Figure 2. The distance coverage of the data available for events of groups A to D. For
each event the source spectra retrieved from LVIG and, if available,
from PNIG (marked by filled circles and triangles, respectively) are
compared with the median spectrum obtained from all other stations of Mexican
seismological and accelerometric stations (shown by open circles). Group A and C
events provide an estimate of Q of the mantle wedge. Station
SCIG is marked by filled rectangles in the figure.
