I'm answering this the old-fashioned way: with a current literature search (since January 2012)--
Deep-water bottom current research in the northern South China Sea using a reflection seismic method - (Acta Oceanica Sinica 2012-02) - ChinaEarthquake hazards: Putting seismic research to most effective use (Nature 783:7388) - California Traveling ionospheric disturbances: simulation and observation, the importance of latitudinal coupling of gravity wave-Perkins-Es layer instabilities and forcing from pre-seismic events (not yet in press) - Brasil An Introduction to the Regional Italian Project ProSisMu Devoted to the Seismic Protection of Ancient Masonry Structures (Enabling Technologies: Infrastructure for Collaborative Enterprises (WETICE), 2012 IEEE 21st International Workshop) - ItalySeismic Design Scope of Tower Structures for UHV Transmission Lines on the Zone of Earthquake Fortification Intensity 8 (Advanced Materials Research (Volumes 446 - 449) - Chinaand 13,000+ other entries, about equally divided between technologies to detect/predict earthquakes and methods to protect structures from earthquake damageok bascily ssientists don't now everthing about earthqaukes cause not everybody nows evertything ok scientists now when,howand why the earthqarkes comes so that's bascliy a good reason......
They do Not know how to predict when and where Earthquakes will occur in adequate time to give people enough warning in order to save lives.
a tool used by scientists to measure earthquakes by movement
200 BCE.
Seismologists are based on the study of earthquakes while Geologists study the earths core and quakes.
Moment Magnitude Scale :))
Because of the study of seismic waves from earthquakes
Scientists use seismographs.
The seismic waves that the earthquakes make travel slowly and scientists can track them
Yes they can but only a couple of minutes before it strikes. Scientists know where earthquakes could occur but the when is unknown until a few minutes beforehand.
scientists who study earthquakes
They do Not know how to predict when and where Earthquakes will occur in adequate time to give people enough warning in order to save lives.
By looking at the rocks and the way the layers of rock are stacked scientist feel they have pretty good idea of the time and severity of many past earthquakes.
Seismograph.
comparing rubber bands to earthquakes is not common almost all scientists do not compare those two.
Nobody. Currently we do not have any means of predicting earthquakes. Scientists who study earthquakes are called seismologists.
Nobody can know that for sure. Earthquakes are unpredictable and scientists have not been able to predict them at this time.
