Not a barrier but certainly must influence propagation of tsunami waves. We learned in 2004 event how seafloor depths can direct or disperse tsunami waves

DART buoys are used to confirm tsunamis, here's a diagram showing how they work and some locations relative to recent M 8.8 quake. Need to maintain these and keep data flowing. Ocean observations keep people safe and informed. Don't let them go away in budget cuts. @geocollaborate.bsky.social πŸ§ͺ🌊

So…how’s your day going? The Pacific is on fire..(referring to activity). GeoCollaborate is monitoring and sharing real-time data to decision makers! Ocean observations are so critical! How do you think NOAA confirms a tsunami? We can not afford to lose ocean observations! @elprager.bsky.social πŸ”₯πŸ§ͺ

Around 11:30 am local time, a magnitude 8.8 earthquake struck the offshore Kamchatka region at a depth of about 20 kilometers. The subduction zone quake caused severe shaking on the Kamchatka peninsula and triggered tsunami warnings and advisories around the Pacific. (1/n)

A plot of water level measured by an ocean buoy close to the Kamchatka Peninsula, between about 10 pm GMT on the 29 July and 10 am GMT on the 30 July. The green dots show measurements taken every minute, and the red line at around the 11:30 GMT mark shows measurements taken every 15 seconds. A series of higher frequency oscillations, peaking at around around plus/minus 1.5m, are clearly seen on top of the diurnal/tidal cycle between about 11:30 pm GMT on the 29th July and 2am GMT on the 30th July.

Thought it was worth looking up the DART ocean buoy data - here's the record for the buoy closest to the earthquake, which occurred around 11:25 GMT on the 29 July. Important information for estimating tsunami arrival times and magnitudes around the Pacific Basin.

Currently a Tsunami Watch (threat still being evaluated) for entire U.S./Canada West Coast following very large M 8.7) sub-oceanic quake near eastern Russia in West Pacific. Plenty of time to refine/crunch numbers further for West Coast, but more imminent threat closer to epicenter.

Great graphic Jeff to make this point. Accuracy of forecasts has increased tremendously but most people don't realize it. Covered this in our recent book. A very important FACT given the dramatic and dangerous cuts to NOAA! πŸ§ͺπŸŒ€
