earthquakes create seismic waves.
An earthquake could also be called a seismic event.
An archipelago is a cluster/group of islands (which Japan is). Seismic waves are the waves caused by movements of the Earth's plates, in other words, they are earthquakes. Japan is notorious/ well- known for the amount of earthquakes it has. This is why its called a seismic archipelago.
refraction event is a stright line and reflection is a hyperbolic event
Unlikely to experience a major seismic event
Earthquakes
It is more LIKELY to have a likely event than a UNLIKELY event.
A likely event, mathematically, is more then 50% likely to happen. An unlikely event is less then 50% likely to happen.

The distance of an epicenter from a seismograph station can determined by the time it takes for the seismic waves to reach each station. You need at least 3 seismic stations to record the event to determine this. The time taken for each seismic station to resisted the event will be different as they are different distances from the epicenter. The distance to the epicenter can then be calculated for each station and a epicenter can be determined by a triangulation from all stations that have registered the event.
japan, japan has a very advanced and sensitive seismic area and can record alot of earthquakes, but indonisia has had more in total
