local magnitude उदाहरण वाक्य

Because Richter scale measurements are to be taken only within about 300 miles of the quake epicenter, this measurement often is called the local magnitude.
The initial configuration was tested shortly after its installation when a relatively small ( 4.9 local magnitude ) earthquake occurred northwest of the building on November 4, 1976.
The "'1968 Inangahua earthquake "'struck west of local magnitude of 6.7, a surface wave magnitude of 7.4 making it the fifth deadliest earthquake in New Zealand's recorded history.
"We can get out the local magnitude in less than a minute, and we put that out first because it's the best thing we have at the time,"
The constant values in the equation are chosen to achieve consistency with the magnitude values produced by earlier scales, such as the Local Magnitude and the Surface Wave magnitude.

Ten days following the mainshock on July 31, a stronger aftershock occurred with a local magnitude of 5.8 and a maximum Mercalli intensity of VI ( " Strong " ).
Originally, Richter reported mathematical values to the nearest quarter of a unit, but the values later were reported with one decimal place; the local magnitude scale compared the magnitudes of different earthquakes.
The M5.3 June 1988 and the M5.4 August 1989 events ( local magnitude ) also occurred on previously unknown oblique reverse faults and were within of the M6.9 Loma Prieta mainshock epicenter, near the intersection of the San Andreas and Sargent faults.
Each of these is scaled to give values similar to those given by the local magnitude scale; but because each is based on a measurement of one aspect of the seismogram, they do not always capture the overall power of the source.
M _ \ text { L } ( local magnitude ) was not designed to be applied to data with distances to the hypocenter of the earthquake that were greater than 600 km ( 373 mi . ) . because the high frequency waves recorded locally have wavelengths shorter than the rupture lengths of large earthquakes.
