There have not been great changes in El Hierro volcano. Currently no eruption has taken place. There are also no signs of magma movement on tremor plots on seismometers stations that are located on El Hierro Island. The dike intrusion in El Hierro volcano is continues, but at slower rate then before. But that it is continuing means there is continued risk of an eruption where the earthquakes are currently taking place. Currently the rate of earthquake is around 3 to 8 earthquakes during the hour. Most of the earthquakes are around ML1.5 to 3.4 in magnitude. Please note that I am missing all earthquakes with the magnitude of ML0.0 and up to ML1.5. So there might well be a lot more earthquakes taking place in El Hierro volcano then I am seeing on IGN web page.

Last 36 hours of earthquakes in El Hierro volcano. It shows clearly where magma has pushed it self into the crust. Creating inflation and earthquakes. The spikes are earthquakes in most cases. Copyright of this picture belongs to IGN.
Past 7 months of activity in El Hierro volcano. This map shows well how magma has slowly been injecting it self into El Hierro volcano during the past few months. Some of the earthquakes there are also just tectonic earthquakes, due to stress changes that injection of magma creates in the crust. The spikes are earthquakes in most cases.

According to official reports. The inflation of El Hierro volcano is around 10 cm according to official reports, or around that. I am having hard time finding the official news reports on the inflation in El Hierro volcano at current time. For the moment, the current situation is stable for the moment. But when that might change is impossible to know for sure. But there is magma inside El Hierro volcano, so there is an increased risk of some of that magma finding it’s way to the surface and erupting. But that might be out in the ocean as last time, or on land. It is impossible to know that for sure until an eruption starts. For the moment, nothing can be done the to watch and monitor the current situation in El Hierro volcano.

It seems that Icelandic volcanoes and fault zones are on some type of summer vacation for the moment. So I am covering other things while the quiet period in Iceland is currently ongoing.

In total 51 <1.5 between 01 July and 08 July @ 10:30 UTC so not that many really.
Earthquake Catalog
Now, in exchange where do you get those maps? I can’t find them on the site.
Thanks for the information. You can find the map of El Hierro volcano here, along with other useful information.

Many thanks! Big rush of quakes going on right now. 19 over 2.5 since 09:30
There is new magma injection ongoing. I am monitoring and watching how it goes. I am going to write about it tomorrow.
This seems to go in spasms. A rush of quakes and then quiet. Is that normal?
The activity depends on magma injection. So low magma inflow, small activity. High magma inflow, high activity. So I guess this is normal. But there might be more factors at work here that I do not see.
It is hard to know for sure. Since the magma is changing the crust stress levels in the El Hierro volcano. That also creates earthquakes.
