1. Epicenter: When an earthquake happens, the shaking originates from a point deep underground, called the focus. The epicenter is the point directly above this on the Earth's surface, and it's usually where the strongest shaking is felt.2. Focus: Also known as the hypocenter, this is the spot within the Earth where the earthquake actually begins. The rocks here break or move suddenly, causing the earthquake.3. Fault: A fault is a crack in the Earth’s crust where sections of rock have shifted. When these rocks suddenly move, it can trigger an earthquake.4. Seismic Waves: These are the waves of energy that spread out from the focus of an earthquake, shaking the ground as they travel.5. Plates: The Earth's surface is divided into huge slabs of rock, called tectonic plates, which fit together like a jigsaw puzzle. When these plates move or collide, they can cause earthquakes along faults.( Filipino Here!ฅ^•ﻌ•^ฅ )
