What instrument is used to measure the intesity of an earthquake?
Earthquake to the millions of tonnes of rock removed in the mining process. The instrumental scales used to describe the size of an earthquake began with the Richter magnitude scale in the 1930s. It is a relatively simple measurement of an event's amplitude, and its use has become minimal in the 21st century. Seismic waves travel through the Earth's interior and can be recorded by seismometers at great distances. The surface wave magnitude was developed in the 1950s as a means to measure remote earthquakes and to improve the accuracy for larger events. The moment magnitude scale measures the amplitude of
Arizona's Instrument to Measure Standards the reading and mathematics scores must have been at least 1300). The changes in AIMS scholarships applied beginning with the graduating class of 2013. In 2007, the AIMS Test began to report out Lexile measures for students in grades 3-8 and 10. A Lexile measure can be used to match readers with targeted text and monitor growth in reading ability. Arizona's Instrument to Measure Standards Arizona's Instrument to Measure Standards (AIMS) was a standardized test administered by the state of Arizona. AIMS was a standards-based assessment aligned with the Arizona Academic Content Standards. In November, 2014, the Arizona State Board
