#EarthquakeReport #TsunamiReport for #OTD in 2018 M 7.5 #Earthquake offshore of #NewCaledonia #LoyaltyIslands

maybe related to 8/29/18 M7.1
extensional (normal) "outer rise" type earthquake
triggered M6.6 earthquake
generated modest tsunami

well, all day i have had it in my mind that the mag was M 7.4 and that is what i wrote for the ground failure and intensity interpreti e posters.

they are updated online and here is a tweet showing them.

here is the #EarthquakeReport:

https://earthjay.com/?p=11611

#EarthquakeReport #TsunamiReport for M 7.4 #Lindol #Earthquake offshore of #Mindanao #Philippines

compressional (thrust) earthquake
generated tsunami
@USGS_Quakes models suggest high chance for liquefaction
triggered slip near interface (?)

report here:
https://earthjay.com/?p=11611

#EarthquakeReport for M7.6 #Lindol #Earthquake offshore of the #Philippines

generated ~10cm amplitude (20cm wave height) tsunami at Davao Tide Gage (which is in a somewhat sheltered location compared to epicenter so probably larger tsunami along coast)

#EarthquakeReport for M7.6 #Lindol #Earthquake offshore of #Philippines

Pacific Tsunami Warning Center notification
Probably will generate tsunami in regions listed

2018 report has tectonic background information

#EarthquakeReport for M7.6 #Lindol #Earthquake offshore of #Philippines

High intensity, hopefully not much suffering
Reported intensity MMI 10
Probably will generate tsunami

#EarthquakeReport for M7.6 #Lindol #Earthquake offshore of #Philippines

Earthquake mechanism suggests event is on megathrust subduction zone interface
Probably will generate tsunami

https://earthquake.usgs.gov/earthquakes/eventpage/at00s51n9y/executive

#EarthquakeReport for M7.6 #Lindol #Earthquake offshore of #Philippines

@USGS_Quakes modeled intensity MMI 7
USGS model suggests widespread liquefaction
Probably will generate tsunami

#EarthquakeReport for M7.6 #Lindol #Earthquake offshore of #Philippines

Widely felt
Reported intensity MMI 7 so far
