In
Mainz
(intensity V) “
Ist die Erschutterung des Erdbebens auch zu Maynz
verspuhret worden
[
]
dass einige Sachen in Kirchen und Hausern davon uber
einen Hauffen gefallen
” [“The effects of the earthquake were also felt in Mainz
[
...
] to such an extent that some objects in homes and churches fell to the ground in
a heap”].
In
Frankfurt/a.M
. (intensity V) “
Ist das Erdbeben auch zu Franckfurth und
in der Gegend observiret worden welches denn als etwas ungewohnliches einen
grossen Schreck und Entsetzen unter den Einwohnern verursachet, indem die Hauser
selbigen Orthen dermassen commoviret wurden das die Tinten-Fasser Glaser und
andere Sachen von den Tischen
[
...
]
herunter fielen
” [“The earthquake was noticed
in Frankfurt and the surrounding area where, as something totally unusual, it caused
great shock and horror among the inhabitants; as the homes in these places were so
shaken that ink pots, glasses and other things fell down from the tables”].
In
Trier
(intensity VI) “
Eben auff die Zeit und Stunde ist solches auch in Trier
und an dem Mosel-Strohme sehr hart und zwey mahl nacheinander verspuhret wor-
den also dass kein Mensch daselbst wie alter auch immer gewesen dergleichen er-
lebet hatte. Es waren unterschiedene Giebel und Schorsteine eingefallen und hatten
einige Hauser und Gebaue Risse davon in den Mauren bekommen welches unter den
Leuten eine grosse Consternation erwecket
” [“At exactly the same time and hour the
same thing was felt in Trier and at the Mosel river - a very violent shock, one after
another that none had ever experienced anywhere else before. Various gables and
chimneys fell and some houses and buildings had great cracks in their walls which
caused great consternation among the people”].
In
Koln
(intensity VI) “dieses Erdbeben
...
wodurch uber 50 Schorsteine die
man wurcklich gesehen und durch dero Fall viele Dacher und niedrige Gebaue
versehret und beschadiget worden. Es haben sich in wenigen Minuten die Hauser
etliche mahl hin und wieder gleichsam Creutzweise und so gar auch die Glocken
auff dem Thurmen beweget wodurch solch geprassel entstanden dass sich die Leute
eiligst und in grosser Confusion auff die Strassen retiriret, um ihr Leben von den
besorglichen Ruinen der Hauser zu salviren” [“This earthquake
...
. whereby 50
chimneys were seen to fall and harm and damage many roofs and low buildings. In
a matter of moments the houses moved this way and that and even the bells in the
towers moved in such a way that the din they occasioned caused the people to rush
out into the streets in great confusion in order to save their own lives from the ruins
of their homes”].
The 1692 earthquake macroseismic map (Fig. 5) is instructive by two aspects.
First, it is clear that very few notices exist in localities where intensity is less
than V. Thus, it is difficult to evaluate correctly the felt area of the event and
to deduce its magnitude from this. Secondly, the isoseismals of intensities V and
VI are not concentric, but have a more elongated shape to the west-northwest.
Recent investigations (Nguyen et al., 2004) showed that site effects due to the
Meso-Cainozoıc cover sediments onto the London-Brabant Massif could be re-
sponsible for the amplification of earthquake strong ground motions. This prob-
lem has not been considered in the present study but should be included in future
investigations.
