Searching for the effects of the May-June 2012 Emilia seismic sequence (northern Italy): medium-depth deformation structures at the periphery of the epicentral area

Annals of Geophysics, 2012
In 2012, a seismic sequence occurred in the lowlands of the Emilia-Romagna Region (northern Italy), between the borders of the Modena, Ferrara and Bologna Provinces.

EARTHQUAKE ENVIRONMENTAL EFFECTS, INTENSITY AND SEISMIC HAZARD ASSESSMENT: THE EEE CATALOGUE (INQUA PROJECT #0418) [PDF]

, 2011
Earthquake Environmental Effects (EEE) are the effects produced by an earthquake on the natural environment, either directly linked to the earthquake source or triggered by the ground shaking.

Modeling the Onset of Earthquake‐Triggered Landslides on Slip Surfaces Governed by Rate‐And‐State Friction

Geophysical Research Letters, Volume 51, Issue 24, 28 December 2024.
Abstract Earthquake‐triggered landslides are a severe hazard and contribute to landscape evolution. To understand their process and controlling factors, we model the onset of seismically‐triggered slip on pre‐existing slip surfaces governed by laboratory‐based rate‐and‐state friction, including wave propagation effects.

The Multi‐Segment Complexity of the 2024 MW ${M}_{W}$ 7.5 Noto Peninsula Earthquake Governs Tsunami Generation

Geophysical Research Letters, Volume 51, Issue 21, 16 November 2024.
Abstract The 1 January 2024, moment magnitude MW $\left({M}_{W}\right)$ 7.5 Noto Peninsula earthquake ruptured in complex ways, challenging analysis of its tsunami generation. We present tsunami models informed by a 6‐subevent centroid moment tensor (CMT) model obtained through Bayesian inversion of teleseismic and strong motion data.

Slip History, Tectonic Evolution, and Fault Zone Structure Along the Southern Alpine Fault, New Zealand

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 11, November 2024.
Abstract The study of active fault zones is fundamental to understanding both long‐term tectonics and short‐term earthquake behavior. Here, we integrate lidar‐enabled geomorphic‐geologic mapping and petrochronological analysis to reveal the slip‐history, tectonic evolution, and structure of the southern Alpine Fault in New Zealand.

Holocene Lake Sediments Reveal Alluvial Fan History With Links to Climate, Wildfire, and Earthquakes

Journal of Geophysical Research: Earth Surface, Volume 129, Issue 11, November 2024.
Abstract Flood hazards along alluvial rivers vary over time due to changes in both flow regime and channel morphology; however, their millennial‐scale histories are difficult to study from incomplete and poorly dated alluvial stratigraphies. Thus, the role of external forcings (e.g., climate) in the magnitude of alluvial channel dynamics remains poorly

Paleoseismology of the Northern Kongur Shan Extensional System, NE Pamir: Implications for Potential Irregular Earthquake Recurrence

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 10, October 2024.
Abstract The intricate and changing stress conditions within complex fault networks pose challenges in understanding earthquake recurrence and seismic hazards. The Kongur Shan Extensional System (KSES) in the northeastern Pamir, characterized by complex fault geometries and potentially variable surface loads in its surroundings, offers an ideal ...

Surface Rupture and Fault Characteristics Associated With the 2020 Magnitude (MW) 6.6 Masbate Earthquake, Masbate Island, Philippines

Tectonics, Volume 43, Issue 9, September 2024.
Abstract On 18 August 2020, Masbate Island was struck by a magnitude (MW) 6.6 earthquake. This seismic event represents the second occurrence of a strong earthquake (M > 6) in 17 years, emphasizing the necessity for further investigation into the characteristics of this event.

Unveiling the Mechanisms of the 1819 M 7.7 Kachchh Earthquake, India: Integrating Physics‐Based Simulation and Strong Ground Motion Estimates

Earth and Space Science, Volume 11, Issue 8, August 2024.
Abstract This study provided a comprehensive understanding of the source process of the 1819 M 7.7 Kachchh Indian earthquake using physics‐based dynamic rupture modeling and strong ground motion simulations. We successfully simulated the spontaneous dynamic rupture along a curved non‐planar fault using the 3‐D curved‐grid finite‐difference method ...
