Earthquake Detection with tinyML

Seismological Research Letters, 2023
Abstract Earthquake detection is the critical first step in earthquake early warning (EEW) systems. For robust EEW systems, detection accuracy, detection latency, and sensor density are critical to providing real-time earthquake alerts.

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 ...

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.

Wavelet Analysis on Detecting Pulse-Like Earthquakes

AIP Conference Proceedings, 2008
A quantitative approach for identifying pulse‐like ground motions is proposed herein. It is based on the use of the wavelet transform which has the peculiarity to detect sudden jumps in time histories by separating the contributions of different levels of frequency. Moreover, it has the advantage of low computational cost. Three different wavelet‐based

Earthquake Fingerprints: Extracting Waveform Features for Similarity-Based Earthquake Detection

Pure and Applied Geophysics, 2018
Seismologists are increasingly adopting data mining and machine learning techniques to detect weak earthquake signals in large seismic data sets. The detection performance of these new methods, especially their sensitivity and false detection rate, depends on the choice of feature representation for waveform data.
