smaller earthquakes at Mt. Fuji which could indicate the movement of magma underground inside the volcanic system.

smaller fault segments, forming mature rupture zones with a potential for larger
earthquake,» said Marco Bohnhoff, professor of geophysics
at the German Research Center for Geosciences in Potsdam, Germany, who sought to clarify the seismic hazard potential from the NAFZ.
The
earthquakes at Axial Seamount are

The
earthquake — estimated
at magnitude 9.0 on the Richter scale — occurred in a total area much
smaller than previous large
earthquakes, such as the 8.8 Chilean
earthquake last year, arguing that the slippage was much greater for the Japan quake, one of the four most powerful
earthquakes on record.
ROME — A project to drill deep into the heart of a «supervolcano» in southern Italy has finally received the green light, despite claims that the drilling would put the population of Naples

The preliminary results from the Cascadia Initiative include a report of previously undetected,

at the subduction zone.
Last year's gigantic landslide
at a Utah copper mine probably was the biggest nonvolcanic slide in North America's modern history, and included two rock avalanches that happened 90 minutes apart and surprisingly triggered 16
small earthquakes, University of Utah scientists discovered.
Past research has shown that processes such as wastewater injection
at oil drilling and fracking sites throughout the state could induce a
small number of
earthquakes but scientists have never been able to specifically link some of the more distant or stronger
earthquakes with these sometimes faraway wastewater wells.
Yes, albeit on a much
smaller scale than the 2011 Japan
earthquake and tsunami, according to computer models used by a team of researchers, led by seismologists
at the University of California, Riverside.
Emile Okal
at Northwestern University in Illinois cautions that this theoretical approach may only be valid for
small earthquakes.
The mathematical expression of the law
at the seismic moment, proposed by Serra and Corral, meets all the conditions needed to determine both the probability of
smaller earthquakes and of large ones, by adjusting itself to the most recent and extreme cases of Tohoku, in Japan (2011) and Sumatra, in Indonesia (2004); as well as to determine negligible probabilities for
earthquakes of disproportionate magnitudes.
Making it useful

smaller, such as the mantle activity beneath Southern California or the
earthquake - prone crust of Istanbul, will require additional work.

earthquakes is... partly propagated by waves, which succeed one another sometimes
at larger and sometimes
at smaller distances.»
Over the wide frequency range of seismic waves transmitted through the Earth (hundreds of seconds to ten cycles per second), the sensors of the permanent and transportable seismic and magnetotelluric arrays will resolve the
smallest background motions
at the quietest of sites, while remaining «on scale» for all but the largest ground motions from regional
earthquakes.
