👉 Coseismic is a geological term that describes the transition from an earthquake to another type of seismic event, such as volcanic eruptions or landslides. It occurs when an earthquake occurs at a higher magnitude than the one it preceded and subsequently passes through the same region without any significant changes in its intensity or duration. This phenomenon can occur naturally or due to human activity, such as earthquakes caused by mining activities, building construction, and other forms of engineering. Coseismic events are important for understanding
