La Cumbre Vieja Volcano in the Canary Islands

The volcano is putting on an AMAZING show!

The activity at the vents has strongly increased this morning. 

Tall lava fountains, reported up to 600 m tall, rise from the main vent, while others produce dense ash and lava spattering. 

Lava can also be seen flowing on the surface away from the cone.

 

This seems to correlate with an increase of earthquakes in the last 24 hours, after having being reduced in numbers yesterday. 

 

There were 4 quakes between magnitudes 4.0-4.7 alone in addition to 130 ones at magnitudes around 2.5-3.9.

One of the magnitude 4 quakes occurred early this morning at shallow depth of 13 km, which is thought to be the main reservoir of the magma before it rises to the vents.

 

Quakes precede phases of intensification?
It seems that such upticks of quake activity precedes phases with increased lava supply several hours later. 

 

This might fit into the following model: first, magma pressure at depth increases either by surges from new magma arriving there or from temporary blockages in the paths above, preventing a sufficient release of it at the eruption; then, the pressure on the surrounding rocks create new cracks and paths, which shows up as quakes. 3rd, the magma then then rises through new and existing conduits until it reaches the surface hours later.

Horrible, earth-shaking ROAR coming from the volcano:

Dutch was right about La Palma quake magnitudes reaching 5.0+

This morning's magnitude 5.1 event, which hit at 7.27 a.m., is the strongest-so-far tremor under the volcano since the seismic crisis followed by the ongoing eruption began in September.

It was felt all over the island, and if the depth is correct of only 26 km it deviates significantly from the depth layer around 35-40 km, which has been where other stronger quakes in the range of magnitudes 4.5-5 that have occurred so far.

This could be due to new magma intrusion into intermediate layers at this depth. 

 

It will be important to see whether it will be followed by an increase of lava activity in the near future (several hours from now possibly).

So far this morning, there have been twenty-five 3.0+ quakes

one 4.0+ and one 5.0+

 

Ash emissions remain at very high levels.

Day 51 of the eruption.   Here is the latest news, and some great views of La Palma's

scenic beauty.

This is the best article I have read, not just about La Cumbre Vieja, but about volcanoes, in general.

How to read the signs of an eruption

 

The Spanish island continues to experience earthquakes and lava flows, but there is already talk of “positive” developments that might mean the worst is over. Here’s how experts are interpreting the available data

 

 

It contains a lot of animated explanations of why and how volcanic eruptions occur.
