Relation between stress heterogeneity and aftershock rate in the rate-and-state model [PDF]

, 2006
We estimate the rate of aftershocks triggered by a heterogeneous stress change, using the rate-and-state model of Dieterich [1994].We show that an exponential stress distribution Pt(au) ~exp(-tautau_0) gives an Omori law decay of aftershocks with time ~1/

Establishment of landslide early-warning indicator using the combination of numerical simulations and case matching method in wushan open-pit mine

Frontiers in Earth Science, 2022
Landslides seriously threaten the safety of human life and property. In order to predict the on-set of potential landslides, this paper first characterizes the physical and mechanical parameters of rock mass on the basis of core rock quality designation ...

Triggered seismicity associated with the 1990 Nicoya, Costa Rica, M-w=7.0 earthquake [PDF]

, 2009
The 25 March 1990 (M-w = 7.0) subduction megathrust earthquake that occurred offshore the Nicoya Peninsula, Costa Rica, produced a large number of aftershocks on the subduction plate interface as expected and preceded an unusual sequence of earthquakes ...

A hybrid recognition model of microseismic signals for underground mining based on CNN and LSTM networks

Geomatics, Natural Hazards & Risk, 2021
Microseismic (MS) monitoring technology has been widely used to monitor ground pressure disasters. However, the underground mining environment is complex and contains many types of noise sources.

Would RC wide-beam buildings in Spain have survived Lorca earthquake (11-05-2011)? [PDF]

, 2016
Lorca earthquake (11-05-2011) is most destructive event recorded in Spain, causing nine fatalities and other severe consequences. Its important intensity was rather unexpected, and serious concern arose regarding risk of building stock in Spain.

Complex networks of earthquakes and aftershocks [PDF]

, 2004
We invoke a metric to quantify the correlation between any two earthquakes. This provides a simple and straightforward alternative to using space-time windows to detect aftershock sequences and obviates the need to distinguish main shocks from ...
