Maximum intensity: At least MMI X Effects: Eastern half of the island most severely affected by Ground Failure.
Submarine Flow Failures may have caused tsunami, extensive landslide activity, rivers dammed.
Remarks: Damage reports from inhabited areas only, especially Port Royal; focus on damage to houses, death, and injury; details sketchy.
Locations of Failure:
1. Port Royal - classical examples of liquefaction; lateral spreading, ground oscillation, opening and closure of fissures, water ejected from fissures, submarine flow failures may have caused tsunamis, land connection destroyed.
2. Liguanea Plain - fissures, water ejected from 12 m deep wells, extensive landslide activity in Port Royal Mountains.
3. Spanish Town - liquefaction, details not known.
4. Portmore -Base of Saltpans Hills: water ejected from fissures in 20 or 30 places and continued until next day; Passage Fort: extensive liquefaction, details not known.
5. Clarendon - Water ejected from fissures some 19 km from the coastline, details not known.
6. Rio Cobre Gorge - Landslides in Sixteen Mile Walk dammed Rio Cobre, details not known.
7. Judgement Cliff - Major landslides, date uncertain.
8. Port Morant - Large landslides in the swampy area around Morant Point, details not known.
