I. (adjective)
Sense 1
Meaning:
Subject to or caused by an earthquake or earth vibration
Synonyms:
seismal; seismic

Similar:
unstable (lacking stability or fixity or firmness)
Derivation:
seism (shaking and vibration at the surface of the earth resulting from underground movement along a fault plane or from volcanic activity)
Context examples:
The hard rock of ocean crust also generates crisper seismic images.

Slow-motion collisions of tectonic plates under the ocean drag about three times more water down into the deep Earth than previously estimated, according to a first-of-its-kind seismic study that spans the Mariana Trench, a crescent-shaped trench in the Western Pacific that measures 1,500 miles long and is the deepest ocean trench in the world.

Different materials can change the speed of seismic waves or reflect them, allowing scientists to use these waves to learn about the interior of the Moon and model its formation.

Their technique, which they had previously tested with fiber-optic cables on land, could provide much-needed data on quakes that occur under the sea surface, where few seismic stations exist.
