An eruption strong enough to dislodge the shelf at La Palma is unlikely. Historically, the eruptions and general capacity for that region does not
lend to such large force.
The theory about the mega-tsunami is weakly constructed. Modeling used to come up with the theory in 2000 made assumptions that were greatly
exaggerated. If a volcano at La Palma erupts, it will have to be much stronger than the 7 eruptions before it:
* 1470-1492 Montaña Quemada
* 1585 Tajuya near El Paso
* 1646 Volcán San Martin
* 1677 Volcán San Antonio
* 1712 El Charco
* 1949 Volcán San Juan, Duraznero, Hoyo Negro
* 1971 Volcán Teneguía
Since I live on the east coast, I have read quite a bit about this theoretical scenario since I have a vested interest in it. I will admit, right now
I can only cite Wikipedia
for you, but the sources cited there should be enough to get you
pointed in the right direction. In essence, the mega-tsunami theory is blown way out of proportion and it would take a remarkably large eruption to
cause the type of displacement of water that would be needed to result in such a devastating tsunami.
Edit to add that it is unlikely but not impossible. I feel that if something on this scale were to happen, it would have to be preceded by some VERY
unusual activity. So far, what is happening in the Canary Islands is not that unusual. I'll panic when the activity at La Palma starts popping off a
series of mag 6+ quakes in a short timespan or notable geographic displacement occurs.
