👉 Plinian is a type of seismic wave that occurs when an object, such as a mountain or rock, moves at a constant speed perpendicular to its surface. This motion can be described by the equation:
v = (g
h) / r
where v is the velocity of the object, g is the acceleration due to gravity on Earth's surface (approximately 9.81 m/s^2), h is the height above sea level at which the object is moving, and r
