Attached is a slightly revised and more accurate labeling of the WLIN
24-hour seismograph display that I sent earlier. It turns out that the
signals from the M5.8 Andreanof event at about 04:03 on Aug. 16 and the
M5.6 Peru event at about 04:04 on Aug. 16 arrive at the WLIN station at
about the same time. I've changed the label to "Andreanof" because it
is the larger earthquake.
