Yes, earthquakes can indeed cause tsunamis. Tsunamis are typically caused by the movement of the ocean floor due to seismic activity, such as earthquakes. When a large, shallow earthquake occurs, especially one with its epicenter or along a fault line close to the ocean floor, it can displace a massive volume of water. This displacement generates waves, which can grow into tsunamis as they travel across the ocean. The most destructive tsunamis are often associated with earthquakes that happen in areas where tectonic plates are subducting, which means one plate is being forced under another at the boundary between the plates. read more >>

By far, the most destructive tsunamis are generated from large, shallow earthquakes with an epicenter or fault line near or on the ocean floor. These usually occur in regions of the earth characterized by tectonic subduction along tectonic plate boundaries.read more >>
