Seismic waves from large earthquakes have been shown to trigger seismicity distances a mainshock, and this is termed remotely or dynamically triggered seismicity. We performed global search for potentially by the seismic 2011, M9.0, Tohoku‐Oki, Japan Earthquake. Using seismograms networks an event catalog, we tremors instantaneously during passing of waves, as well statistically significant changes in local rates after waves. For earthquakes, find potential cases instantaneous triggering...

Coulomb stress calculations based on preliminary data and models suggest that the magnitude-7.5 shock Sürgü Çardak faults was brought closer to failure by magnitude-7.8 rupture East Anatolian Fault, 110 kilometers south.
Brought closer to failure by the Feb. 6, 2023, magnitude-7.8 shock, magnitude-7.5 shock that struck nine hours later caused aftershocks turn on in some zones and off others. But why both shocks nucleated secondary faults — one quite small, other misaligned for is unclear. Moreover, decades earlier, two independent groups noted heightened risk of large earthquakes approximate location event.
[1] Changes in the static stress can trigger nearby earthquakes that occur within a few fault lengths from causative event. Transient stresses caused by passage of surface waves commonly events at remote distances, yet little is documented or understood about processes and necessary for triggering. To understand environments behind remote, dynamic, triggering, we must decipher relation to local field conditions where triggered occur. In this study, model change passing Rayleigh Love causes...
We provide additional evidence of tectonic tremor in Cuba triggered by the 2010 M w 8.8 Maule, Chile, and 2011 w 9.0 Tohoku‐Oki, Japan, earthquakes. The high‐frequency signals are modulated long‐period surface waves, similar to tremors observed other tectonically active regions. able locate two sources Tohoku‐Oki earthquake near east–west trending Oriente fault around Guantanamo Bay. Bay was primarily a Love wave Maule mainshock, both Rayleigh waves mainshock. This is consistent with...
Empirical studies with earthquake catalogs suggest that large events ( M > 5) are rarely triggered in significant numbers by passing surface waves at remote distances from main shocks. Triggered, small (M < earthquakes routinely associated the passage of 7) Since involve larger rupture areas, we study spatial and temporal characteristics dynamic stress change for clues. Using a 3D finite element method, model complete wavefield 2002 = 7.9 Denali recorded near Wasatch Front Utah, where...
Aftershock forecasts can help reduce seismic risk by communicating how many aftershocks be expected following a large earthquake, and the number of evolves over time space. Prior work finds that graphical forecast products may communicate this information better than only text or numbers. To identify which visual serve numerous user groups, we held workshops with members target professions, including emergency managers, engineers, critical infrastructure operators, science communicators,...
Abstract We report the first evidence for detection of a slow slip event in Longitudinal Valley, eastern Taiwan. The event, which lasted about 3.5 days, has been detected by borehole strainmeters. It occurred at shallow depths (about 2 to 4 km), either on Valley Fault or Central Range Fault. Here we investigate whether occurrence was influenced transient and periodic stress perturbations, particular June 2013 M w 6.2 Nantou earthquake, 60 km away 6 days prior event. Modeled changes Coulomb...
We analyze the seismicity in northern Baja California, Mexico, that occurred one month before and after 11 March 2011 ( M w 9.1) Tohoku‐Oki, Japan, earthquake for two other large remote earthquakes, 27 February 2010 central Chile w 8.8) April 2012 Sumatra w 8.6). The region of California exhibits high microseismic activity moderate‐size earthquakes. this is monitored by seismic network Red Sismica del Noroeste de Mexico (RESNOM) operated Centro Investigacion Cientifica y Educacion Superior...
A sequence of intraplate earthquakes occurred in Arizona at the same location where miningexplosions were carried out previous years. The explosions and some generatedvery similar seismic signals. In this study Dynamic Fourier Analysis is used for discriminating signalsoriginating from natural mining explosions. Frequency analysis seismogramsrecorded regional distances shows that compared with earthquake signalshave larger amplitudes frequency interval ~ 6 to 8 Hz significantly smaller inthe...
Financial and geophysical data, like many other low high frequency time series, are known to exhibit some memory effects. These effects may be long or short, permanent temporal depending on the event that is being modeled. The purpose of this study investigate characterized by financial market closing values volcanic eruption series as well relation between self-similar models used Lévy process. This paper uses highly effective scaling methods including processes, Detrended Fluctuation...

Abstract In many regions of the world with complex seismic activity, availability stations is limited. This motivated us to develop a probabilistic method for single‐station earthquake location. Single station location methods may provide an efficient and cost‐effective way monitor small‐magnitude events over large areas world. relies on outputs two neural networks, which predict initial spatial specific (convolutional) used in prior probability phase recognition (combination convolutional...
