Earthquakes are common on the West Coast, with multiple plate boundaries like the San Andreas fault making geologic activity more likely. They are rarer on the East Coast, but they do happen .
Seismology (/ s aɪ z ˈ m ɒ l ə dʒ i, s aɪ s-/; from Ancient Greek σεισμός (seismós) meaning "earthquake" and -λογία (-logía) meaning "study of") is the scientific study of earthquakes (or generally, quakes) and the generation and propagation of elastic waves through planetary bodies.
The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. In its most general sense, the word earthquake is used
A fault plane is the plane that represents the fracture surface of a fault. A fault trace or fault line is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. [3] [4] A fault zone is a cluster of parallel faults.
Basic Fault is a theory created by Michael Balint, which suggests that every human's basic fault is caused in one's childhood. Specifically, a negative event or trauma that occurs in one's childhood between them and an adult, causing a fixation on objects, intense and often overwhelming emotions and the incapacity to deal with stress.
Both of the recent earthquakes struck near one of California’s lesser-known regions of tectonic activity, known as the Almanor Fault Zone. “Most faults are actually zones, at different scales ...
Seismotectonics is the study of the relationship between the earthquakes, active tectonics and individual faults of a region. It seeks to understand which faults are responsible for seismic activity in an area by analysing a combination of regional tectonics, recent instrumentally recorded events, accounts of historical earthquakes and geomorphological evidence.
As illustrated, an earthquake zone may start as a single crack, growing to form many individual cracks and collections of cracks along a fault. The key to fault growth is the concept of a "following force", as conveniently provided for interplate earthquakes, by the motion of tectonic plates. Under a following force, the seismic displacements ...
