Here is the update for El Hierro earthquakes until the 28th.
There is some novelty !
You will notice that the “active” earthquake is in red. The dot in that case is not proportional to earthquake magnitude.
For the older earthquakes size is proportional to magnitude.
One can see 3 different events :
- from the 1st to the 15th, earthquakes are localized in a shallow zone around 10 km depth
- between the 15th and 21st earthquakes move down to a zone around 20 km and their magnitude is somewhat higher
- since the 21st earthquakes are present in both zones and seem to move between them.
