Urban seismic monitoring in Brasília, Brazil

PLOS ONE, 2021
Urban seismology has gained scientific interest with the development of seismic ambient noise monitoring techniques and also for being a useful tool to connect society with the Earth sciences. The interpretation of the sources of seismic records generated by sporting events, traffic, or huge agglomerations arouses the population’s curiosity and opens ...

Seismic monitoring of the Indian Ocean tsunami [PDF]

Geophysical Research Letters, 2005
The 26 December 2004 Sumatra‐Andaman earthquake of Mw 9.3 triggered a massive tsunami in the Indian Ocean. We here report on observations of the Indian Ocean tsunami at broadband seismic stations located on islands in the area. The tsunami induces long‐period (>1000 s) signals on the horizontal components of the sensor. Frequency‐time analysis shows

SEISMIC MONITORING OF BUILDING WITH BASE ISOLATION

Proceedings of the 7th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015), 2019
The seismic monitoring of buildings is important for two fundamental reasons: - evaluate the possible dynamic behavior of these structures during earthquakes; - gain experience on the general seismic behavior of the structures so that the experience and the database can be used in the future for design and analysis.

Seismic localization of elephant rumbles as a monitoring approach [PDF]

Journal of The Royal Society Interface, 2021
African elephants (Loxodonta africana) are sentient and intelligent animals that use a variety of vocalizations to greet, warn or communicate with each other. Their low-frequency rumbles propagate through the air as well as through the ground and the physical properties of both media cause differences in frequency filtering and propagation distances of

Active seismic monitoring [PDF]

Proceedings of the International Conference on Deep and High Stress Mining, 2012
The use of controlled sources of seismic radiation can facilitate a better understanding of the rock mass response to mining. Ideally, the seismic sources should be highly repeatable so that differences in seismic transmission over time can be more easily studied and related to mining.

Digital system for monitoring volcanic seismicity [PDF]

2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings, 2015
To control and preventing volcanic risk, are used different devices where many parameters are monitored that provide insight into the state of a volcano. This paper presents the design of system for monitoring the volcano seismicity. This system is composed of the module of acquisition data, the power module, the peripherals for communicate remotely ...

Proactive Versus Reactive Seismic Monitoring in Mines - Results of a Seismic Monitoring Survey [PDF]

Proceedings of the International Conference on Deep and High Stress Mining, 2007
A survey was undertaken to examine the use of seismic monitoring in mines. The 20-question survey titled “Application of Seismic Monitoring” (ASM) was used for rating the design and operation of seismic systems, and the application of seismic data. The survey indicated that the design, operation and data processing is relatively well conducted at

Metasurface‐Enabled Active‐Like Passive Radar

Advanced Science, EarlyView.
A programmable space‐time‐coding metasurface embeds distinct spatiotemporal tags into ambient wireless signals, allowing passive radar to operate in an active‐like manner. By enabling code‐correlated reconstruction under interference, the approach supports robust real‐time UAV tracking in complex environments and points to intelligent, low‐power ...

Seismic and Infrasonic Monitoring

, 2015
Seismology and infrasound are important and effective tools for monitoring volcanoes and forecasting eruptions. In the past two decades there have been over 25 successful forecasts. Well-monitored volcanoes have six or more local seismic stations within 15 km and several regional stations (>15 km) which are able to detect volcanic earthquakes of M∼0 ...

Optimizing Strategies for Non‐Invasive Prospection of Settlements in the Intertidal Zone: A Case Study From the Centre of the Drowned Medieval Village of Tolsende (Scheldt Estuary, the Netherlands)

Archaeological Prospection, EarlyView.
ABSTRACT Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited ...
