Question

Why do earthquakes seem to occur more often in the early morning or at night, rather than during the day?

Answer 1

They do occur during the day. The huge quake that hit San Franciso in 1989 happened around 5pm.

Answer 2

Quakes are caused by the shift of tectonic plates under the crust of the earth. I don't think time (in the traditional sence) has anything to do with it. Maybe just coincidence.

Answer 3

still a question for scientist, they are trying to find out... No one can answer.

Answer 4

The Oakland earthquake of 1989 occured at 5:04 p.m.

Answer 5

Earthquakes do not know time, they occur wherever and whenever, just more coincidence that you have noticed this.

Answer 6

They accour at every time. Maybe you are using only few examples.

Answer 7

Is that some kind of duck?

Answer 8

Ive never heard the earth 'quack'!!

Answer 9

There are millions of recorded earthquakes....you're looking at two...its not even a coincidence, you just haven't considered the rest of the data

Answer 10

0800 is early? you must lead a nice life. But the point I would like to make is this: they don't only happen "early" or during the night. 2 years ago, here in Taiwan, we had a big earthquake that killed several people and wounded many more, doung a fair bit of damage, and it was at about 3 in the afternoon. We get earthquakes almost daily and 24 horus a day. Most are too small to feel, or small enough that they do nothing but make you feel a little dizzy. We get them during school (I am a teacher) every 2 or 3 weeks.
