The Uglovoye Podnyatiye Earthquake on December 20, 2018 (Mw = 7.3) in the Junction Zone between Kamchatka and Aleutian Oceanic Trenches

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2020
The paper presents the first results of integrated research of the strong seismic event (Uglovoye Podnyatiye earthquake (UPE) with a magnitude of Mw=7.3) that occurred on December 20, 2018 in the junction zone between the Kuril-Kamchatka and Aleutian ...

Shocklets, SLAMS, and field-aligned ion beams in the terrestrial foreshock [PDF]

, 2012
We present Wind spacecraft observations of ion distributions showing field-aligned beams (FABs) and large-amplitude magnetic fluctuations composed of a series of shocklets and short large-amplitude magnetic structures (SLAMS).

ARTEMIS Observations of Foreshock Transients in the Midtail Foreshock

Geophysical Research Letters, 2020
AbstractForeshock transients such as hot flow anomalies (HFAs) are frequently observed in the dayside foreshock. They can disturb the local bow shock, magnetopause, and consequently the magnetosphere‐ionosphere system through dynamic pressure perturbations. Recent multipoint observations found that such perturbations can even propagate from the dayside

Upper crust anisotropy of the 2020 Jiashi MS 6.4 earthquake

Frontiers in Earth Science, 2023
The 2020 Jiashi MS 6.4 earthquake occurred north of the 1997–1998 Jiashi earthquake swarm. Because of its complex tectonic environment and frequent strong earthquake occurrence, scholars have paid extensive attention to this area.

Prediction probabilities from foreshocks [PDF]

Journal of Geophysical Research: Solid Earth, 1991
When any earthquake occurs, the possibility that it might be a foreshock increases the probability that a larger earthquake will occur nearby within the next few days. Clearly, the probability of a very large earthquake ought to be higher if the candidate foreshock were on or near a fault capable of producing that very large mainshock, especially if ...

A semi-analytical foreshock model for energetic storm particle events inside 1 AU [PDF]

, 2014
We have constructed a semi-analytical model of the energetic-ion foreshock of a CME-driven coronal/interplanetary shock wave responsible for the acceleration of large solar energetic particle (SEP) events.

Ion Acceleration Inside Foreshock Transients [PDF]

Journal of Geophysical Research: Space Physics, 2018
AbstractRecent observations upstream of Earth's bow shock have revealed that foreshock transients can not only accelerate solar wind ions by reflection at their upstream boundaries but may also accelerate ions inside them. Evidence for the latter comes from comparisons of ion spectra inside and outside the cores, and from evidence of leakage of ...

Strain rate and temperature dependence of Omori law scaling constants of AE data: Implications for earthquake foreshock-aftershock sequences [PDF]

, 2004
Little is known about the temperature and strain rate dependence of acoustic emission AE activity (AE). Hence, we carried out a preliminary series of flow-through triaxial compression tests on porous sandstones at different temperatures and strain rates.

Foreshock migration preceding the 2016 Mw 7.0 Kumamoto earthquake, Japan

Geophysical Research Letters, 2016
We investigated the spatiotemporal evolution of an earthquake sequence following a series of large shallow intraplate earthquakes, including a Mw 6.2 foreshock and Mw 7.0 main shock, in the Kumamoto area of Kyushu, SW Japan.
