Effect of mental fatigue on induced tremor in human knee extensors [PDF]
, 2014 In this study, the effects of mental fatigue on mechanically induced tremor at both a low (3-6Hz) and high (8-12Hz) frequency were investigated. The two distinct tremor frequencies were evoked using two springs of different stiffness, during 20s ...

Earth, Planets and Space, 2017 In the present study, we analyze the seismic signals from a continuous volcanic tremor that occurred during a small phreatic eruption of the Hakone volcano, in the Owakudani geothermal region of central Japan, on June 29, 2015.

Inverse dynamics modelling of upper limb tremor, with cross-correlation analysis. [PDF]
, 2014 A method to characterise upper-limb tremor using inverse dynamics modelling in combination with cross-correlation analyses is presented. A 15 degree-of-freedom inverse dynamics model is used to estimate the joint torques required to produce the measured ...

Analysis of the intermittent volcanic tremor observed at Mt. Etna, Sicily during March-May 1987
Annals of Geophysics, 1996 Volcanic activity at the summit craters of Mt. Etna includes phreatic eruptions which jeopardize tourists and other people who sporadically approach the top of the volcano. To date no appreciable precursors of this kind of activity are known.

Fiber-Optic Observation of Volcanic Tremor through Floating Ice Sheet Resonance
The Seismic Record, 2022 Entirely covered by the Vatnajökull ice cap, Grímsvötn is among Iceland’s largest and most hazardous volcanoes. Here we demonstrate that fiber-optic sensing technology deployed on a natural floating ice resonator can detect volcanic tremor at the level ...

Geohazards in the Western Ionian Sea: Insights from Non-Earthquake Signals Recorded by the NEMO-SN1 Seafloor Observatory [PDF]
Oceanography, 2014 Seafloor instability resulting from both tectonics and volcanism affects the Western Ionian Sea. The NEutrino Mediterranean Observatory-Submarine Network 1 (NEMO-SN1), deployed 25 km offshore eastern Sicily at 2,100 m water depth, records a variety of ...

Tremor and its duration‐amplitude distribution at Popocatépetl volcano, Mexico
Geophysical Research Letters, 2016 The duration‐amplitude distribution was calculated for the tremor observed at Popocatépetl volcano during episodes of activity in 2000 and 2012–2014. An exponential function was used to obtain a good fit for the duration‐amplitude distribution, and the ...

The spatial amplitude distribution of volcanic tremor at Stromboli volcano (Italy)
Annals of Geophysics, 1996 A portable seismic station consisting of a three-component seismometer in conjunction with a spectral analyzer was deployed in May and June 1994 to record volcanic tremor in a wide area on Stromboli. For the reduction of path effects, tremor spectra were
