[MSNoise] Pre-IAVCEI 2017 MSNoise workshop

[Thomas Lecocq]

*Pre-IAVCEI 2017 MSNoise workshop*

We are pleased to announce a *2-day MSNoise workshop* on*Saturday 12 and 
Sunday 13  August 2017*, the weekend before IAVCEI 2017 in Portland!

The aim of this workshop is to demonstrate the powers and limitations of 
using ambient seismic noise for seismo-volcanological studies using 
continuous data, for example using ambient seismic noise 
cross-correlation for computing dv/v, surface wave tomography or 
microseismic activity tracking. The MSNoise package will be introduced 
and then used by participants on provided demo data (from Piton de la 
Fournaise volcano). New developments to MSNoise will be presented too: 
an easier configuration interface, an improved pluggability and the 
demonstration of external plugins currently in development (e.g. Quality 
Control, Power Spectral Density, TOMO or SARA). In the framework of this 
conference, we will particularly introduce the Seismic Amplitude Ratio 
Analysis (SARA) that was specifically designed to track magma migration 
at volcanoes using seismic data (e.g., Taisne et al., 2011).

During the first session, we will make sure everyone has the right 
software and provide a refresher course on Python/ObsPy. The second 
session will contain review presentations related to “the seismic 
interferometry” followed by a practical using MSNoise. The last session 
will specifically cover the Seimic Amplitude Ratio location technique 
and the Ambient noise-based Tomography, before a MSNoise hacking session.

*Day 1:*

  * 09.30 – 10.00: Welcome
  * 10.00 – 11.00: Installation “party”
  * 11.00 – 12.30: Refresher course on Python/ObsPy (version 1.0 & new
    features)
  * 12.30 – 13.30: Lunch (not provided)
  * 13.30 – 15.30: Introduction on Noise – What is Noise? How do we use
    it? Cross-Correlation? dv/v? – MSNoise general introduction
  * 15.30 – 18.00: MSNoise practical

*Day 2:*

  * 09.30 – 10.00: Welcome
  * 10.00 – 12.00: Noise-based studies (SARA, TOMO)
  * 13.30 – 16.00: Advanced MSNoise Practical (Jupyter notebooks, API, etc)

Because of high organisational costs, we can’t afford to organise this 
workshop for free. We have fixed the fee to 230 USD per person. Payments 
will be done online directly while registering for the IAVCEI meeting.

To ensure the quality of the experience for everyone, we will not accept 
more than 30 participants. Each participant is required to have a 
sufficiently decent (and fast!) laptop with software requirements 
installed beforehand (instructions will follow). Participants are not 
expected to be Python experts at all, but having a little experience in 
programming will be useful.

*Information on MSNoise:* MSNoise is the first complete software package 
for extracting signal from noise. MSNoise is a fully-integrated solution 
that automatically scans data archives and determines which jobs need to 
be done whenever the scheduled task is executed (http://www.msnoise.org).

*Registration:* Via the IAVCEI meeting registration page.
