Earthquake-generated seiches can be observed thousands of miles away from the epicentre of a quake . Swimming pools are especially prone to seiches caused by earthquakes , as the ground tremors often match the resonant frequencies of small bodies of water . The 1994 Northridge earthquake in California caused swimming pools to overflow across southern California . The massive Good Friday earthquake that hit Alaska in 1964 caused seiches in swimming pools as far away as Puerto Rico . The earthquake that hit Lisbon , Portugal in 1755 caused seiches 2,000 miles ( 3,000 km ) away in Loch Lomond , Loch Long , Loch Katrine and Loch Ness in Scotland and in canals in Sweden . The 2004 Indian Ocean earthquake caused seiches in standing water bodies in many Indian states as well as in Bangladesh , Nepal and northern Thailand . Seiches were again observed in Uttar Pradesh , Tamil Nadu and West Bengal in India as well as in many locations in Bangladesh during the 2005 Kashmir earthquake
