tec·ton·ic boundary

(tĕk-tŏn′ĭk)
In the theory of plate tectonics, a boundary between two or more plates. The plates can be moving toward each other (at convergent plate boundaries), away from each other (at divergent plate boundaries), or past each other (at transform faults). Maps of seismic and volcanic activity across the Earth indicate that most earthquakes and volcanic eruptions occur along or near tectonic boundaries. Scientists believe this is due to the scraping, pushing, pulling, and melting of the Earth's outer layer (the lithosphere) along these boundaries.

The San Andreas Fault is the tectonic boundary between the Pacific Plate and the North American Plate, and seismologists have often predicted a 'Big One' could happen in the area in the future.
At the same time he cautioned that the northern parts of country had a proximity to the active tectonic boundary of the Arabian and Eurasian plates that elevated the probability of greater seismicity in that region when compared to the central and southern parts.
However, the northern parts of the country have a proximity to the active tectonic boundary of the Arabian and Eurasian plates that increases the probability of greater seismicity in this area when compared with the central and southern parts.
The Mid-Cayman Rise is an undersea ridge at the tectonic boundary where the North American Plate and the Caribbean Plate are spreading apart, and magma from Earth's interior wells up to form new crust at the seafloor.
ccording to the study, the answer depends upon the type of tectonic boundary.
In this country there used to be a tectonic boundary that ran right through the country, but the cracks have sealed up.

Researchers say that these two ridges may represent a new class of tectonic boundary, called an ultraslow-spreading ridge.
The presence of significant copper-nickel-cobalt mineralization associated with layered mafic intrusions, adjacent to a major tectonic boundary, suggests that Freewest had identified an area with similar exploration potential to the Voisey's Bay area of Labrador.
Both Utah and the Appalachians are on the North American plate, so there's no tectonic boundary between them.
