From the Alentejo Coast around Porto Covo / Sines, up through to Setubal and Sesimbra to the south of Lisbon, then up to the Cascais coastal area, ocean view villa owners are not happy about the Portuguese Water Resources Ownership law (no. 54/2005) of 2005 (ratified in 2014), and are positively terrified about the prospects of the La Palma Mega Tsunami.
First, seaside villas in Porto Covo, Vila Nova de Milfontes, Sines, Zambuheira do Mar, Odeceix, Praia da Arrifana, Aljezur, Vila Nova de Santo Andre, Lagoa Formosa, Praia da Comporta, Soltroia, Troia Peninsular, Setubal, Sesimbra, Caixas, Lagua De Albufeira, Aroeira, Costa da Caparica, Cascais and San Joao do Estoril too close to the waterline are being targeted for destruction under law 54/2005!
Second, the massive land slip on La Palma is not about if as much as when 500 cubic kilometres of volcano will crash into the Atlantic Ocean, creating the largest tsunami in recorded history.

Alentejo oceanfront villas would obviously bear the brunt of any tsunami. And, if you think that this is just scaremongering, look up the 1755 Lisbon Earthquake and Tsunami; the Algarve and Alentejo Coastlines were wiped off the map, and that was from a regular tsunami with 6 meter high waves; the La Palma event could easily see waves in excess of 60 (sixty) meters come crashing into Porto Covo, Sines, Alentejo, Setubal, Sesimbra and Cascais areas. Forget tsunami warning applications on your smart phone or tablet, you still would be unlikely to get to high enough ground in time!
What is more, the Mediterranean fault line that created the 1755 earthquake and tsunami still could do the same again; the likely La Palma mega tsunami event is a separate issue. Another similar earthquake initiated 6 meter tidal wave would destroy many Sesimbra / Cascais area beachfront villas; that is, of course, if any are left standing as a result of law 54/2005!
