Icequakes coupled with surface displacements for predicting glacier break-off

open access: yes, 2010
A hanging glacier at the east face of Weisshorn (Switzerland) broke off in 2005. We were able to monitor and measure surface motion and icequake activity for 25 days up to three days prior to the break-off.

A Quantitative Interpretation of Seismicity and Seismic Activity [PDF]

open access: yesGeophysical Journal International, 1967
Summary A new method for computation of seismicity has been worked out and the concept seismic activity has been mathematically formulated as an enlargement of seismicity. For computation of seismic activity a mathematical representation of the energy density function of an earthquake is needed.

A tectonomagnetic effect detected in Central Italy

open access: yesAnnals of Geophysics, 1994
Significant variations in the absolute value of the geomagnetic field intensity related to tectonic events, as earthquakes and volcanic eruptions, have been observed in several cases. To detect such a tectonomagnetic effect related to seismic activity, a

Photospheric and chromospheric magnetic activity of seismic solar analogs. Observational inputs on the solar/stellar connection from Kepler and Hermes

open access: yes, 2016
We identify a set of 18 solar analogs among the seismic sample of solar-like stars observed by the Kepler satellite rotating between 10 and 40 days.

Influence of seismic activity on the atmospheric electric field in Lisbon (Portugal) from 1955 to 1991 [PDF]

open access: yes, 2012
In the present study, we considered the influence of seismic activity on the atmospheric electric field recorded at Portela meteorological station (Lisbon, Portugal) for the period from 1955 to 1991.

四川锦屏水电站地区的剪切波分裂参数变化

open access: yesDizhen xuebao, 2018
通过分析四川锦屏水电站地区2012年1月至2013年12月库区的地震活动性和木里台的剪切波分裂参数变化,研究了水电站3次大规模蓄水对该地区地震活动性和地壳应力的影响. 结果显示:经3次蓄水,该地区的地震活动呈持续增强趋势,最终保持在较高水平,尤其是第二次蓄水之后,地震活动增强最为明显;木里台的快剪切波偏振方向在锦屏水电站3次蓄水前后表现出明显的变化.

Sensitivity to lunar cycles prior to the 2007 eruption of Ruapehu volcano [PDF]

open access: yes, 2017
A long-standing question in Earth Science is the extent to which seismic and volcanic activity can be regulated by tidal stresses, a repeatable and predictable external excitation induced by the Moon-Sun gravitational force.

Gasgeochemical indicators seismic activity [PDF]

open access: yesE3S Web of Conferences, 2017
Laboratory of Gasgeochemistry of POI FEB RAS is studying gas distribution in lithosphere, hydrosphere and atmosphere from 1977 years. Method consist is sampling from its in expedition, take gas from samples of sediment, water and atmosphere to use method degassing and analysis gas in chromatograph, to measure CH4, C2-C4, O2, N2, H2, He and some time Rn.
