Each degree is divided into 60 parts each part is known as minute 4 mts means 1/15 of a degree.

Minute is a subdivision of degrees
it is not a unit ot time

Latitude, Longitude Coordinates of the epicenter (projection of the earthquake focus on the surface of the earth). The latitude is the number of degrees north (N) or south (S) of the equator and varies from 0 at the equator to 90 at the poles. The longitude is the number of degrees east (E) or west (W) of the prime meridian which runs through Greenwich, England. The longitude varies from 0 at Greenwich to 180 and the E or W shows the direction from Greenwich. Coordinates are given in the WGS84 reference frame.
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
