Dear All,
this is to advertise the next meeting of the Climate Journal Club.
We will meet on Monday 2nd of May in room U1-10 at 11:30 and Emanuele Bozzi will talk about "Thunder- and earthquake-induced ground motions recorded by telecommunication optic fibers".
Here the abstract of the talk:
Distributed Acoustic sensing (DAS) is an innovative method which exploits optical
fibers as continuous sensors for longitudinal strain/strain-rate measurements. Recently
there has been a growing interest in using DAS on telecommunication optical fibers,
already installed and currently not-in-use (dark fibers). These cables constitute
potential “dense network” to monitor environmental phenomena affecting inhabited
centers. Furthermore, obtaining an area/time coverage comparable to DAS with
standard seismic sensors might be unfeasible in such urban situations. Here, some
case-studies are presented, illustrating DAS applications on meteorological and
earthquake events monitoring in Pennsylvania, USA. DAS can provide dense ground
motion measurements of 1) storm-induced thunderquakes, 2) teleseismic events and
3) local natural/induced seismicity.
The paper by Zhan, 2020 is suggested as an introduction to the DAS technique. The
paper by Zhu and Stensrud (2019) is proposed as a reading for the meeting, while for
other DAS applications on the same optical fiber the paper by Zhu et al., (2021) is
suggested.
A friendly reminder will be sent in the next days.
Looking forward to meeting you all,
the CJC team
