Earthquakes vary greatly in intensity. Many are not strong enough to cause any notable damage. Additionally, in some earthquake-prone areas the buildings are built to withstand earthquakes, and so are less likely to be damaged.
It all depends on how big the fault is, bigger ones will cause bigger earthquakes, while smaller, or small ones may cause no earthquake at all.
Earthquakes occur at all plate boundaries.
No single change occurs before all earthquakes.
Tsunami's can be triggered by earthquakes that happen underneath the ocean floor.
Any and all plate motion causes earthquakes.

arthquake hazard
The measurement of how likely an area is to have damaging earthquakes is called seismic hazard. It assesses the probability of ground shaking exceeding a certain intensity within a specific timeframe.
California next to Alaska, but California's quakes are more damaging.
Volcanoes produce volcanic eruptions and occasionally damaging earthquakes.
Earthquakes possess a unique way of damaging structures. Earthquakes vibrate and shake structures, never in just one direction. This chaotic back-and-forth movement is very harmful to architecture.

Mexico is located in a seismically active region. On average, Mexico experiences thousands of earthquakes each year, but most are small and go unnoticed by people. However, Mexico does occasionally experience larger, more damaging earthquakes.
NZ has earthquakes all the time. It is on a major fault line. . Earthquakes are fairly common in New Zealand, but fortunately not usually of damaging strength. The strongest earthquakes, up to Richter 7, are in Fiordland, an area essentially unpopulated. The Alpine Fault is expected to produce an earthquake >Richter 7 some time in the future, but forecasting is almost guesswork.
