  1. In these days, it's very hot in Sicily!

    Today, I registered a max of +36°C (670 mals) and some areas near Catania have touched +41°C! ;)

    It's very difficult to go out on the street! :o

    Fortunately, tomorrow temperature will get down!

    Ps: no rain since one month!

  2. Good evening everyone! :nea:

    Today, It's raining so I've taken two photos a few minutes ago. As you can see there is a beautiful rainbow.

    Little town of second picture is Trecastagni that meaning Three Chestnuts. :)

    Trecastagni is just 2 Kilometres away from Pedara (where I live), and 15 Kms from Catania.post-7691-1207329469_thumb.jpg

    Ps: currently, temperature is +7°C. :)

  3. Hi everyone! :(

    Today is a beautiful day at home, especially in the afternoon. So I decided to take a photo of my little town Pedara (near Catania).

    You can see the church tower and Mount Troina near. Mount Troina is an ancient and little volcanic cone off by now! It belongs to Etna volcanic system.

    Finally, you can see the Catania's Gulf and the Ionian Sea. :)

    Ps: sorry for my English! :(

  4. Hi - yes I am indeed. I have an undergraduate degree in Geophysics and a masters degree in Exploration Geophysics. I then worked for 6 years as an exploration seismologist for an oil & gas exploration contractor before returning to do the PhD - which I need to finish up fast as I've accepted a job as an interpretation Geophysicist with another oil & gas exploration contractor - though this is more to do with potential fields (gravity and magnetics).

    Send me a personal message if you want any advice (career wise or anything else) and best of luck!

    Thanks for info! :huh:

    If I'll need you, I send you a personal message! :)

  5. If anyone in interested into a more thorough explanation of what is contained there then please ask. As will be the same case for today's event, once picked the phase data is organised according to station and distance/time from the header downwards. Only in the case of severe anisotropy in the crust would this differ. Most of the phases relate to P-arrivals, with usually about 33% S-arrivals. The others relate to the peak to peak amplitude picked on the waveforms to determine the magnitude of the event. I have kept the amplitudes as determined at the time, but the back-catelogue of earthquakes (f.e the Dudley event) has been relocated with a 3-D model of seismic P- and S- velocity. The models used to provide the locations of say, todays event are 1-D models, that may be rather inaccurate. This is particularly true for eastern and southern England where there is little constraint from wide angle refraction profiles, because simply none have ever been shot in this area. Most of the 1-D models used to locate events in the UK are derived from refraction profiles shot in the 1970s (LISPB, Bamford et al.).

    So there is still much work to be done. The largest errors in earthquake location are associated with depth. You can alter the depth alot but not affect the travel-time much, but change its spatial position in x and y it will.

    Your posts are very interesting and precise! ;)

    Are you a geophysical researcher?

    I'm a student of geophysics at Catania's University and I hope to graduate this year. :)

    Ps: sorry, but I don't speak English very well yet! :(

  6. Currently, temperature is +4.5°C and sky is overcast partially.

    After about 15 days characterized by mild climate, already tomorrow, we expect a cold perturbation from Balcani!

    I hope to look the first snow of the season! :huh:

  7. Very interesting topic! :)

    There was a great activity on Etna this night. Particularly, the southeast crater produced lava fountains very high (a few hundred meters) with emission of volcanic ash. A lava flow has now reached the Bove's Valley, but there is no danger for homes. The tremor amplitude was very high but now the activity ended, it lasted only a few hours as in September. :cold:
