Astronomers, especially those involved in public outreach programs, are used to answering these questions. However, when believers in various mystical systems use alignments as evidence for their own beliefs, many astronomers are at a loss to explain why the

Richter magnitude scale and energy equivalents in terms of TNT explosive force


The following table lists the approximate energy equivalents in terms of TNT explosive force – though note that the earthquake energy is released underground rather than overground.[21] Most energy from an earthquake is not transmitted to and through the surface; instead, it dissipates into the crust and other subsurface structures. In contrast, a small atomic
