The measured P-wave velocity and fracture density of this mudstone layer suggest that it could amplify seismic waves, increasing the risk of damage during earthquakes159. Fractured mudstone is particularly vulnerable to deformation during seismic events, which could lead to surface ruptures160. Since ...
we focus on the exhumed damage zones of strike-slip faults dissecting the south-western part of the Mesozoic cover of the Late Palaeozoic Holy Cross Mountains Fold Belt (HCFB) in Poland (Fig.1a–c) (e.g. Czarnocki1938; Mastella and Konon2002). We study the damage zones having...
Between 4 September 2010 and 23 December 2011, Christchurch was struck by earthquakes and aftershocks up to moment magnitude 7.1, referred to as the Canterbury Earthquake Sequence (CES). The CES killed 185 people and caused extensive damage throughout Christchurch estimated at ~NZ$40 B (~US$31...
10 Simplified time–space diagram of small-scale sequence 13 and its interpreted 5 elementary sequences, outlining correlatable and non-correlatable intervals in the studied sections. SB: sequence boundary; MFS: maximum-flooding surface; Ru: Rusel; Ma: March- airuz; SC: St. Claude; La: La...
Deep hydrothermal circulation has been elaborated by microearthquakes and geochemical data (Tao et al., 2020). The development of abundant polymetallic sulfides and silicified breccia has been discovered through geophysical surveys and deep-sea sampling (Tao et al., 2013). The active Longqi ...
Numerous factors can influence the occurrence, type and spatial distribution of sediment gravity flows, including the structural activity, submarine slope gradient, paleoclimatic conditions, earthquakes and volcanism (Mutti and Normark, 1987, 1991; Piper and Normark, 2009; Pochat and Van Den Driessche...
Earthquake - Shallow, Intermediate, Deep Foci: Most parts of the world experience at least occasional shallow earthquakes—those that originate within 60 km (40 miles) of the Earth’s outer surface. In fact, the great majority of earthquake foci are shal
The shallow underground explosive source localization has been studied in the fields of natural earthquakes and microearthquakes. The traditional localization method mainly depends on travel time inversion, and the key link is to identify and pick up accurate travel time information. However, because of...
