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.
Sedimentology: the study of sedimentary rocks, strata, formations, eustasy and the processes of modern-day sedimentary and erosive systems. Seismology: the study of earthquakes. Structural geology: the study of folds, faults, foliation and rock microstructure to determine the deformational history of rocks and regions.
An earthquake – also called a quake, tremor, ... China stood out in several categories in a study group of 162 earthquakes (from 1772 to 2021) that included ...
These plates, called tectonic plates, can push against each other. Earthquakes are most common along fault lines, which are fractures that allow the plates to move.
Earthquakes create distinct types of waves with different velocities. When recorded by a seismic observatory, their different travel times help scientists locate the quake's hypocenter. In geophysics, the refraction or reflection of seismic waves is used for research into Earth's internal structure. Scientists sometimes generate and measure ...
The issue centers on a concept called hydroseismicity, the effect of water impacting earthquake faults. ... The study indicated that some of 121 earthquake swarms documented over a 24-year period ...
Here are some earthquake basics, like what earthquake magnitudes mean and how much damage each can cause.
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.
