Do you mean the center of the earthquake?
If so, it is the hypocenter (focus)
Answer:
The correct answer is B. Migrating centers of low pressure in the Northern Hemisphere are also called tropical cyclones.
Explanation:
A tropical cyclone is a stormy formation generated by hot water bodies that evaporate in areas of low pressure and strong winds. This combination generates dense and warm clouds, that when colliding with the cold winds of the heights and the low atmospheric pressures develop intense storms that are fed back with the water that continues rising from the surface of the ocean. Thus, the cyclone grows in size and, driven by the coriolis effect, begins to rotate on its axis and acquire greater speed.
