The seismometers that British Geological Survey did pay for to be installed around Eyjafjallajökull volcano and Mýrdalsjökull (Katla volcano) have been integrated into the Icelandic Met Office SIL Seismometer Network. They have at least been marked into the Icelandic Met Office earthquake web page.

The new stations are marked with a triangles on the map. The older SIL stations can be found at Icelandic Met Office tremor web page. Currently the new SIL stations are not on Icelandic Met Office Tremor web page yet.
What this means for earthquake recording in this area is that Icelandic Met Office is now able to detect smaller earthquakes. Location of earthquakes is also going to improve a great deal, so automatic location of earthquakes is going to improve a great deal in this area. This means that more earthquakes are going to be visible on Icelandic Met Office maps then before.
