Abstract Characterization of induced microseismicity at a carbon dioxide (CO2 ${\text{CO}}_{2}$) storage site is critical for preserving reservoir integrity and mitigating seismic hazards. We apply a multilevel machine learning (ML) approach that combines the nonnegative matrix factorization and hidden Markov model to extract spectral representations ...

Ionospheric VTEC anomalies before Ms7.1 Yushu earthquake
Vertical total electron content is examined to check whether the Ms7.1 Yushu earthquake on April 14, 2010, may have caused any anomalous ionospheric changes. The result shows two TEC increases over the epicenter vicinity on April 1 and 5; these anomalies

Twenty‐Five Years of Probabilistic Fault Displacement Hazard Assessment
Abstract Fault displacement hazard poses significant risks to critical infrastructure such as buildings, roads, and pipelines. While some structures can tolerate a certain degree of surface displacement, others, such as buildings, are far more vulnerable. Probabilistic Fault Displacement Hazard Assessment (PFDHA) quantifies the probability of exceeding

Frequency dependent attenuation of seismic waves for Delhi and surrounding area, India
The attenuation properties of Delhi & surrounding region have been investigated using 62 local earthquakes recorded at nine stations. The frequency dependent quality factors Qa (using P-waves) and Qb (using S-waves) have been determined using the ...

Abstract Analysis of conversions between compressional and shear waves is a workhorse method for constraining crustal and lithospheric structure on Earth; yet, such converted waves have not been unequivocally identified in seismic data from the largest events on the Moon, due to the highly scattered waveforms of shallow seismic events. We reanalyze the

Ionospheric disturbances around the time of the Ms7.0 Lushan earthquake
Variations of Vertical Total Electron Content (VTEC) in the ionosphere are investigated around the time of the Ms7. 0 Lushan earthquake. A time-series analysis shows an anomalous VTEC increase 15 days before as well as some anomalous VTEC decreases 5 ...

Wave Heating of the Solar Atmosphere
Magnetic waves are a relevant component in the dynamics of the solar atmosphere. Their significance has increased because of their potential as a remote diagnostic tool and their presumed contribution to plasma heating processes.

Abstract Subsurface wastewater injection has increased the seismicity rate within the Raton Basin over more than two decades, with the basin‐wide injection rate peaked between 2009 and 2015. To understand the evolution of injection‐induced earthquakes, we systematically analyzed 2016–2024 broadband recordings with a machine‐learning‐based phase picker ...
