Another perhaps useful notion here is that of earthquakes having epicentres and aftershocks. |
Seismic activity has occasionally been recorded in Kent, though the epicentres were offshore. |
The most persuasive evidence for the existence of subduction zones is the narrow Benioff zones of earthquake epicentres dipping away from deep-sea trenches. |
Rome was for a period one of the world's main epicentres of classical architecture, developing new forms such as the arch, the dome and the vault. |
