tec·ton·ic boundary

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.

This data can be derived from the USGS tectonic boundary data and the distance measuring tool on Google Earth, as well as from the average velocity of a number of GPS ground stations from the NASA JPL GPS Time Series.
The study also found that this subduction zone was an extension of the same tectonic boundary that caused the 2004 Indian Ocean tsunami, which left at least 230,000 people dead.
Nepal sits over a tectonic boundary where the Indian Plate slips under the Eurasian Plate.
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.
The southernmost tectonic boundary of the range is the Surghar Fault that is moderately south dipping and emplaces Jurassic rocks over the shallowly folded Siwalik Group rocks of the Punjab Foreland.
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.
