which type of plate boundary is directly associated with massive earthquakes such as the devastating 1986 san francisco earthquake?
meandering plate boundaries

transform fault boundaries

Explanation:

The 1989 (not 1986) Loma Prieta earthquake in San Francisco occurred along the San Andreas Fault, which is a transform - fault boundary. Transform fault boundaries are where two tectonic plates slide past one another horizontally, and stress build - up and release at these boundaries can cause large earthquakes.
