“…11 falls inside the triggering threshold for mud and magmatic volcanoes proposed by Delle Donne et al (2010) and well outside the threshold proposed by Manga et al (2009). Delle Donne et al (2010 use a satellite-derived heat flux inventory for global volcanism to identify earthquake-induced thermal anomalies at active volcanic and mud systems.…”

“…In addition to this study, we measured and investigated other instances of triggered activity (i.e. Lupi et al 2013;Farias et al 2014) falling outside the threshold proposed by Manga et al (2009) and in agreement with Delle Donne et al (2010). Our approach and findings best fit the triggering threshold proposed by Delle Donne et al (2010).…”

“…Delle Donne et al (2010 use a satellite-derived heat flux inventory for global volcanism to identify earthquake-induced thermal anomalies at active volcanic and mud systems. Manga et al (2009) propose a large database derived from peer-reviewed literature, eyewitness observations and historical records. The most prominent difference between these two studies (and hence the triggering thresholds) resides in the choice of Delle Donne et al (2010) to include measured processes that may not be directly observed at the surface.…”

S U M M A R YMud volcanoes are geological systems often characterized by elevated fluid pressures at depth deviating from hydrostatic conditions. This near-critical state makes mud volcanoes particularly sensitive to external forcing induced by natural or man-made perturbations. We used the Nirano mud volcanic field as a natural laboratory to test pre-and post-seismic effects generated by distant earthquakes. We first characterized the subsurface structure of the Nirano mud volcanic field with a geoelectrical study. Next, we deployed a broad-band seismic station in the area to understand the typical seismic signal generated by the mud volcano. Seismic records show a background noise below 2 s, sometimes interrupted by pulses of drumbeatlike high-frequency signals lasting from several minutes to hours. To date this is the first observation of drumbeat signal observed in mud volcanoes.In 2013 June we recorded a M4.7 earthquake, that occurred approximately 60 km far from our seismic station. According to empirical estimations the Nirano mud volcanic field should not have been affected by the M4.7 earthquake. Yet, before the seismic event we recorded an increasing amplitude of the signal in the 10-20 Hz frequency band. The signal emerged approximately two hours before the earthquake and lasted for about three hours. Our statistical analysis suggests the presence of a possible precursory signal about 10 min before the earthquake.

“…For developing a comprehensive model involving earthquake and volcanic hazard in this region, Mishra et al (2007) used the local seismic network and studied a large number of aftershocks of the 2004 Sumatra-Andaman earthquake and looked into some of its seismotectonic implications. They inferred that the Baratang mud volcano (Mishra et al, 2007;Manga et al, 2009) region is mainly associated with a thrust faulting mechanism at depths of 0-30 km suggesting a high compressive force beneath, while the region of Barren and Narcondum volcanoes exhibit dominantly normal faulting due to tensional forces that suggest brittle failure in the weakened crust (Mishra et al, 2007). The sequence of earthquakes north of Diglipur comprising six events (Table 3), starting from the main event of M w = 7.5 on 10 August 2009 and tapering off to a small earthquake of M w = 4.5 on 2 February 2011 (hereafter referred as Diglipur earthquakes), indicates the seismic potentiality of this region after the 26 December 2004 Sumatra earthquake.…”

Abstract. Throughout the world, the tsunami generation potential of some large under-sea earthquakes significantly contributes to regional seismic hazard, which gives rise to significant risk in the near-shore provinces where human settlements are in sizeable population, often referred to as coastal seismic risk. In this context, we show from the pertinent GPS data that the transient stresses generated by the viscoelastic relaxation process taking place in the mantle is capable of rupturing major faults by stress transfer from the mantle through the lower crust including triggering additional rupture on the other major faults. We also infer that postseismic relaxation at relatively large depths can push some of the fault segments to reactivation causing failure sequences. As an illustration to these effects, we consider in detail the earthquake sequence comprising six events, starting from the main event of M w = 7.

[1] The origin of muddy sand and gas in muddy sand sediments in the Horonobe area of northern Hokkaido, Japan, was investigated by analyzing the mineralogical and chemical compositions of the sediments and the chemical/isotopic compositions of the gas. X-ray fluorescence and X-ray diffraction analyses indicate that chemically, the muddy sand is derived from a mixing of components from the Hakobuchi and overlying formations, and that the characteristic mineral of the muddy sand is heulandite, which, in the study area, has been detected only in the Hakobuchi Formation. These results suggest that the sediments ascended from depths of at least 2200-2400 m. The d 13 C CH4 values and the methane/ (ethane 1 propane) ratios of the gas indicate that the primary origin of the methane is by thermogenic decomposition of coal-bearing beds in the Haboro or Hakobuchi formations, or further deep sources. This study provides new data on processes of onshore mud volcanism in Japan, and contributes to an understanding of processes of subsurface mass transport in regions of mud-volcanic activity.
