Seismonomics: Listening to the heartbeat of the economy
Abstract Seismometers continuously record a wide range of ground vibrations that are not necessarily related to earthquake activity, but are rather caused by human activity such as industrial processes and traffic. We isolate the human‐made imprints from a huge data set made of nearly 20 years of continuously recorded seismic data in Beijing, China ...

Validating a low-cost seismometer using a shaking table [PDF]
Ambient vibration measurement using a seismometer represent a non-invasive and non-destructive method for seismic-related studies. This method inhibits widespread applications, i.e., assessing site fundamental frequency, estimating bedrock level ...

Lab and Field Tests of a Low‐Cost 3‐Component Seismometer for Shallow Passive Seismic Applications
We performed laboratory tests and field surveys to evaluate the performance of a low‐cost 3‐component seismometer, consisting of three passive electromagnetic spring‐mass sensors, whose 4.5 Hz natural frequency is extended down to 0.5 Hz thanks to hyper ...

The Urban Seismic Observatory of Catania (Italy): A Real-Time Seismic Monitoring at Urban Scale
We describe the first dense real-time urban seismic–accelerometric network in Italy, named OSU-CT, located in the historic center of Catania. The city lies in the region with the greatest danger, vulnerability, and earthquake exposure in the entire ...

The Hydrometer as a Seismometer [PDF]
A SHORT time ago (NATURE, May 25) I directed attention to a misconception which seemed to prevail among seismologists as to the behaviour of a spirit-level. It may perhaps be useful to point out another fallacy, also of an elementary hydro-mechanical nature, involved in some of the unsuccessful attempts to record vertical motion.

PERFORMANCE OF RESONANT SEISMOMETERS [PDF]
A group of resonant vertical seismometers, each tuned to cover a part of the spectrum of microseism frequencies, has been operated for about one year. These instruments (a) clearly distinguish between simultaneous microseisms from two separate sources; (b) show an improved signal‐to‐noise ratio for microseisms from a single storm, permitting earlier ...

Research on the application of underwater node seismograph in land active source detection
The precise timing of the active source excitation is very important. In order to obtain more accurate excitation timing, we debugged and installed the underwater node seismometer observation system in the Liujiaxia active source, and recorded the ...

Autocorrelation of the Ground Vibrations Recorded by the SEIS‐InSight Seismometer on Mars
Since early February 2019, the SEIS (Seismic Experiment for Interior Structure) seismometer deployed at the surface of Mars in the framework of the InSight mission has been continuously recording the ground motion at Elysium Planitia.
