Performance-based earthquake early warning
Soil Dynamics and Earthquake Engineering, 2011Significant investments are undergoing internationally to develop earthquake early warning (EEW) systems. So far, reasonably, the most of the research in this field was lead by seismologists as the issues to determine essential feasibility of EEW were mainly related to the earthquake source. Many of them have been brilliantly solved, and the principles

Crowdsourcing earthquake early warnings
Science, 2016Seismology The rapid distribution of earthquake warnings can reduce resulting loss of life and injury. Most earthquake early warning systems are based on data from specially designed seismic and geodetic networks. Kong et al. developed a system that gathers and distributes earthquake data from smartphone sensors, substantially improving our ability to ...

An Open‐Source Earthquake Early Warning Display
Seismological Research Letters, 2016We present the earthquake early warning display (EEWD), an effort to build a free and open‐source software to display earthquake early warning (EEW) information. The EEWD design and development builds on the experience of the Swiss Seismological Service at ETH Zurich in running the ShakeAlert UserDisplay developed by Caltech in California.

Automated decision procedure for earthquake early warning
Engineering Structures, 2007Early warning systems represent an effective tool for disseminating timely information about potentially catastrophic hazards to the public, emergency managers, and operators and users of transportation systems, industrial facilities, public buildings including schools and government offices, and private residences.

IEEE Spectrum, 2007
This paper presents NASA scientist Friedemann Freund's experiments on why radio frequency phenomena precede some earthquakes. He demonstrated in the laboratory how the earth's crust can act as a gigantic battery to drive a geological radio circuit that extends more than 30 kilometers below the ground.

Outcome-Based Earthquake early Warning
Advanced Materials Research, 2012Earthquake early warning (EEW) has been popular since 2007, but Wenchuan Earthquake occurred in China in 2008, Haiti Earthquake, Chile Earthquake and Yushu Earthquake occurred respectively in Haiti, Chile and China in 2010, and East Japan Earthquake occurred in Japan in 2011.

Potential of Earthquake Early Warning Systems
Natural Hazards, 2001Despite their short warning times (seconds to tens of seconds)earthquake early warning systems can become useful tools in riskmitigation provided their design is robust and utilizes theregional tectonics. Bucharest can serve as a good example forsuch a system with a warning time of 25 seconds.

Earthquake Early Warning System in Japan
2003Japan is situated in one of the most active areas in the world, where the Pacific and Philippine Sea Plates are subducting the Eurasian Plate and where stress and strain of the crust are accumulated (Fig. 1). This results in a lot of earthquakes, tsunamis and volcanic eruptions.
