1987/1988 Gulf of Alaska Earthquakes Archive:
The 1987-88 Mw 7 Gulf of Alaska earthquakes, among the largest oceanic intraplate earthquakes ever recorded, involved strike-slip faulting along a pre-existing zone of weakness inherited from plate formation processes. In a seminal paper, John Lahr argued that the earthquake sequence reflects fragmentation of the corner of the Pacific plate in its collision with the North American plate.
