High-amplitude seismic waves from the Mw 7.0 Kumamoto earthquake of April 16, 2016, triggered another large earthquake 80 km to the NE roughly 30 s later. The source was located at shallow depths beneath the Yufuin geothermal field, Oita Prefecture, Japan, and the event magnitude was approximately 5.9. To date, this is one of the clearest known examples of a remotely triggered large earthquake....

This is the second of a two-part paper introducing a risk-based global coordination system in a distributed environment for collaborative design. Part I represents the basic concepts and a theoretical framework, and this paper describes a practical application in a National Science Foundation/George E. Brown, Jr Network for Earthquake Engineering Simulation. Core concepts, theoretical framework...

The Southern California Earthquake Center initiated a major largescale earthquake simulation called TeraShake. The simulations propagated seismic waves across a domain of 600x300x80 km at 200 meter resolution, some of the largest and most detailed earthquake simulations of the southern San Andreas fault. The output from a single simulation may be as large as 47 terabytes of data and 400,000 fil...

The primary goal of NEESgrid data/metadata effort is to work collaboratively with NEESgrid System Integrator team and the NEES community and to help define data requirements and needs for the George Brown Jr. Network for Earthquake Engineering Simulation instigated by the National Science Foundation. The NEESgrid promotes NEES as a distributed virtual laboratory for earthquake engineering resea...

Hybrid control system composed of a base isolation system and a magneto-rheological damper so-called smart base isolation is one of effective semi-active control system in controlling the seismic response of structures. In this paper, a design method is proposed for designing the smart base isolation system in order to achieve an effective performance under multiple earthquakes. The base mass, ...

Dynamic rupture process of earthquake fault and its near-field strong ground motions are simulated by time-space-decoupled, explicit finite element method with multi-transmitting formula (MTF) of artificial boundary in this paper. This decoupled, explicit method has advantage to easily incorporate into time-step simulation of dynamic rupture process on earthquake fault, as well as wave motions....

The recent studies show that the past researches may have significantly underestimated earthquake and tsunami hazard in the Makran Subduction Zone (MSZ) and this region is potentially capable of producing major earthquakes. In this study, the worst case possible earthquake scenarios of the MSZ are simulated using fully nonlinear boussinesq model to investigate tsunami hazards on the Jask Port, ...

Earthquake early warning (EEW) can reduce harm to people and infrastructure from earthquakes and tsunamis, but it has not been implemented in most high earthquake-risk regions because of prohibitive cost. Common consumer devices such as smartphones contain low-cost versions of the sensors used in EEW. Although less accurate than scientific-grade instruments, these sensors are globally ubiquitou...
