An earthquake in an unpopulated area would cause little damage- in a major city, a great deal of damage.
Earthquakes can be measured on different scales because there are different ways to quantify their size and impact. The two commonly used scales are the Richter scale and the moment magnitude scale, which are based on different aspects of the earthquake, such as the amplitude of seismic waves or the total energy released. This is why you may see the same earthquake measured with different magnitudes on different scales.
Earthquakes usually occur at plate boundaries, e.g. Pacific Ring of Fire, where the plate collide into each other and create shockwaves that rock Earth's surface.See related question for more details.
Faults play a critical role in many earthquakes as they are the planes along which the Earth's crust ruptures and releases stored energy. When the stress between the two sides of the fault overwhelms the friction holding them together, the fault slips, causing seismic waves to radiate outward and result in an earthquake. Different types of faults, such as normal, reverse, and strike-slip faults, can generate different magnitudes and types of earthquakes.
Many earthquakes occur every single day. Most of them are tiny and even people living nearby can't feel them, or at least don't realize they're anything more than trucks driving by on the highway. If you'd like a continuously updated list of the most recent earthquakes, I recommend the US Geological Survey's earthquake site. A link is in the related links section below.
Greece experiences many earthquakes each year, ranging from small tremors to larger, more destructive ones. The frequency of earthquakes varies throughout different regions of the country.
Yes, two vectors of different magnitudes can give a zero resultant if they are in opposite directions and have magnitudes that cancel each other out when added together. This is known as vector subtraction.
The magnitudes of momenta are equal since momentum is a vector quantity, determined by both magnitude and direction. If the direction of the momenta are different, the magnitudes will depend on the angle between them.
Yes, two vectors with different magnitudes can be combined to give a zero resultant if they are in opposite directions. However, it is not possible for three vectors with different magnitudes to give a zero resultant because they must have specific magnitudes and directions to cancel each other out completely.
If all magnitudes are different, then minimum is three.
It is certain that two vectors of different magnitudes cannot yield a zero resultant force.

The symbol commonly used to represent small earthquakes on seismic maps and reports is a small circle or dot. This symbol may vary in size or color depending on the earthquake's magnitude, with smaller dots indicating lesser magnitudes. Additionally, some seismic agencies may use specific color codes to differentiate between different intensity levels of earthquakes.
-- The minimum magnitude that can result from the combination of two vectors is the difference between their magnitudes. If their magnitudes are different, then they can't combine to produce zero. -- But three or more vectors with different magnitudes can combine to produce a zero magnitude.
