Rupture Process of the 26 May 2019 Mw 8.0 Northern Peru Intermediate‐Depth Earthquake and Insights Into Its Mechanism

open access: yesGeophysical Research Letters, 2020
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 ...

Recent Crustal Deformation in West-Central South America [PDF]

open access: yes, 2003
I use interferometric synthetic aperture radar (InSAR) to create maps of crustal deformation along the coast and within the volcanic arc of central South America. I image deformation associated with six subduction zone earthquakes, four volcanic centers,

Earthquake magnitude estimation from early radiated energy

open access: yesGeophysical Research Letters, 2008
From inspection of a large set of Japanese events, we investigate the scaling of the early radiated energy, inferred from the squared velocity integral (IV2) with the final magnitude of the event. We found that the energy can only discriminate whether the event has a magnitude larger or smaller than 5.8, and in the latter case it can allow for real ...

Toy model of accumulation and radiation of strain energy driven by big data of earthquakes

open access: yesJournal of Physics Communications, 2021
AbstractWe propose the pointwise toy-model, which demonstrates the accumulation and radiation of the (seismic) strain-energy. The calculated absorbed-seismic-energy is mapped to the accumulated strain-energy to balance the radiated strain-energy, because the accumulation of the strain-energy is caused by the subduction of one plate below another plate ...

Development of an Extended Hara Model for Mw Determination of Moderate-Magnitude Earthquakes

open access: yesInternational Journal of Technology, 2015
This study discusses the evaluation of Hara’s model to estimate seismic moment magnitude (MW) by using teleseismic waveform data, and then presents the development of an extended Hara model.

Strike-slip fault terminations at seismogenic depths : the structure and kinematics of the Glacier Lakes fault, Sierra Nevada United States

open access: yes, 2008
Structural complexity is common at the terminations of earthquake surface ruptures; similar deformation may therefore be expected at the end zones of earthquake ruptures at depth.
