tremblors
Seismic ground movements
Tremblors are earthquakes or earth tremors.
The word is chiefly American and appears most often in news coverage of seismic events: A series of tremblors shook the region overnight.
The spelling tremblor (without the s) is the singular.
Some use trembler interchangeably, though tremblor predominates in journalism.
