- aftershock: A smaller earthquake that follows a larger earthquake in the same area.
- crust: The outermost solid layer of the Earth, forming the continents and ocean floors.
- disaster: A sudden event causing great damage, destruction, and loss of life, often natural.
- earthquake: The shaking of the Earth’s surface caused by a sudden release of energy in the Earth’s crust.
- epicentre: The point on the Earth’s surface directly above where an earthquake starts.
- faults: Fractures or zones of fractures in the Earth’s crust where blocks of rock move past each other.
- focus: The point inside the Earth where an earthquake rupture begins.
- hazard: A source of potential harm or danger, such as an earthquake or landslide.
- landslides: The downward movement of rock, earth, or debris down a slope, often triggered by earthquakes.
- liquefaction: When saturated soil temporarily loses strength and stiffness during shaking, behaving like a liquid.
- magnitude: A measure of the energy released by an earthquake, typically measured on the Richter or moment magnitude scale.
- Plate boundary: The edge where two tectonic plates meet, often associated with seismic and volcanic activity.
- Ring of fire: A major area in the basin of the Pacific Ocean where many earthquakes and volcanic eruptions occur.
- Richter scale: A logarithmic scale used to measure the magnitude of earthquakes based on seismic wave amplitude.
- Seismograph: An instrument that detects and records ground motion during an earthquake.
- tsunami: A series of large ocean waves caused by underwater disturbances such as earthquakes, landslides, or volcanic eruptions.
