Earthquake with the size of Mw5.3 in Greece, Dodecanese Islands this morning

Early this morning at 04:24 UTC there was an earthquake with the size of Mw5.3 this morning in Greece, Dodecanese Islands according to EMSC. The depth is estimated around 10 km. According to EMSC this earthquake was felt on nearby Islands. But it was followed with more the dozen or so aftershocks. The largest ones had the size of ML4.1, the largest aftershocks have also been felt on nearby Islands. But the epicenter of this earthquakes is out in the ocean. A good distance from next populated area. Aftershock activity is currently ongoing in this area.

Earthquakes of this size are common in this area of Greece. But in this area of Greece has an active subduction zone. As can be clearly seen on this picture here.

For this reason, this area is highly active in both earthquakes and volcanoes.

Special on glasses and GSM repeater

Because I have to buy new glasses. I have to delay buying GSM repeater for my mom and dad. As my income does not allow for me buying both. But the cost of each is around 2000 DKK (offers and discounts depending on the glasses). A money that I cannot afford to spend all at once now. So I am just going to collect for the GSM repeater later in the year after I have moved to Denmark. As glasses have nr 1 priority for me. Since I am close to being blind without glasses. That is one reason why I hate having this small income as I do today. It is my hope that I can change it in next few months (12 to 24 months). At least I am going to try to do so.

Those how have already supported me for the GSM repeater. Thanks for the support. I however have to use it buy new glasses when I go to Denmark next month to apply for an apartment.

Minor earthquake swarm in El Hierro volcano

After the eruption ended in El Hierro volcano it seems that minor magma dike intrusions have been taking place. This magma intrusions so far appears to be deep and not big. Given the depth and the size of the earthquakes that are currently taking place. This also suggests that new magma continues to flow into El Hierro volcano. But that flow might be at slower rate then it was early in the year 2011 before the eruption started. The largest earthquake in this swarm had the size ML2.8 with the depth of 12 km. Based on automatic data.

It is hard to know for sure what this means for future eruption events. Before the earthquake swarm today there was an small eruption somewhere in El Hierro volcano. It can be seen by the harmonic tremor levels. But this event was small, a lot smaller then earlier events. All that can be done is to wait and see what happens next in El Hierro volcano.
