Australia is in a unique position globally being a continent where Mw7.0 events can occur in the Craton, and potentially similar large events in the non-Craton areas, however only a recorded history of around 150-200 years or less exists in most locations. Although a lowmoderate seismicity country, many locations have already experienced damaging earthquakes. The recent earthquake hazard maps i...

S U M M A R Y Motivated by a recent resurgence in earthquake predictability research, we present a method for testing alarm-based earthquake predictions. The testing method is based on the Molchan diagram—a plot of miss rate and fraction of space–time occupied by alarm—and is applicable to a wide class of predictions, including probabilistic earthquake forecasts varying in space, time, and magn...

the investigation of this paper focuses on eastern part of shahroud fault system in middle-east alborz. this fault system is an important part in the seismotectonic map of the area. we used two local temporary dense seismological networks data installed around the fault system for several months during 2007 and 2008 and simultaneously micro-earthquakes data recorded by the permanent seismologic...

A surprising increase in seismicity started in and around Monticello Reservoir, South Carolina in December 1996, and by the end of 1999, over 700 earthquakes with 0.4 ML 2.5 had been located. This seismicity occurred in a new hypocentral region and filled the gaps in earlier seismicity at depths shallower than 2 km. The seismicity occurred in four episodes each with at least one earthquake of m...

Continental intraplate seismicity seems often episodic, clustered, and migrating. The observed seismicity shows both spatial clustering in seismic zones and scattering across large plate interiors, temporal clustering followed by long periods of quiescence, and migration of seismicity from one seismic zone to another. Here, we explore the complex spatiotemporal patterns of intraplate seismicity...

Using the simple ETAS branching model of seismicity, which assumes that each earthquake can trigger other earthquakes, we quantify the role played by the cascade of triggered seismicity in controlling the rate of aftershock decay as well as in the overall level of seismicity in the presence of a constant external seismicity source. We show that, in this model, the proportion of triggered seismi...

In the year 2000, an anomalous sequence of off-fault seismicity was detected near Lake Pillsbury in northern California. The seismicity was interpreted by Hayes et al. (2005, 2006) to be associated with a dike injection. I completed a gravity survey over the location of the seismicity and used that data in gravity modeling, to test the hypothesis that the seismicity was directly linked to the i...

A system for extracting and visualizing trend information about earthquakes from tagged corpus, which is distributed by a Workshop on Multimodal Summarization for Trend Information (MuST), is proposed. The topic of earthquakes does not contain only temporal trends, which are main concerns of typical topics such as gas price and stock price movement, but also spatial trends including the seismic...

The Mw 7.9 Denali fault earthquake ruptured segments of the Susitna Glacier, Denali, and Totschunda faults in central Alaska, providing a unique opportunity to look for intermediate-term (weeks to months) responses of active volcanoes to shaking from a large earthquake. The Alaska Volcano Observatory (AVO) monitors 24 volcanoes with seismograph networks. We examined one station per volcano. Dig...
