Methane expulsion from the world ocean floor is a broadly observed phenomenon known to
be episodic. Yet the processes that modulate seepage remain elusive. In the Arctic offshore …

We analyzed seismicity linked to the 2014 phreatic eruption of Mount Ontake, Japan, on 27
September 2014. We first relocated shallow volcano tectonic (VT) earthquakes and long …

Abstract The World Organization of Volcano Observatories (WOVO), with major support from
the Earth Observatory of Singapore, is develo** a web-accessible database of seismic …

We present petrological evidence of the shallow magmatic processes that may have
supplied heat and gas to the eruption of Mount Ontake, Japan, on 27 September 2014 …

Abstract During the Pleistocene, Earth's climate changed dramatically. The mid-Pleistocene
transition (MPT;~ 1.3–0.7 million years (Ma)) featured an important ice volume increase at …

We analyze the spatiotemporal distribution of fault geometries from seismicity induced by
fluid injection at The Geysers geothermal field. The consistency of these faults with the local …

To investigate the applicability of frictional reactivation theory to active faults, we evaluated
the slip tendency of active faults in Japan. Slip tendency is defined as the ratio of shear …

Volcanic activity is often accompanied by many small earthquakes. Earthquake focal
mechanisms represent the fault orientation and slip direction, which are influenced by the …

Microseismic swarm activity has taken place since 1976 around Mt. Ontake, the second
highest stratovolcano in Japan. This activity is thought to be linked to high pore-fluid …

This paper presents a framework designed to collect, archive, and share time series data
coming from sensor networks at Istituto Nazionale di Geofisica e Vulcanologia, Osservatorio …
