Figure 2. Epicentres in the West-Bohemia/Vogtland region from the period of 1991–2009. Colour coding high-
lights individual focal zones (1 – Nový Kostel (NK), 2 – Klingenthal, 3 – Kopaniny – Adorf, 4 – Lazy, 5 –
Marktredwitz, 6 – Schöneck, 7 – Plesná) according to Horálek et al. (2000). – Upptakasvæði jarðskjálftahrina
í Vestur Bæheimi og Vogtlandi á árunum 1991–2009. Svarta línan sýnir landamæri Tékklands og Þýskalands.
Figure 1. The West Bohemia/Vogtland earthquake swarm region as a part of the Leipzig-Regensburg seismoactive zone with
the earthquake epicentres (grey dots, red and purple circles) and principal faults (full lines). The N-S striking faults pertain
to the Leipzig-Regensburg fault zone, the main focal zone Nový Kostel (NK) is situated at an intersection of the Eger Rift
(ERG) and Mariánské Láznĕ fault (MLF). Nearby extinct volcanoes Komorní Hu̇rka (KHV) and Z̆elezná Hu̇rka (ZHV)
are denoted by blue stars. The area of a high flux of mantle derived CO2 is situated south-west of NK. The maximum
compression in the region striking 140◦ (S̆vancara et al., 2008) is indicated in the lower left corner. Triangles represent
seismic stations of the WEBNET (green - apex up) and SXNET (dark green - apex down) networks; green-blue, apex down
triangles represent other German stations. Black squares denote towns. The Czech-German border is marked by violet
dashed line. – Upptakasvæði jarðskjálfta í Vestur Bæheimi í Tékklandi og Vogtlandi í Þýskalandi. Rauðir hringir tákna
skjálfta yfir tveimur stigum en gráir hringir minni skjálfta. Flestir skjálftanna hafa upptök á Nový Kostel (NK) svæðinu,
á milli Eger gliðnunarsvæðisins (ERG) og Mariánské Láznĕ (MLF) misgengisins. Þríhyrningar sýna staðsetningu jarð-
skjálftamælistöðva. Útdauðar eldstöðvar eru merktar með bláum stjörnum en borgir með svörtum ferningum. Brotalína
sýnir legu landamæra Tékklands og Þýskalands.
