A major upgrade of the Global Strain Rate Map, version 2.1, uses far more geodetic data, systematic data processing, more modeled plates and plate boundaries, an improved algorithm, and a finer spatial grid than version 1 (Kreemer et al., 2014). We convert this model to an indefinite-term tectonic forecast of shallow seismicity on a fine global grid, using the assumptions of Bird et al. (2010) ...

Seismicity is a distributed process of great spatial and temporal variability and complexity. Efforts to characterise and describe the evolution of seismicity patterns have a long history. Today, the detection of changes in the spatial distribution of seismicity is still regarded as one of the most important approaches in monitoring and understanding seismicity. The problem of how to best descr...

A wide set of premonitory seismicity patterns is reproduced on a numerical model of seismicity, and their performance in prediction of major earthquakes is evaluated. Seismicity is generated by the Colliding Cascades Model, recently developed by the same authors. The model has a hierarchical structure. It describes the interaction of two cascades: a direct cascade of loading, which is applied t...

[1] Double Wadati‐Benioff seismic zones (DSZ) with two parallel planes of seismicity separated by 15–30 km are a global feature of subduction zones in the 50–200 km depth range. Upper plane seismicity is generally attributed to dehydration of the oceanic crust but the origin of the lower seismicity plane is debated. Serpentine or hydrous‐phase dehydration embrittlement is a commonly advocated m...

The observation of foreshocks preceding large earthquakes and the suggestion that foreshocks have specific properties that may be used to distinguish them from other earthquakes have raised the hope that large earthquakes may be predictable. Among proposed anomalous properties are the larger proportion than normal of large versus small foreshocks, the power law acceleration of seismicity rate a...

We present the results of relocating 17,544 hypocenters determined from data recorded during the 2016 Kumamoto Earthquake sequence, during the interval between April 14, 2016, and August 31, 2016. For this, we used a doubledifference relocation method to constrain high-resolution hypocenter locations by cross-correlation differential times as well as the NIED Hi-net catalog differential times. ...

Reservoir-induced seismicity is a very important issue in the study of geological analysis and ecoenvironmental impact assessment in hydraulic and hydropower engineering. On the other hand, reservoir-induced seismicity is a necessary consideration in the feasibility study of hydropower project. Due to the complexity in the process of reservoir-induced earthquake and the uncertainty of the influ...

There has been a significant increase in earthquakes in Central and Eastern US (CEUS) in recent years. This increase in seismicity has been associated with human activities like wastewater injection, and is referred to as induced seismicity. One of the components for hazard and risk calculation from induced seismicity is the level of ground shaking expected from an earthquake at a site of inter...

We present a case study of dynamically triggered seismicity in Idaho and western Montana from the 2002 MW 7.9 Denali fault earthquake to investigate the relationship between measured geological discriminants and propensity for triggering. We first establish triggering. We find events that are not reported in the Advanced National Seismic System catalog in Idaho and Yellowstone following the Den...

S U M M A R Y The geographical distribution of the (1981–2005) seismicity in southern California forms a ±150 km broad zone adjacent to the Pacific–North America plate boundary, ranging from depths of ∼1–∼30 km, with the bulk of the focal depths in the range of 2–12 km. The distribution of the seismicity that includes both mainshock–aftershock sequences and background events is affected by both...
