Earthquake scales (adjusted) in Germany, Europe

As you might have noticed, the earthquakes are increasing here in Germany. Every time I left an “I felt it!” remark to the agencies that investigate earthquakes there are a bunch of descriptions that you’re being asked. However, the comparisons to the current earthquake scale descriptions didn’t really match with what they felt like.

My guess was these earthquake scales are like they are because they mainly happen somewhere else.
And somewhere else they’ve got different houses, different buildings, different building styles, different building materials as well as a different ground structure; so basically it was difficult to compare.

Via juskiserdbeben I found a more “Europeanized” earthquake scale, which makes a lot more sense in this area. With “freundlicher Genehmigung” I’ve translated the European earthquake measurement scale in English:

And yet another earthquake at Darmstadt: M2.6

Although we had a short discussion what it exactly was, I kind of knew it was yet another one and guessed it was around M2.5

Then, on Twitter, the first reactions and discussions, some people nearby didn’t feel it, some did.

Also at work some people were aware of it, some weren’t. Only a few recognized it as an earthquake, and that were also the ones I’d discussed the increase of earthquakes nearby with. Most people didn’t notice, a few remembered they had heard a big bang or a rumble, but didn’t feel it.

After a while the first reports come out:

This time pretty much the same as last times:
A short, 3 second quickly louder becoming low rumble, then the building had a fierce trembling. Chair vibrated along. Other people in same room also noticed but discussed if this was from a construction area nearby.

Interestingly enough, after a discussion with a colleague about the earth being clearly in move these days, I made a little graph of the recent local earthquakes around Darmstadt, then zooming in on the recent ones. The numbers are a bit scary, as well as the graph:

So, when I wrote my blog More earthquakes around Darmstadt, Hesse, Germany to expect? Yes I guess I was assuming right. Not sure if this is going to be a fun ride though.

Equine Plastic Surgery enhancements.

Via the Veterinary Medical News Network:

There has been a startling increase in the number of Arabian Horses becoming addicted to plastic surgery in the last few months.

The increase is mainly driven by the desire to get “likes” on “Facebook Selfies”.
A Survey by the American Academy of Equine Plastic Surgery (AAEPS) found that four out of three equine plastic surgeons reported seeing an increase in requests for facial procedures because horses wanted to look better online.

Corsica day 19 – Perseids Floyd

This morning we both somehow succeeded to wake up at way past 10, so we had to go to the Spar nearby to fetch our breakfast. My mom took my favorite Mousse de Canard au Port and we both bought cards to be sent out. But so many cards were quite tiresome, so I suggested I should just put the names on there and put then in the mailboxes when we were home. My mom didn’t agree on that one though. After I finished breakfast my mom said she would get the bread and drinks ready and I disappeared with the surfboard and rest towards the beach. Not much later my mom pulled me out again for the usual ritual of the “anti sunburn dance” and I could go back again.
My mom came over as well into the sea with bodyboard and flippers and we had a swim together to the other beach. It was not as ‘wavy’ as the days before, but still there were some nice waves. When we got closer to the other beach my mom approached the rocks there and showed how close we could get with bodyboard thanks to the flippers. It’s all a matter of rhythm and doing the right things at the right moment, but you only get there if you do it and practice it.
While my mom swam back the whole way I went over the rocks in front of the hotel and there were some nice discoveries in there, like soft, small sand for instance, not the little stones we got furhter at our beach. We were going back at the same pace and then I jumped into the water again and we both swam towards the little boat which was in the water there. My mom showed me where it was safest to be amongst boats when they are moving or in the water. Then I decided to swim back all the way and after I ate something I was back in the water again for an hour. My mom said I should be back at 18h and reserve a table at the little restaurant again, but I kind of forgot the time again and dove off with my friend for a while longer.
But when she said I could get bread instead as well I was back real quick and I went up to the restaurant to order a table for two with sea view at 19:30. We went back to the camping to pack a bit, clean a bit and then back to the restaurant again. But then I found out that the woman had understood 9:30 so we were 2 hours early. And we didn’t get a place at the beach either. But still it was good enough. After I had a stroll through the whole menu card i decided I did want to get moules a la diane with Pommes Frites and then my mom quickly taught me how to ask for desert of at least the card for desert. When the woman came by she got my order for a Tarte Fine avec Pommes, Caramel et Sauce de Vanille, something I had never tried before. But if you never try something new then you won’t ever get to find out something new either and you will never find out if you like that or not.
The jazz music which was playing I really liked but then the band started to gear and warm up next door at the hotel and that was just not going well together with the music from the restaurant. But they fixed that soon, the band was quiet again after the soundcheck and I could enjoy the jazzmusic again. It got more and more crowded at the restaurant and at one time my mom got up and me too, then the owner of the restaurant said “thank you” as he walked buy guiding 2 new people to our table.
We quickly paid but my mom didn’t want to leave, as there was the perseid shower going on. So we went via the bar down to the beach again and we got to watch the stars. I could not resist though and had to get wet feet. What I didn’t realize was that the waves were a lot higher and I couldn’t really see them well so I got back with wet pants. We then laid down on the rocks with our feet in the sand, being overwhelmed with pretty good music (my mom said it was Dire Straits and Pink Floyd) and I have seen 4 meteroids flying by from the Perseids meteor shower. We also saw 2 satellites, one going west and one going east, and then the moon did rise, it was a very spectacular view how quickly it got up. But also the stars were very nice and very bright and it was fun to see that e.g. Orion had completely disappeared under the horizon and Scorpius was just in front of us over Belvedere Campomoro at the other side of the bay.
When we got back up to the bar again the music was playing nice and we decided to listen to a few songs. I really liked the drummer who was a woman and my mom said she was completely lost in the moment in the music and it seemed like she hit everything at the right moment. And she could play really fast as well. When we went my mom said I should walk up to her and say thank you or similar but I was too shy. But after a while I did dare and I walked up and said that she played really good, which she actually did. My mom said she was shining from the moment I said that. Maybe one day I should learn to play drums as well but my mom doesn’t think it’s a very good idea though. Not much later after I hit the pillow I was asleep. We were still in doubt though to either drive back or go and stay a few days longer near the sea.

