On the puzzling feature of the silence of precursory electromagnetic emissions [PDF]
It has been suggested that fracture-induced MHz-kHz electromagnetic (EM) emissions, which emerge from a few days up to a few hours before the main seismic shock occurrence permit a real-time monitoring of the damage process during the last stages of ...

3D numerical simulation of hydro-acoustic waves registered during the 2012 negros-cebu earthquake [PDF]
The paper investigates on the hydro-acoustic waves propagation caused by the underwater earthquake, occurred on 6 February 2012, between the Negros and Cebu islands, in the Philippines.

Quantification of potential macroseismic effects of the induced seismicity that might result from hydraulic fracturing for shale gas exploitation in the UK [PDF]
The furore that has arisen in the UK over induced microseismicity from ‘fracking’ for shale gas development, which has resulted in ground vibrations strong enough to be felt, requires the urgent development of an appropriate regulatory framework.

We investigate the fault parameters of the 2005 Miyagi-Oki (Japan) earthquake using duration variations of teleseismic P-waves. The results show that the earthquake has a thrust-type mechanism and a seismic moment of 4.46 ¡_ 1019 Nm.

Earth’s gravity ― the reason of earthquakes
In the paper, an attempt has been made to describe seismic processes by means of classical mechanics. Dynamic parameters such as energy, impulse, and forces that determine the movement of masses are estimated.

Estimating Rupture Front of Large Earthquakes Using a Novel Multi-Array Back-Projection Method
A ruptured front obtained from high-frequency energy radiation is the key to understand the complex source. It is commonly observed that rupture fronts derived from different arrays often show some variations due to the obvious difference of the ...

The Mw7.8 Gorkha earthquake struck Nepal and ruptured the boundary between the Indian and Eurasian plates. We conducted 2‐D Pg wave tomography to clarify the seismogenic structure and try to understand causal mechanisms for this large earthquake, using ...

Radiated energy estimations from finite‐fault earthquake slip models [PDF]
AbstractRadiated seismic energy is expressed in terms of slip velocities by using an overdamped dynamics approximation. This formulation is used to estimate the radiated energy from earthquake finite‐fault models. A correction term is found to show that the approximation underestimates the radiated energy as defined by the full dynamics.

In the Nazca‐South American subduction zone, the subducted slab is flattened beneath northern Andes, called the Peruvian flat slab. The 2019 Mw 8.0 northern Peru intermediate‐depth normal‐faulting earthquake occurred at the leading edge of the Peruvian ...
