Abstract We present an overview of the seismic networks, products, and services in Finland, northern Europe, challenges opportunities associated with unique combination prevailing crystalline bedrock, low natural intraplate background activity, a high level anthropogenic seismicity. introduce national local explain databases, analysis tools, data management concepts, outline Finnish macroseismi...

The extent to which ongoing seismicity in intraplate regions represents long-lived aftershock activity is unclear. We examined historical and instrumental seismicity in the New Madrid central U.S. region to determine whether present-day seismicity is composed predominantly of aftershocks of the 1811-1812 earthquake sequence. High aftershock productivity is required both to match the observation...

Compilation of almost 200 new maximum horizontal stress (SHmax) orientations in Texas reveals a complex intraplate stress field. A large extensional stress province is associated with extensive growth faulting from northeastern Mexico to Louisiana. SHmax is subparallel to the coastline, following the strikes of the growth faults. In contrast, we observe a strike-slip/normal faulting regime with...

For large earthquakes occurred at and around plate boundaries, we examined relations between seismic moment M 0 , fault length L, fault width W and average fault slip D, and found the following scaling laws. For interplate strike-slip events, the well-known L-cubed dependence of seismic moment M 0 breaks when L exceeds 30 km, and D and M 0 increase with L as D = L==(L+) and M 0 = WL 2 =(L +), r...

this research presents a numerical tool to estimate the green's function operator matrix of intraplate faults. having this matrix and its inverse, spatial distribution of fault slippage could be investigated through the inverse analysis of geodetic data. this information could be employed to predict the location of future powerful earthquakes. to implement fault sliding in fe calculations,...

Although much evidence points to a Late Mesozoic large silicic igneous province in SE South China (SESC), diverse Andean-type and non-Andean-type models have been proposed explain its origins. New age, isotope, trace element data on zircon from wells East Sea (ECS) offshore-onshore tectonomagmatic comparisons allow reassessment of the geodynamic interactions (ca. 200–86 Ma) between Cathaysia-ba...