Corsica day 18 – Deutschland Eck

This morning, well, morning? I slept till past 10 AM and then all of a sudden woke up and needed a sprint to the toilet buildings. What my mom taught me about drinking at least 1.5L per day has a disadvantage and it’s not a good thing to wake up that early to do what nature asks you. Anyway, when I got back at the tent my mom sent me back to clean up some dishes from last night because breakfast was waiting for me since an hour. I totally missed when the Boulanger came by?
Not much later we had our breakfast and when we finished our default Pain au Chocolat and Croissants with Lait Sucre the camp owner walked by with new guests and they were all german! So I went crazy and said that we had “Deutschland Eck” again, we were surrounded by Germans! And hey all had a Muenchener licenseplate. My mom found out later that one half of them was from Hessen these days as well and the M licenseplate was just a rental, and their son was studying in Darmstadt as well.
But then my mom said I had to fullfill my daily duties and she would do the washing. So by the time I was ready sorting out my clothes that needed to be done quite a pile was waiting. But that didn’t matter, I only had to do the dishes and such, so when I came back my mom had just finished tidying up and I was ready to go to the beach. So I went there all by myself and this time the waves were just great, I spent a long while having fun there. I also met another german boy with red hair who came her every year and we both had fun going crazy in the waves. After a while my mom came by and she said she would go shopping. We needed something for tonight to eat but she couldn’t see any more pasta, so she wanted to look for something else. I said I wanted to eat Pasta though and if that wasn’t available I wanted to eat bread with Mousse de Canard. So when my mom came back after a while I got pasta and mousse de canard on bread. Shortly after I disappeared in the waves again which were even bigger than before and I really really liked it. My mom went swimming with my bodyboard and then had a quick walk to take some pictures. She came back saying that the Corsica Ferries seemed to be at the harbor of Propriano and also the Moby, next to it. Anad also a catamaran had fallen over due to the wind and the people had problems to get it back on it’s feet again, but they succeeded after a while.
Not long after, at least it felt like that, she came to pick me up and despite me protesting I realied that after 6 hours of non-stop swimming it might be a good idea to get a shower and eat some. So after my mom dragged me from my book again I ate some couscous and then after a while I disappeared in my bed with my book, ready to go for a good sleep. Tomorrow is packing day, because it was my idea to pack our stuff together on the day before we had to go and then when we had to go we only have to pack our tent and contents, and that’s it. We well leave the canu here though and that’s something I really don’t like. But my mom keeps on saying we’ve got a boat at home which is a lot more suitable and bigger as well. But I still like the canu. Maybe I can still sell it for eu 10,-.
