Why do you hear an earthquake before you feel it?

It’s harder for the energy to move through the Earth’s crust as shaking than it is to move through the air as noise. Because of this, in general, more people can hear an earthquake than can feel one since the noise travels farther from the epicenter than the shaking.

Why are there Moonquakes?

– Shallow moonquakes, quakes at the surface of the moon (20-30 kilometers deep), likely caused when the moon’s crust slips and cracks due to the gradual shrinking or “raisining” of the moon as it cools. – Meteor impacts, vibrations caused when meteors crash into the surface of the moon.

Can dogs really sense earthquakes?

Dogs have a wider hearing range and better scent detection than humans. Some scientists suggest that dogs can hear seismic activities that precede earthquakes (such as the scraping, grinding, and breaking of rocks underground). If their hearing is impaired, they are less likely to detect quakes, Coren writes.
