[MSNoise] 🌋MSNoise and CovSeisNet Workshop/Hackathon on 9 December 2023 in San Francisco, USA 🐍

*Dear colleagues,*

*

We are excited to announce an upcoming workshop/*hackathon taking place 
on Saturday 9 December in San Francisco*. This event will feature an 
exploration of two Python packages - *MSNoise and CovSeisNet*, offering 
the chance for hands-on learning and applications in monitoring seismic 
activity and analysing ambient seismic waves.


*MSNoise *is a well-known Python package specifically designed for 
analysing the ambient seismic wavefield and extracting information from 
“the noise”. It allows for the calculation and analysis of seismic noise 
correlations, also known as ambient noise seismic interferometry. The 
latest version also includes possibilities to compute PSDs and to 
investigate them interactively.


*CovSeisNet *is a Python-based package providing tools for seismic 
network-based processing. The central analyzed mathematical construction 
is the network covariance matrix (inverse Fourier transform of the 
cross-correlation matrix). The core signal detection algorithms are 
based on the analysis of the eigenvalues of this matrix. Eigenvector 
decomposition provides a basis for a blind source separation and the 
first eigenvector is used to locate some discrete (e.g. earthquake) or 
continuous (e.g. tremor) sources.


For those unfamiliar, a hackathon is an event, usually lasting a few 
days, where several people meet to engage in collaborative computer 
programming. It's a chance to innovate, to learn, to collaborate, and to 
create new code, solutions, and visualisations. In our case, two 
packages will be used during a single-day event *(9.00-17.00)*!


To make this event more interactive and indeed, intriguing, we will be 
providing *seismic data from Iceland* before the hackathon. Participants 
are encouraged to utilise MSNoise and CovSeisNet to analyze this data as 
a form of "homework". We will set up a Mattermost platform (free, 
self-hosted slack-equivalent) for the workshop participants to interact. 
On the day of the workshop, we will compare and discuss the results, 
highlighting different techniques and approaches.


Furthermore, during the hackathon, we will work collaboratively to 
create new solutions and visualisations using these packages. To fully 
take advantage of this collaborative coding experience, participants 
must have a solid foundation in Python programming.


If you are interested in joining us, *we ask you to express your 
interest* by filling out our Google form via the following link:

Should you have any queries or require further information regarding the 
hackathon, please feel free to reach out, w*e look forward to seeing you 
on 9 December in San Francisco.*
