Convection currents in the asthenosphere
Science tries to explain the world. Many scientists study the movement of tectonic plates that cause earthquakes.
There are seven tectonic plates depicted in this setting.
Tectonic plates, 3 plates
There are 5 big tectonic plates and 12 other small tectonic plates. Totally make upto 17 tectonic plates. Also, known as 'Litospheric Plates', their movement is the main cause of Earthquakes.
Many scientists believe that the mantle convection hypothesis explains the great force needed to move tectonic plates. According to this theory, heat from the Earth's interior causes the mantle to flow in slow, circular currents, creating drag on the overlying tectonic plates. Additionally, the process of slab pull, where denser oceanic plates sink into the mantle at subduction zones, contributes significantly to the movement of these plates. Together, these mechanisms provide the necessary forces to drive plate tectonics.

Tectonic or lithospheric plates.
Many scientists believe that the hypothesis of mantle convection explains the great forces needed to move tectonic plates. This process involves the heat from the Earth's core causing the mantle to circulate, creating convection currents that exert force on the lithosphere. Additionally, slab pull—where denser oceanic plates sink into the mantle at subduction zones—also contributes to the movement of plates. Together, these mechanisms help account for the significant energy required to shift tectonic plates.
Earth is made up of many tectonic plates. When these plates shift, earthquakes happen. The tectonic plates are always moving, but most of the earthquakes are tremors (depends on how close you are to the place the tectonic plates are shifting).
Bali is located on two tectonic plates, the Australian Plate and the Eurasian Plate. These plates interact along the Sunda Megathrust, which can result in seismic activity in the region.
