| description | <p>Among the multitude of magnitude scales developed to measure the size of an earthquake,
the surface wave magnitude <span class="inline-formula"><i>M</i><sub>s</sub></span> is the only magnitude type that can be computed
since the dawn of modern observational seismology (beginning of the 20th century)
for most shallow earthquakes worldwide.
This is possible thanks to the work of station operators, analysts and researchers
that performed measurements of surface wave amplitudes and periods on analogue instruments
well before the development of recent digital seismological practice.
As a result of a monumental undertaking to digitize such pre-1971 measurements from printed bulletins
and integrate them in parametric data form into the database of the International Seismological Centre
(ISC, <span class="uri">http://www.isc.ac.uk</span>, last access: August 2021), we are able to recompute <span class="inline-formula"><i>M</i><sub>s</sub></span> using a large set of stations and
obtain it for the first time for several hundred earthquakes.
We summarize the work started at the ISC in 2010 which aims to provide the seismological
and broader geoscience community with a revised <span class="inline-formula"><i>M</i><sub>s</sub></span> dataset
(i.e., catalogue as well as the underlying station data) starting from December 1904
up to the last complete year reviewed by the ISC (currently 2018).
This <span class="inline-formula"><i>M</i><sub>s</sub></span> dataset is available at the ISC Dataset Repository
at <a href="https://doi.org/10.31905/0N4HOS2D">https://doi.org/10.31905/0N4HOS2D</a> <span class="cit" id="xref_paren.1">(<a href="#bib1.bibx34">International Seismological Centre</a>, <a href="#bib1.bibx34">2021</a><a href="#bib1.bibx34">d</a>)</span>.</p> |
