone-based sensor network for the detection of earthquakes. Thanks to the accelerometric sensor, smartphones possibly detect the waves of a quake and report the event to a cloud computing infrastructure. In this work, we propose a solution to the detection problem based on statistical modelling the arrival time...

Editor’s note: The following is the text of the SSA Presidential Address presented at the Annual Luncheon of the Seismological Society of America (SSA) Annual Meeting on 30 April 2014. The Seismological Society of America (SSA) has always been dedicated to understanding and reducing the earthquake threat. The Society was founded in 1906 “for the acquisition and diffusion of knowledge concerning...

To further study the global seismic behaviour and post-earthquake reparability of RC building frames with proposed self-centring columns low-bond high-strength reinforcements (LBHSRs), incremental dynamic analysis (IDA) five-floor ten-floor frame archetypes under excitation by twenty ground motions (GMs) was performed. First, pushover results indicated that use LBHSR could substantially improve...

We investigated the source mechanism of the 1975 Kalapana, Hawaii, earthquake (Ms= 7.2) by modeling the tsunamis observed at three tide-gauge stations, Hilo, Kahului, and Honolulu. We computed synthetic tsunamis for various fault models. The arrival times and the amplitudes of the synthetic tsunamis computed for Ando's fault model (fault length= 40 km, fault width= 20 km, strike= N70°E, dip= 20...
