Creep fronts and complexity in laboratory earthquake sequences illuminate delayed earthquake triggering

Nature Communications, 2022
Laboratory earthquake experiments reproduce delayed earthquake triggering, similar to aftershocks, as a result of propagating slow slip fronts. The speed of the fronts can be highly sensitive to fault stress levels left behind by previous earthquakes.

The global earthquake history

, 2014
The study of earthquakes from historical sources, or historical seismology, was considered an early priority for the Global Earthquake Model (GEM) project, which commissioned a study of historical seismicity on a global scale.

2022 Mw 6.6 Luding, China, Earthquake: A Strong Continental Event Illuminating the Moxi Seismic Gap

, 2023
On 5 September 2022, an Mw 6.6 strike-slip earthquake occurred in Luding, Sichuan, China. It illuminates the seismic gap on the southern end of Xianshuihe fault zone, that is Moxi segment, and is the most damaging earthquake in Chinese Mainland since ...

Distribution of low-frequency earthquakes accompanying the very low frequency earthquakes along the Ryukyu Trench

Earth, Planets and Space, 2017
This study investigated the activity and distribution of low-frequency earthquakes (LFEs) accompanying the very low frequency earthquakes (VLFEs) in the central and southern Ryukyu Trench.

Subdaily Slow Fault Slip Dynamics Captured by Low‐Frequency Earthquakes

AGU Advances, 2023
Geodetic positioning is the geophysical record of reference for slow slip events, but typical daily solutions limit studies of the evolution of slow slip to its long‐term dynamics.

Defining the Relationship between Seismicity and Deformation at Regional and Local Scales [PDF]

, 2013
In this thesis, I use source inversion methods to improve understanding of crustal deformation along the Nyainquentanglha (NQTL) Detachment in Southern Tibet and the Piceance Basin in northwestern Colorado.

Characteristic activities of slow earthquakes in Japan

Proceedings of the Japan Academy, Series B, 2020
Slow earthquakes are a recently discovered phenomenon that mainly occur updip and downdip of the seismogenic zones of great earthquakes along the subducting plate interface. The spatiotemporal activity of various slow earthquakes occurring in the Nankai subduction zone is characterized by along-strike heterogeneity and along-dip systematic changes ...

The High‐Frequency Signature of Slow and Fast Laboratory Earthquakes

Journal of Geophysical Research: Solid Earth, 2022
AbstractTectonic faults fail through a spectrum of slip modes, ranging from slow aseismic creep to rapid slip during earthquakes. Understanding the seismic radiation emitted during these slip modes is key for advancing earthquake science and earthquake hazard assessment.

How cold is too cold? A theoretical analysis of the optimal trigger for index insurance for frost damage to crops

American Journal of Agricultural Economics, EarlyView.
Abstract Crop insurance is undoubtedly an extremely valuable element in protecting agricultural businesses, but in many cases standard indemnity‐based products have had very low uptake due to high transaction costs elevating premiums to unaffordable levels.
