...Hongyu Yu; Yajing Liu; Rebecca M. Harrington; Maurice Lamontagne Abstract The Charlevoix seismic zone ( CSZ ) in Québec has the highest number of earthquakes in eastern Canada, with cataloged events diffusely distributed between the St. Lawrence paleorift faults. In this study, we relocate 1242 out...

...Arthur Frankel Abstract The decay of the Fourier spectral amplitudes of S waves over distances of 10–80 km near Charlevoix, Quebec, was determined using waveforms from seven earthquakes with M N 3.3–5.4. The S ‐wave spectral amplitudes were corrected for site response and source amplitude...

...John E. Ebel 6 June 2013 I thank Alan Ruffman for his informative comment on my recent paper that presented an analysis of the magnitude of the 1663 Charlevoix, Quebec, earthquake. Ruffman accurately describes our communications about this earthquake, and I appreciate his setting...

...John E. Ebel; Megan Dupuy; William H. Bakun Abstract The Charlevoix, Quebec, earthquake of 20 October 1870 caused damage to several towns in Quebec and was felt throughout much of southeastern Canada and along the U.S. Atlantic seaboard from Maine to Maryland. Site‐specific damage and felt reports...

...John E. Ebel Abstract This paper presents a new and comprehensive analysis of the magnitude of the 1663 Charlevoix, Quebec, earthquake. Based on a modified Mercalli intensity scale ( MMI ) of about VI from reports of damage to chimneys and a masonry wall in Roxbury and Boston, Massachusetts...

... by any official document ( Leblanc, 1981 ) and is now considered an unfounded rumor ( Gouin, 2001 ). Another rejected hypothesis was that the 20 October 1870 Charlevoix mainshock, or one of its aftershocks, caused a landslide that killed four people near Trois-Rivières, Québec. An analysis of official...

The southernmost site with permafrost identified in the Quebec–Labrador peninsula is located on the summit of Lac des Cygnes Mountain, in Charlevoix (47°41′N, 70°36′W), and was discovered...

...C. R. D. Woodgold Abstract Coda Q is determined in the seismically active Charlevoix region, Quebec, using 34 earthquakes recorded on the six-station Charlevoix Local Telemetered Network. For comparison, an average value of coda Q for southeastern Canada is determined from 32 events that occur over...
