High‐Precision Aftershock Distribution Highlights the Complex Fault Geometry of the 2024 Mw 7.5 Noto Peninsula Earthquake

Geophysical Research Letters
We deployed 30 temporary seismic stations around the source region of the 2024 Mw 7.5 Noto Peninsula earthquake to investigate the relationship between mainshock rupture and fault geometry.

Identification of Micro-Earthquake Hypocenters using Geiger and Coupled Velocity-Hypocenters Methods

International Journal on Advanced Science, Engineering and Information Technology, 2021
The accuracy location of hypocenter is needed to determine the subsurface character beneath a geothermal area. The study used 73 micro-earthquake events; each micro-earthquake event was classified based on the time difference between the P and S waves (ts-tp) that had values ≤ 3seconds, the magnitude of micro-earthquake ≤ 3SR and each micro ...

1-Dimensional Model of Seismic Velocity after Tarutung Earthquake 1 October 2022 Mw 5.8

Journal of Applied Geospatial Information, 2023
On October 1, 2022, an earthquake with a magnitude (M) of 5.8 occurred in the Tarutung region, Indonesia and was associated with an active fault at a depth of 10 km. The earthquake fault with dextral mechanism is suitable with the pattern of active fault

Micro-impact-induced mechano-chemical synthesis of organic precursors from FeC/FeN and carbonates/nitrates in water and its extension to nucleobases

Green Processing and Synthesis, 2023
Much effort was taken to elucidate how organic precursors appeared in early Earth, and attention was paid to two impact experiments: hypervelocity impacts by a propellant gun which simulated meteorite collides to Earth forming fatty acids and amino acids

Hypocenter location by pattern recognition [PDF]

Journal of Geophysical Research: Solid Earth, 2002
A novel approach to hypocenter location is proposed on the basis the concept of pattern recognition. A new data misfit criterion for location is introduced which measures discrepancies between the observed arrival times of an event and those of “nearby” previous events. In the arrival pattern misfit measure, travel times predicted by an Earth model are

ASSESSMENT OF THE LOCALIZATION OF HYPOCENTERS OF CRUSTAL EARTHQUAKES RELATIVE TO THE DEPTH AND RELIEF OF THE BORDER DENSITY STRATIFICATION IN THE CRUST OF THE NORTHEASTERN SECTION OF THE REFERENCE GEOLOGICAL-GEOPHYSICAL PROFILE 3-DV

Геодинамика и тектонофизика, 2017
The total length of the seismic profiles in the northeastern regions ofRussiaand, accordingly, the area of the territories covered by the seismic data interpretations, remains insignificant in comparison with the total area of these regions.

Faulting Mechanism of Tarutung Earthquake 2022 Mw 5.8 Using Moment Tensor Inversion

Journal of Applied Geospatial Information, 2023
On October 1, 2022, an earthquake with a magnitude of 5.8 shook the Tarutung area which was generated by an active fault at a shallow depth of 10 km. In this study, relocating the hypocenter and determining the mechanism of the earthquake was carried out
