...Nathan Campbell; Estella Atekwana; Adam J. Mathews; Ahmed Ismail Abstract More than 5 billion people have access to mobile phones globally. These devices, many of which are smartphones with multiple integrated sensors (e.g., global positioning system receiver, camera, etc.), provide a myriad...

...Rémy Bossu; Maud Laurin; Gilles Mazet-Roux; Frédéric Roussel; Robert Steed Abstract This study investigates how people affected by the 2015 Ghorka earthquake sequence in Nepal have adopted and used the LastQuake smartphone application and associated Twitter robot, which offer rapid earthquake...

...Qingkai Kong; Richard M. Allen; Steve Allen; Theron Bair; Akie Meja; Sarina Patel; Jennifer Strauss; Stephen Thompson Abstract MyShake is a free citizen science smartphone app that provides a range of features related to earthquakes. Features available globally include rapid postearthquake...

...Qingkai Kong; Richard M. Allen; Monica D. Kohler; Thomas H. Heaton; Julian Bunn ABSTRACT This article presents the results of a shaker test of the Millikan Library in Pasadena, California, using sensors inside smartphones to demonstrate their potential usage as a way to monitor health states...

... intensity data or smartphone data, could prove essential. The predictive power of this nontraditional data for free‐field ground motion needs to be tested before these data are used. In this work, we present a new database of over 1600 ground‐shaking waveforms collected between 2019 and 2023 by the MyShake...

...Asaf Inbal; Qingkai Kong; William Savran; Richard M. Allen ABSTRACT MyShake is a growing smartphone‐based network for seismological research applications. We study how dense array analysis of the seismic wavefield recorded by smartphones may enhance microearthquake monitoring in urban environments...

...Qingkai Kong; Asaf Inbal; Richard M. Allen; Qin Lv; Arno Puder ABSTRACT This article gives an overview of machine learning (ML) applications in MyShake—a crowdsourcing global smartphone seismic network. Algorithms from classification, regression, and clustering are used in the MyShake system...

...Francesco Finazzi; István Bondár; Rémy Bossu; Robert Steed Abstract Earthquake early warning systems based on smartphone networks are emerging as complementary systems to the more expensive systems based on scientific‐grade instruments. Hence, there is a need to better understand their detection...

...Qingkai Kong; Sarina Patel; Asaf Inbal; Richard M. Allen Abstract MyShake harnesses private and personal smartphones to build a global seismic network. It uses the accelerometers embedded in all smartphones to record ground motions induced by earthquakes, returning recorded waveforms to a central...

... models, which involves the use of photo orientation information recorded by smartphones. Photos captured with smartphones are used to: (1) build test models for evaluating the accuracy of the method, and (2) build smartphone-derived models of outcrops, used to reference higher-resolution models...
