6. Future Accomplishments
In our study, we focused on utilizing the HYSPLIT modelling system with
GDAS meteorological data, volcanic ash cloud composite, ash cloud
trajectory frequency, and ash particle positions, which are discussed in
Section 4 of the paper. Additionally, we generated event time
seismograms using PyWEED, as shown in Figure 3.
Regarding seismic activity in the Czech Republic, there is potential for
implementing a machine learning-based sensing system using optical
fibres as seismic sensors. In the western part of the country,
particularly in the Nový Kostel region, there is a history of frequent
earthquakes with magnitudes below 4 occurring throughout the year. This
presents an opportunity for deploying new fibre sensing methods in our
country, as we have access to optical fibre lines that are commonly
shared for research activities. Dedicated parts of the spectrum are
being tested for various research transmissions, including sensing, QKD
(Quantum Key Distribution), and Precise Time and Frequency transfers,
leaving room for cost-efficient solutions for future research
endeavours.
Collaboration with well-established and recognized volcano regions,
which possess comprehensive sensing data, could provide valuable
insights and more precise methods for volcanology. Optical fibre sensing
methods offer the potential for acquiring essential data on gas content
and composition in seismic activity regions worldwide.
The CESNET2 network in the Czech Republic already applies advanced
applications for sensing in the Temelín nuclear power plant,
specifically for containment stability measurements. This involves
ultra-stable frequency transfers between the National Metrology
Institution and the containment sensors. While the project primarily
focuses on the stability of the containment itself, it also considers
seismic events, including earthquakes.
To compare the situation during the eruption events of the HTHH
submarine volcano, we examined seismic activity on the other side of the
Earth, specifically in central Europe, where our locality is situated.
Figure 9 demonstrates a seismograph recording an earthquake activity
with a magnitude of 2.8 at 02:54:47 UTC on January 15th, 2022, near the
Aschach area, northwest of Linz. This earthquake activity was also
monitored for the safety of the nearby Temelín nuclear power plant.
Although these seismic activities generally have ”low” magnitudes, they
tend to be long-lasting and occur throughout the year. CESNET, as the
Czech NREN (National Research and Education Network) provider, actively
engages with advanced technologies to achieve more precise measurements
and is open to further collaboration within the field.
