Since intraplate earthquakes are not near plate boundaries, give a general idea of what you think might cause them. Do the largest earthquakes cause the most deaths and the most damage to property? California is famous for earthquakes along the San Andreas Fault zone but there is another type of plate boundary where large earthquakes occur.
A pulsar is a neutron star that emits beams of radiation that sweep through Earth's line of sight. Like a black hole, it is an endpoint to stellar evolution. The pulses of high-energy radiation we see from a pulsar are due to a misalignment of the neutron star's rotation axis and its magnetic axis.ike a black hole, it is an endpoint to stellar evolution.

Astronomers have developed a solid model for the key stages of stellar evolution though many details are still being tested and refined. In this page we get an overview of the basic properties of the main types of stars, focusing on their sources of energy. This page is a condensed version of the stellar evolution section of the HSC Astrophysics option.
