"India's southern most latitude is 8 degree 4 minutes N.What is meant by 4 minutes?"
Magnitude Magnitude type and value. Earthquake magnitude is a logarithmic measure of earthquake size. There are many different ways to compute magnitudes. They depend on how the amplitudes of the seismic phases are measured on seismograms and on which type of seismic sensor is used. Moreover each method only works over a limited range of magnitudes. The different magnitude types used here are:
ML : Local magnitude : Based on the amplitudes measured on crustal seismic phases adj ...more
