A starquake is an astrophysical phenomenon when the crust of a neutron star undergoes a sudden adjustment, analogous to an earthquake on Earth. This is thought to be the source of the giant gamma-ray flares that are produced approximately once per decade from soft gamma repeaters. Spiral Galaxy ESO 269-57 Astrophysics is the branch of astronomy that deals with the physics of the universe, including the physical properties (luminosity, density, temperature and chemical composition) of astronomical objects such as stars, galaxies, and the interstellar medium, as well as their interactions. ... Cross section of a neutron star A neutron star is a type of degenerate star composed mostly of densely packed neutrons, generally about 25 km in diameter and as massive as an average star. ... Global earthquake epicenters, 1963–1998 An earthquake is a trembling or a shaking movement of the Earths surface. ... A soft gamma repeater is an astronomical object, now known to be a type of magnetar, which emits large bursts of gamma rays and X-rays at irregular intervals. ...
It is caused by tensions in the surface of the neutron star that arise from the collisions of certain heavy elements, like Iron, that are in a plasma-like state. Starquakes also occur much more rapidly than a normal earthquake.

A neutron star is a type of degenerate star composed mostly of densely packed neutrons, generally about 20 km in diameter and as massive as an average star.
Stars that are approximatly 1.4 to 3 times larger than the Sun collapse into neutron stars when they supernova.
A newborn neutron star can rotate several times a second; sometimes, when they orbit a companion star and are able to accrete matter from it, they can increase this to several thousand times per second, distorting into an oblate spheroid shape despite their own immense gravity (an equatorial bulge).
