Learn to Detect: Improving the Accuracy of Earthquake Detection

IEEE Transactions on Geoscience and Remote Sensing, 2019
Earthquake early warning system uses high-speed computer network to transmit earthquake information to population center ahead of the arrival of destructive earthquake waves. This short (10 s of seconds) lead time will allow emergency responses such as turning off gas pipeline valves to be activated to mitigate potential disaster and casualties ...

Probability of Detecting an Earthquake

Bulletin of the Seismological Society of America, 2008
We present a new method for estimating earthquake detection proba- bilities that avoids assumptions about earthquake occurrence, for example, the event-size distribution, and uses only empirical data: phase data, station infor- mation, and network-specific attenuation relations.

Smartphone-based networks for earthquake detection

2015 15th International Conference on Innovations for Community Services (I4CS), 2015
To enhance current earthquake early warning (EEW) systems, emerging technologies, including social and mobile computing, have been the focus of much attention. As smartphones have benefitted from significant development over the last few years, it is now possible to capture various kinds of motion using a smartphone’s sensors, (e.g., accelerometer, GPS,

Earthquakes detection with optical fibers

2019 Joint Conference of the IEEE International Frequency Control Symposium and European Frequency and Time Forum (EFTF/IFC), 2019
The existing optical fiber network for telecommunication, together with coherent laser interferometry techniques such as narrow-linewidth lasers and heterodyne detection, is proposed as a tool for the detection of earthquakes. Using this infrastructure, we were able to detect several earthquakes, with moment magnitude as small as 3.4 and distances to ...

A setup for detecting earthquake precursors

Instruments and Experimental Techniques, 2015
A method for the short-term forecasting of earthquakes based on the simultaneous detection of neutrons and low-energy charged particles produced in the earth’s crust is described. Cherenkov and scintillation detectors and neutron counters are used in the setup. It is shown that this setup offers a chance to forecast earthquakes with a magnitude of over

Earthquake building damage detection with object-oriented change detection

2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013
Remote sensing image change detection is an effective method to estimate earthquake damage. With the improvement of spaceborne image resolution, single pixel is gradually replaced by object as the basic unit for change detection. The principle of object-oriented change detection method is described in this paper. And then data processing flow is stated.

SAR interferometry for detecting the effects of earthquakes on buildings

NDT & E International, 2002
In this paper, the authors describe an innovative application of radar interferometric techniques aimed at monitoring the structural changes induced by earthquakes on buildings. The application is based on the use of a ground-based instrumentation, able to operate as interferometric synthetic aperture radar.
