Earthquake [earthquake warning systems]

IEEE Spectrum, 2005
Accurate earthquake warnings are, at last, within reach. Instead of coming from the mechanical phenomena that have been the focus of decades of study, however, they will come from electromagnetic phenomena. And, remarkably, these predictions will come from signals gathered not only at the earth's surface but also in the ionosphere. It has been observed

Earthquake monitoring and warning system

2015 International Conference on Advances in Electrical Engineering (ICAEE), 2015
The project aims at designing an earthquake monitoring and warning system that is capable of detecting earthquakes as well as warning people to take necessary precautions. This system will not only attempt to save human lives, but will also store the data for later use by professionals working at this sector.

Cheap earthquake warning systems [News]

IEEE Spectrum, 2015
While predicting earthquakes remains a dream, scientists have developed early-warning systems that give people precious seconds to run out of buildings or take cover. Such systems are in place in Japan and Mexico. The U.S. Geological Survey (USGS) is testing a system that gave a 5- to 10-second warning when a temblor hit California’s Napa Valley in ...

Potential of Earthquake Early Warning Systems

Natural Hazards, 2001
Despite 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.

DESTRUCTIVE EARTHQUAKES AND TSUNAMI WARNING SYSTEM

Terra Nova, 1991
AbstractThe Portuguese coast has been affected several times in the past by strong earthquakes that generated tsunamis severely damaging the city of Lisbon.The most significant event known was the Lisbon earthquake of 1 November 1755. It is generally assumed that the location of this event was the Gorringe Bank region in the North Atlantic. This ridge,

A prototype earthquake warning system for strike-slip earthquakes

pure and applied geophysics, 1990
A prototype expert system has been developed to provide rapid warning of earthquakes while they are occurring. Warning times of up to 100 seconds will be possible. In the complete system, several accelerometers are distributed at intervals within a few kilometers of a known fault; data are telemetered to a central computer which implements the expert ...

An emergency Earthquake warning system for land mobile vehicles using the earthquake early warning

2008 IEEE International Conference on Vehicular Electronics and Safety, 2008
This paper describes a study of an emergency earthquake warning system for land mobile vehicles using the Earthquake early warning in Japan, First, estimation accuracy of seismic wave is evaluated at a local area, when using both the position information and the soil information database in addition to the Earthquake early warning, and it is shown that

A MacBook based earthquake early warning system

2016 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS), 2016
We demonstrate an early stage of our prototypical development of an earthquake early warning system based on Apple's MacBook computers. This system, called MacSeisApp, utilizes the Sudden Motion Sensors in MacBooks to detect seismic activities. It is inspired by an existing application called SeisMac, which turns a MacBook computer into a seismograph ...

TremorFlash: Earthquake warning and follow-up system

Nepalese Journal of Engineering, 2005
This paper describes the design approach towards the construction of an earthquake warning and follow-up system, TremorFlash. The approach consists in integration of software engineering and hardware organization. On software front, we utilize Unified Modeling Language specifications and tools of object-oriented analysis and design.

Modeling warning times for the Israel’s earthquake early warning system

Journal of Seismology, 2014
In June 2012, the Israeli government approved the offer of the creation of an earthquake early warning system (EEWS) that would provide timely alarms for schools and colleges in Israel. A network configuration was chosen, consisting of a staggered line of ∼100 stations along the main regional faults: the Dead Sea fault and the Carmel fault, and an ...
