Going on the live feed it would appear buildings are now burning as a result of the extensive lava flow

This camera is currently panning around the area. The extent of the ongoing eruption is evident:

Lots of talk on social media about the possible Atlantic megatsunami that the scientists say could happen if the island was to split and cause a landslide into the ocean. Very low risk though.

Fortunately - or unfortunately if you prefer - the thesis has been debunked. Firstly, the chance of a huge chunk of La Palma sliding into the ocean is miniscule. Secondly, even if it did the resulting wave wouldn't be anything like the size the thesis claimed, and would largely dissipate before reaching the Americas.

The eruption is still going strong with regular explosions now audible on the YouTubes streams. Somewhat worryingly the more recent data suggestion that the ground is still inflating rapidly.

 Edit: that same website also mentioning increasing inflation (as you say)so contradictory in its reporting.

It was around 16cm yesterday morning. That is a massive amount of inflation and shows that magma is accumulating at a much faster rate than it is currently being released. Any inflation is bad news during an eruption.

I suspect there are a few twists and events to come in the near future.


I think once again the video footage will look impressive when the sun goes down. Sadly it is inevitable more houses will be destroyed.

Maybe another vent or two more will open in the coming days. Not great for those who live in the path of any lava flows, but nothing violent eruption wise.

The lava field from the La Palma eruption as of 20th September can be seen here:

Looks like a fairly narrow band, but eventually there will be no route between the north west and south west of the island without going all the way around the other side.

As far as I know the airport at La Palma remains closed due to ash currently. That aside the eruption is a bit unpredictable currently with a lessening of the intensity right now but an increase in quakes at around 10km. I’m not sure I would like to predict what will happen in the coming hours or days.

The eruption has recently restarted as vigorously as before, possibly a little more so. I feel it may be a little while before any decisions could be made about travel. Fingers crossed their plans can go ahead or that an acceptable alternative can be found.

Just a quick update to say that the lava flow reached the sea early this morning and continues to flow at a high rate. Earthquakes are also continuing at a depth that indicates further intrusion of magma in the region below the volcano.

If nothing else La Palma will be a slightly different shoe that it was before the eruption. Not unusual in the big picture for the Canaries, but the big picture usually takes many millennia.
