Day: October 3, 2013

Donation note: I still need donations for October. I currently have no money for anything and that is rather bad. This bad situation that I am having is going to last for several months according to an excel document that I have set-up to figure out my total debt repayment. I can repay my debt (or buy replacement hardware if anything fails), but not buy food at the same time. The exchange rate of ISK to DKK is also bad at the moment. I hope for improvement but that won’t happen for next several months at least.

Activity in Tjörnes Fracture Zone continues as it has been doing for the past week. There is not a lot of other activity taking place in Iceland at the moment. The largest earthquake today (03-October-2013) had the magnitude of 3.5, a second earthquake with the magnitude of 3.1 also took place in TFZ today. Depth of this earthquake swarm remains the same, around 5 to 15 km at current time.

Today (03-October-2013) there were fewer earthquakes in this swarm than yesterday. The drop is currently around half of less activity than yesterday. I am not sure why this is as currently the earthquake swarm is ongoing. Even if there are fewer earthquakes taking place. This might just be a short time drop in earthquake activity, or this might signal an end of this earthquake swarm. Currently it’s too early to know for sure. The only thing that can be done is to wait and see what happens next in this earthquake swarm.

So far there are no signs of any magma having reached the surface, if that is the reason for this earthquake swarm in this area of Tjörnes Fracture Zone.

Donation note: I still need donations to survive this month as any other months while I am just on social welfare from Iceland as I have explained here. This month I just have around 24 DKK (3.21€) for food this month after paying all the bills and my debt. I have already got some donation, but they just allow me to buy food for about one and half week if I am smart. Thanks for the help.

The earthquake swarm on Tjörnes Fracture Zone continues. The earthquakes are getting stronger, with the largest one today having the magnitude 3.8 (automatic results) and five other earthquakes with the magnitude 3.0 to 3.2. Currently the depth is around the same, it remains at 5 to 15 km and at the moment it doesn’t seems to be changing. Rate of earthquakes is around the same today (02-October-2013) as it was yesterday (01-October-2013), with no major changes in earthquake rate from what I can see currently taken place.

All earthquakes above magnitude 3.0 have been felt in Siglufjöður and Ólafsfjörður towns and other populated areas that are close to this earthquake swarm. There are no signs of this earthquake swarm slowing down as is. It still has not been confirmed if this earthquake activity is connected to magma injection at depth, or if this is just normal tectonic earthquake activity in this area. It’s going to remain difficult to confirm this idea until an eruption starts in this area and that simply might just not happen at all. The largest earthquakes appear on my webicorders website here, on the geophone station named Böðvarshólar.
