The [take out] radius of a neutron star quake. Keep in mind that the richter scale is log based and a neutron star quake has been recorded as high as an equivalent 34 and would cause mass extinction to a radius of 10 light years. The distance from the earth to the sun is one AU. The distance from earth to pluto is about 40 AU. Earth to the farthest object in our solar system (the edges of the oort cloud at 120,000 AU) is roughly 1.87 lightyears. A neutron star quake would exterminate all life in all directions a little over 5 times the entire distance of our solar system. This all from a neutron star’s surface adjusting by a few micrometers in less than .000001 of a second. The earthquake that leveled San Fran and [took away] thousands of people in the early 20th century was a 7.4. Cool, now imagine a quake with destructive energy about 1,000,000,000,000,000,000,000,000,000 stronger.
