Possible Tsunami Model for Recent 7.1 Aftershock and Delayed Effect at Same Site

[cph]

Might the recent 7.1 ‘aftershock’ at same site one month later, actually be a for shock of another pending earthquake?

Also might the delayed tsunami effect have been due to saucer sloshing effect? That is, if the sea bottom (saucer) is shaken, then water first sloshes towards the more open oceanic side, and then secondarily sloshes back to landslide; hence accounting for the delay? Might hydrodynamic simulations be of help? Hence would neither an ocean volume changing effect, nor an impulse effect be necessitated for this tsunami generation?

Here are two sites that explain how tsunamis form.

We don't have sufficiently detailed models of the subocean crust to predict earthquakes, nor their magnitude, location, or orientation. All the details come after the fact.

The 7.1 mag earthquake (38.253°N, 141.640°E, depth = 49 km (30.4 miles)) of April 7 was in the vicinity, but not the same location as the mag 9 earthquake (38.322°N, 142.369°E, epicenter depth = 32 km (19.9 miles)) of March 11.

Look for the 5 pointed star (it's orange, but should be yellow) in:

Look at the Seismicity profile and see the importance of location, orientation and depth.
