What the record says
NCEI’s account, from the sources it cites.
three earthquakes that occurred during the 19 November 2017 seismic crisis that occurred east of Mare Island: two very small tsunamis were triggered by the Mw = 6.3 and 6.6 foreshocks of the Mw = 7.0 earthquake, which triggered a tsunami reaching a maximum amplitude of 0.8m at Ouinne tide gauge. Despite their small amplitude, they are very well recorded and shown in Fig. 8. (reference #12506)
Every runup
Nearest the source first. Heights are above sea level at the time; a tide gauge reads half the wave’s full height.
