Raspberry Shake Publications & Case Studies

“The new proposed methodology includes the use of existing well databases (with knowledge on minimum basement depth), topographic slope derived from Digital Elevation Models (as a proxy for both depth to basement and Vs30, integrated with geological maps) and near-surface Quaternary geological maps. The Horizontal to Vertical Spectral Ratio (HVSR) method and a statistics-based geological mapping tool (COHIBA) are used to integrate the various sources of data estimates.”

“Internal erosion is the most important failure mechanism of earth and rockfill dams. Since this type of erosion develops internally and silently, methodologies of data acquisition and processing for dam monitoring are crucial to guarantee a safe operation during the lifespan of these structures”

“This paper describes the relationship between bedrock depth (D) and site fundamental frequency (f0) in the Nakdonggang delta region in the southeastern part of the Korean peninsula. We collected borehole logs to confirm the thickness of the sediments and estimated the f0 at over 200 locations across the delta using the horizontal-to-vertical spectral ratio (HVSR, Vs30) method.”

“Between 2019 November and 2021 July, four induced earthquakes of local magnitude equal to or greater than than three were felt by the population of Strasbourg, France.”

“Cet article revient sur l’histoire d’Haïti pour présenter la construction de la notion de citoyenneté dans le pays et démontrer que, aujourd’hui, cette dernière n’est pas pleinement réalisée tant la coupure entre la population et l’Etat – parfois qualifié de « failli »- est forte.“

“L’île d’Hispaniola est située entre les plaques tectoniques Caraïbe et Amérique du Nord et traversée par des failles géologiques sismiquement actives, ce qui entraîne régulièrement des tremblements de terre importants (Scherer, 1912 ; Calais, 2020).“

“In a citizen seismology approach, the S2RHAI project used low-cost seismic sensors (Raspberry Shake) to (1) complement the national seismic network and (2) to improve risk perception, preparedness, and scientific knowledge of the population.“

“Technological advancements and the appearance of low-cost Raspberry Shake seismographs have enabled the development of citizen science seismic networks in many areas worldwide.”

“The operations needed to decarbonize our energy systems increasingly involve faulted rocks in the subsurface. To manage the technical challenges presented by these rocks and the justifiable public concern over induced seismicity, we need to assess the risks. “

“On January 12, 2010, Haiti was hit by one of the largest seismic disasters known to date. At the time, the culture and perception of seismic risk was low among the population and—because of the lack of seismic sensors in Haiti—so was seismological knowledge.”

“Between November 2019 and January 2021, a series of seismic events were felt by the population of the city of Strasbourg, France. The first main event (MLv 3.0) that occurred on November 12, 2019, was part of a seismic swarm (the southern cluster) that has been initiated a few days before, lasted four months, and was located by the BCSF-Rénass (EOST), below La Robertsau area at a depth of 5 km.”

“A low-cost seismic instrumentation system (LCSIS) has been implemented and validated for the structural health monitoring of South America’s first experimental 6-story light-frame timber building (Peñuelas Tower). Furthermore, coupling the LCSIS with relative humidity and temperature measuring system has allowed for investigating the ambient-induced variations of the building’s dynamic properties.”

“The Internet of things concept empowered by low-cost sensor technologies and headless computers has upscaled the applicability of vibration monitoring systems in recent years. Raspberry Shake devices are among those systems, constituting a crowdsourcing framework and forming a worldwide seismic network of over a thousand nodes.”

“A steadily increasing number of citizen seismological stations, often located in populated areas, record a plethora of man-made events. These events are especially of interest, when they are caused by criminal activity or man-made explosions. On 4 December 2021, during an attempted robbery of an automated teller machine (ATM) in Bonn-Röttgen, Germany, the burglars used explosions.”

“This paper presents findings from ongoing research that explores the ability to use Micro-Electromechanical Systems (MEMS)-based technologies and various digital communication protocols for earthquake early warning (EEW).”

“Raspberry Shake seismographs are commonly used in schools, by Shake community members, and other individuals having no formal training in seismology. The existence of this class of instruments highlighted the need for easy-to-use visualization and notification software to complement these devices.”

“Raspberry Shake (RS) seismographs offer the potential for affordable and citizen‐led seismic monitoring in areas with few publicly available seismometers, especially in previously quiescent regions experiencing induced seismicity. ”

“Separation of overlapping signals is an important task in signal processing, with application in music, speech, and seismic signal processing. We show that separation is possible also for seismic recordings, using techniques from machine learning (and even those recorded with a single sensor).”

“Scientific education of local communities is key in helping to reduce the risk associated with natural disasters such as earthquakes.”

“Most of what we know about Earth’s structure, dynamics, hazards, resources and exploration for raw materials comes from seismology.”
