as i sit watching the epic seas of the current moment driven by high winds blowing south from the north/north-east on #madeira - that has been sufficiently strong that it threw a corrugated steel roof section around right near my cottage, up the hill, and the other night a collapse of a very large rock in the midst of a lot of relatively loose soil and sedimentary rocks
i am thinking about what level of risk there is, objectively, for me to find myself in a full washed-away tsunami at my position (about 200m altitude, 500m from the coast)
the incident mentioned at the top, the most notable one in recent history, was a tsunami on a very tall section of coastal land called Cabo Girao, it is adjacent to Camara do Lobos, one of the first large urban areas you reach on the road from Sao Vicente going towards Funchal
i took the route over that hill of Cabo Girao a few months back when i bought that mountain bike that is sitting mostly idle in my front yard, and it is hella tall and steep, and indeed, it has quite a steep cliff face on one side, the most notable thing i encountered on the way up there was a british owned holiday accommodation complex, a sprawling place with dozens of two and three storey buildings...
there was 19 fatalities from this incident, which isn't really relatively that hazardous, but being that i am close to a relatively steep part of the edge near the coastline, there is some danger of landlslides
thinking it through, i think that probably the chances are pretty slim that a big enough chunk of rock might fall off the peak across the gully from me, Arco Sao Jorge might drop a big chunk into the water and cause some big waves here
additionally, precisely because this island is so steep around its foundations under the water, dropping to hundreds of metres deep within less than a hundred metres of distance, really big waves coming in at us from afar have a really big area to push on before they actually ride up the side of the mountain and potentially wash away loads of loose soil
it's just a mental exercise for me to model what my risk level is, and i think it's pretty low overall, and landslides, also, prettyt low chance of a problem since it's only another 50m further up to the peak and it's quite a small body, and i think its shape is more steep on the other side than here, so a landslide up there is unlikely to have much effect down here at all
i still would be screwed in a pole shift if the water sloshed up more than 200m though, doesn't have to be fast, if it's big and powerful
