A tiltmeter on Mauna Loa, used to predict eruptions by measuring very small changes in the profile of the mountain. A tiltmeter is a sensitive inclinometer designed to measure very small changes from the vertical level, either on the ground or in structures.
In astronomy, axial tilt, also known as obliquity, is the angle between an object's rotational axis and its orbital axis, or, equivalently, the angle between its equatorial plane and orbital plane. It differs from orbital inclination.
