At a later time. When a seismic meter there is more resolution. Can measure the size of earthquakes have all information at a lower level 0 (for values that are less than 0 is considered to be negative) and higher 9
Later on, when seismic resolution greater. Details can measure the size of earthquakes. The lower level 0 (for values less than 0 is negative) and higher than 9.
later when the seismograph is more detailed. Can measure the size of earthquakes, detail, both in the lower levels 0 values less than (for 0 hold a negative value) and the higher 9
