Not always
Not necessarily. A small earthquake does not always indicate that a larger earthquake is imminent. Earthquakes are unpredictable, and it is not possible to accurately forecast when or where a larger earthquake will occur based on smaller ones.
Most small earthquakes are just background seismicity. There is no way to tell whether a small event will be followed by a larger one. But if there is a larger earthquake afterwards, the first earthquake is called a "foreshock"
A small earthquake
Do you mean earth tremor? That is a small earthquake, or an aftershock.
The small waves on a seismogram after an earthquake typically represent aftershocks or smaller tremors following the main earthquake event. These waves can vary in size and frequency but are usually less intense than the initial earthquake.
Nope. Don't believe it. Just because there was an earthquake in Japan doesn't mean we'll ALL die.
A tributary is a small river or stream which flows into a larger river.
I think you mean catastrophic, which means causing a great deal of damage. The earthquake was catastrophic for the small village.
Depends on whether the outlier was too small or too large. If the outlier was too small, the mean without the outlier would be larger. Conversely, if the outlier was too large, the mean without the outlier would be smaller.
the numbers are larger, but could mean less or more: 1/20000000 is small and 20000000/1 is large
It means that the earthquake is large and powerful.
