Dear colleagues,
It is our pleasure to invite you to contribute to the session S28 entitled "Applications and developments in ambient noise seismology" to be held during the 36th General Assembly of the European Seismological Commission in Valletta, Malta, during 2-7 September 2018 (http://www.escmalta2018.eu/page/home).
This session welcomes contributions focused on ambient noise seismology.
Abstract submission will run until 31-March-2018.
Please do not hesitate to contact us regarding the suitability of your work for this session. We look forward to receiving your submissions and seeing you in Malta in September!
Best wishes,

Session description: S28 - Applications and developments in ambient noise seismology
In the absence of earthquakes and other strong seismic signals, the Earth surface is not static but constantly vibrating due to many continuous noise sources such as ocean waves, storms and anthropic activities, generating the so-called ambient seismic noise. Ambient seismic noise has proven to be a valuable tool for imaging the earth at different scales via surface and body wave tomographies. The continuity and reproducibility of ambient noise correlations, make them an excellent candidate for the monitoring of crustal properties, which has found applications ranging from volcano monitoring, dynamic recovery processes of earthquakes to civil engineering. The energy source for most applications is the microseism. The microseism sources are closely related to ocean wave energy coupling with the Earth's motion and have today broad applications, among which the investigation on atmosphere-hydrosphere-cryosphere-solid earth interactions, to make also inferences on climate changes. In this session, we welcome contributions focused on ambient noise seismology. We invite contributions concerning multi-scale applications of seismic noise interferometry, such as imaging structure and monitoring subsurface changes. We are also enthusiastic to receive studies on the sources of ambient seismic noise (i.e. microseisms, hum, microbaroms), their generation processes, and their applications on the investigation of atmosphere-hydrosphere-cryosphere-solid earth interactions. This extends also to methodological and more theoretical approaches (i.e. role of scattering, alternative processing techniques).
Hello fellow MSNoise users,
I have in my hands a case of an erupted mud volcano. The event took
place between February 12th and February 13th and got attention very
quickly from media and people in Trinidad & Tobago. I don't know if any
of you have any experience working with MSNoise and mud volcanoes. A
high quality drone footage you can find here
<https://www.facebook.com/topshotaerialservices/videos/984076211740133/>,
story on the media here
<http://newsday.co.tt/2018/02/17/mud-volcano-goes-quiet/>.
I am thinking of setting up a project around it, but since there is not
much information as to what to expect, I seek advice from all of you.
According to geologists here, the whole thing has gone dormant on the
surface. There is no volcanic activity, hard rock or magma movement
underneath. Some studies propose a disturbance down to 3 or 6 Km of mud
and gas intruding the younger harder formations.
Questions in my mind are both of practical and scientific perspective:
- Since we don't expect any conventional seismic/volcanic activity, will
the network record anything of use?
- I have in my hands 5 to 6 Guralp 5TDE (accelerometers). Will they be
able to record noise down to the frequencies of interest?
- Related to the previous, what would be the optimum aperture to deploy
the sensors (taking into account we need to extract information down to
3-6 Km)?
Any ideas, suggestions or advice are appreciated.
Ilias

Dear Sirs
I'd like to attend a workshop on MSNoise (a course for beginners). I saw
that you made one in August. Are you planning a new one for this year? If
yes, could you let me know when and where because I've to plan my money
request for this year before the end of Jenuary.
Thank you
Best Regards
Anna

Greetings,
Just installed msnoise 1.5 with python 3.6 through anaconda on a CentOS 7
machine.
After populating the stations table with all the stations I have got in my
sc3 database
I have 1418 entries en the stations table.
msnoise plot station_map crashes:
[sysop@skjalfti04 msnoise]$ msnoise plot station_map

Is there a fix or am I not allowed to have the whole station database in
there?
