Notes:
    - Red marker on last day shows latest data; data after this marker is from previous day.
    - Time is Coordinated Universal Time (UTC). Nepal Standard Time (NST) has a time offset from UTC of +5:45.
    - Relative amplitude is shown by the number of "counts" and black bar at the upper right of each plot.
    - The amplitude of the 25 April mainshock and other very large events are not plotted at their full scale relative to events on other days, since the amplitude scale automatically changes for each day depending on largest event in the day.
The background "whiteness" of the seismograms from 25 April and 12 May shows that their auto-amplitude scaling only allows larger shocks to be seen clearly. The same effect is apparent on 30 May, but this time it is due to large amplitudes from the M7.8, 680km deep earthquake SSE of Japan.
    - The mainshock and 12 May 2015 M7.3 aftershock also have apparent lower amplitude since they are "clipped" (the peak amplitudes exceeded the maximum recording range of the seismometer). [Alessandro Vuan ‏@avuan123: "the EVN station ground velocity clipping level is fixed at 0.5 - 0.6 cm/s - M7.8 true ground velocities were 1 order greater"]
    - Seismograms for the first week displayed, 18-24 Apr, give an indication of typical, background seismic recording at the EVN-Everest site of nearby and global earthquakes.
