it is more likely to have a strong earthquake where few recent earthquakes have happened
Yes it would.
Erupting volcanoes often create earthquakes before, during and after activity. Strong earthquakes are capable of 're-starting' volcanic eruptions.
the tectonic plates move around slightly until they clash causing strong vibrations or an earthquake

Japan it gets very strong earthquakes and may cause a tsunami
On average, there are around 500,000 earthquakes a year globally, but the majority of them are too small to be felt. It's estimated that about 100,000 of these earthquakes can be felt by people, with around 100-150 being strong enough to cause damage. The number of earthquakes per year can vary due to various factors.
Rarely, but it has happened before if there are strong winds and the blades fail to feather.
