@USGS_Quakes mechanism shows this to be in downgoing slab (probably?), not on meagthrust

#EarthquakeReport #EarthquakeToot for M7.0 #Earthquake offshore of #SolomonIslands

@USGS_Quakes models suggest modest chance for triggered landslides and high likelihood for induced liquefaction

#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
https://earthjay.com/?p=10493

#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

report here: https://earthjay.com/?p=10493

#EarthquakeReport #EarthquakeToot for M 7.3 #Earthquake near the Tonga trench #toottoot

no #Tsunami observed on tide gages

report here includes my interpretation and a regional tectonic summary:

#EarthquakeReport for the M 7.6 (likely) subduction zone #Earthquake in #Mexico on 19 Sept 2022 #TootToot #toot

catching up on reports that happened after my website went down

generated 0.6-1.7m wave height #Tsunami
probably triggered landslides/induced liquefaction

report (and higher resolution figures) here:
https://earthjay.com/?p=10472

#EarthquakeReport for M 6.9 #Earthquake in Taiwan on 18 September 2022

there was lots of damage and some casualties :-(

landslides and liquefaction models show that there was a high likelihood for these.
