appears to be a tsunami recorded on the Honiara tide gage https://webcritech.jrc.ec.europa.eu/SeaLevelsDb/Device/1695

From the CalGov’s OES office birdsite:
#TsunamiReport Cal OES is closely monitoring the impacts of the earthquake near the Solomon Islands & is coordinating with the @NWS_NTWC.
There is NOT currently any expected impacts on our coasts in California.
However, ports & coastal communities should continue to check for updates.

Cocos Isle gage updated due to twitter peer review from Harold Tobin thanks!
also added Bintuhan record

#EarthquakeReport #EarthquakeToot #TsunamiReport for M 7.3 #Earthquake near Tonga Trench
Here are the plots for gages that the PTWC listed as having #Tsunami waves
Pago Pago record is clear, Nukualofa record is more noisy (is it a tsunami?).
Note the difference in scale on tsunami size axis (on the right)
updated these to the report

#EarthquakeReport #TsunamiReport for M 7.3 #Earthquake Tonga trench
I missed this since the gage is on the nodal plane for the earthquake. BUT there was a #Tsunami recorded on the Pago Pago #AmericanSamoa tide gage.
Here is a screenshot
