Atlantic Ocean Tsunami Threat from Earthquakes, Landslides - Geology.com
WEBSome researchers believe that a large landslide in the Canary Islands could generate a tsunami with basin-wide impact. Faults on the southwest side of La Palma Island associated with Cumbre Vieja volcano could be the detachment surface of a mega-landslide (see satellite image below) .
How do landslides cause tsunamis? | U.S. Geological Survey - USGS.gov
WEBTsunamis are large, potentially deadly and destructive sea waves, most of which are formed as a result of submarine earthquakes. They can also result from the eruption or collapse of island or coastal volcanoes and from giant landslides on marine margins. These landslides, in turn, are often triggered by earthquakes.

What Causes a Tsunami? - Pacific Tsunami Museum
WEBTsunamis are caused by violent seafloor movement associated with earthquakes, landslides, lava entering the sea, seamount collapse, or meteorite impact. The most common cause is earthquakes. See the percentages on the right for the geological events that cause tsunamis.
