Increases in seismic activity around a volcano are typically caused by the movement of magma below the surface into a magma chamber. This causes increases in pressure which leads to fracturing to the rock mass around the magma chamber causing small earthquakes. If the pressure continues to build it would ultimately force the volcano to erupt.
As such the small earthquakes are potentially a warning sign of an impending volcanic eruption.

What does 3 mean on the Richter scale?
A rating of 3 on the Richter scale indicates a small earthquake that is generally not felt by people but can be recorded by seismographs. Such earthquakes typically release a minor amount of energy and are often referred to as "micro" earthquakes. They usually do not cause any damage and are mostly of interest to seismologists.
Does a volcano form an island and how can a volcano create a island mean the same thing?

Of or relating to earthquakes or other vibrations of the earth and its crust
When was new madrids last major earthquake?
Earthquakes occur in the New Madrid seismic zone every day. Most of them are so small (magnitudes 0, 1, 2...) that they can't be felt, only recorded by an instrument. The faults in the New Madrid seismic zone are active, producing these small events all the time. If you mean Madrid, Spain, you can do an earthquake search by googling "international seismological centre".
How many earthquakes have happened sense 1556?

Why is Australia not in an earthquake volcano area?
Because Austrailia is NOT on the Ring of Fire. The Ring of Fire is a "ring" where volcanoes and earthquakes mark. Also, Austrailia doesn't touch a plate, but I don't mean a DINNER plate. I mean a LAND plate. Earthquakes moastly happen when two plates overlap and shake the land or a volcano errupts.
Is there warning when a volcano is about to erupt?
In some cases, yes. A volcanic eruption is often preceded by earthquakes with unique signatures. A volcano preparing to erupt may also bulge outward. In some cases a volcano may start venting steam, or more steam than usual. Sometimes small steam eruptions may occur as rising magma boils groundwater. This is a complicated matter however. In some cases a volcano may show signs of erupting, but nothing will come of it.
Which country has the most earthquakes?
China typically has the most number of noticeable earthquakes annually.
What does the volcano name eyjafjallajokull mean?

Does a small earthquake mean that a larer earthquake is coming?
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"
What type of volcano is mount Tamboa?
