Sea-bottom deposits formed by massive slope failures where rivers have deposited
large deltas. These slopes fail in response to earthquake
shaking or excessive sedimentation load. The temporal correlation of turbidite
occurrence for some deltas of the Pacific Northwest suggests that these
deposits have been formed by earthquakes.
|Turbidites (interbedded with mudstones/siltstones)
from the Ross Sandstone Formation Turbidite system of Namurian age
in County Clare, Western Ireland. The sandstone beds were formed in
a deep basin by turbidites coming from a delta area.
