Volcanoes.
The tectonic plate boundary at which volcanoes occur is primarily at convergent plate boundaries where one tectonic plate is subducted beneath another. This type of boundary is known as a subduction zone.
Volcanoes are formed by the movement of plates when one tectonic plate (usually an oceanic plate) is forced beneath another (often a continental plate) in a process called subduction. As the subducting plate sinks into the mantle, it undergoes increasing pressure and temperature. The heat and pressure cause the subducting plate to melt, forming magma. The magma is less dense than the surrounding mantle, so it rises through the overlying plate, eventually reaching the surface and erupting as a volcano.
Repeated eruptions and accumulation of volcanic material over time lead to the growth of a volcanic mountain. The exact type and characteristics of the volcano depend on various factors such as the composition of the magma, the presence of gases, and the type of plate boundary.

Earthquakes.
Earthquakes can occur at various types of plate boundaries, including transform boundaries, convergent boundaries, and divergent boundaries. Transform boundaries, where two plates slide past each other horizontally, such as the San Andreas Fault in California, are particularly prone to frequent earthquakes.
Earthquakes are caused by the movement and interaction of tectonic plates. At transform boundaries, the plates move horizontally in opposite directions and can become locked due to friction. As the stress between the locked plates builds up, it eventually overcomes the friction and releases in the form of an earthquake, causing the ground to shake. At convergent boundaries, as two plates collide and one is forced beneath the other, immense pressure and strain are generated, which can lead to powerful earthquakes. At divergent boundaries, where two plates move apart, the stretching of the crust can also generate seismic activity and result in earthquakes, albeit typically less powerful.
