Induced seismicity associated with fluid injection into a deep well in Youngstown, Ohio
[1] Over 109 small earthquakes (Mw 0.4–3.9) were detected during January 2011 to February 2012 in the Youngstown, Ohio area, where there were no known earthquakes in the past. These shocks were closeExpand

CoMine: efficient mining of correlated patterns
We re-examine this problem and show that two interesting measures, all-confidence (denoted as /spl alpha/) and coherence, both disclose genuine correlation relationships and can be computed efficiently. Expand

The corner frequencies and stress drops of intraplate earthquakes in the northeastern United States
This article presents the estimation of stress drops for small to middle-sized intraplate earthquakes in the northeastern United States. The vertical-component Sg and Lg waves of 49 earthquakes wereExpand

The Applicability of Modern Methods of Earthquake Location
We compare traditional methods of seismic event location, based on phase pick data and analysis of events one-at-a-time, with a modern method based on cross-correlation measurements and jointExpand

A Fluid-Injection-Triggered Earthquake Sequence in Ashtabula, Ohio: Implications for Seismogenesis in Stable Continental Regions
A persistent earthquake sequence in northeast Ohio includes many distinct fore-main-aftershock subsequences, illuminates two faults, and was triggered by fluid injection. The first known earthquakeExpand

The 20 January 2007 Odaesan, Korea, Earthquake Sequence: Reactivation of a Buried Strike-Slip Fault?
The M w 4.6 Odaesan, Korea, earthquake of 20 January 2007 (11 hr 56 min) had nine locatable foreshocks in the previous 67 hours and nine aftershocks during the 11 hours after the main event. WeExpand

Crustal structure and tectonics of Bangladesh: New constraints from inversion of receiver functions
Abstract An understanding of the sedimentary and crustal structure of the Bengal Basin and of the tectonics deforming it remains elusive due to lack of seismic data from Bangladesh. Taking advantageExpand
