The 2007 Kuril Islands earthquake occurred east of the Kuril Islands on 13 January at 1:23 p.m. (JST). A Tsunami warning and watch were issued for the entire pacific region after a quake measuring over 8 magnitude was detected off of the coast of the Russian Kuril Islands … On November 15, 2006, Crescent City in Del Norte County, California was hit by a tsunami generated by a M w 8.3 earthquake in the central Kuril Islands. Immediately following that 2006 event, aftershocks began occurring in the epicentral region of this subsequent January 13, 2007, earthquake, leading up to this rupture 2 months later. Kuril Islands earthquake:Tsunami warning & watch canceled. This event is the third largest normal-faulting earthquake seaward of a subduction zone on record, and its rupture zone extended to at least 33 km depth and paralleled most of the length of the 2006 rupture. 2007 earthquake of 13 January 2007 Kuril Islands. Initial tsunami alert bulletins issued by the West Coast Alaska Tsunami Warning Center … The 2007 Kuril Islands earthquake occurred east of the Kuril Islands on 13 January at 1:23 p.m. Japan Standard Time.The shock had a moment magnitude of 8.1 and a maximum Mercalli intensity of VI (Strong).A non-destructive tsunami was generated, with maximum wave amplitudes of .32 meters (1 ft 1 in). Map showing regional bathymetry and tectonic features, along with global centroid moment tensor (CMT) solutions for the larger earthquakes in the 2006–2007 Kuril Islands sequence (focal mechanisms), and NEIC epicenters of activity prior to the doublet (gray circles) between the two largest events (yellow circles), and following the 13 January 2007 event (orange circles). The November 15th earthquake is the largest event to have occurred in the central Kuril Islands since the early 20th century. 1). January 13, 2007 at 2:48 pm Leave a comment. The 2007 earthquake was a normal fault The Kuril Islands form part of the ring of tectonic instability encircling the Pacific Ocean referred to as the Ring of Fire.The islands themselves are summits of stratovolcanoes that are a direct result of the subduction of the Pacific Plate under the Okhotsk Plate, which forms the Kuril Trench some 200 kilometres (124 mi) east of the islands. This earthquake is considered a doublet of the 2007 Kuril Islands earthquake that hit the same area on January 13, 2007. The southwestern half of a ∼500 km long seismic gap in the central Kuril Island arc subduction zone experienced two great earthquakes with extensive preshock and aftershock sequences in late 2006 to early 2007. On 13 January 2007, a second earthquake of comparable magnitude (Mw=8.1; USGS) to the November 2006 earth-quake occurred in the same region but with a source lo-cated on the oceanic slope of the Kuril-Kamchatka Trench, about 100km southeastward of the site of the earlier earth-quake (Fig. On 13 January 2007, an M W = 8.1 extensional earthquake ruptured within the Pacific plate beneath the seaward edge of the Kuril trench. We will present the results of an investigation of the January 13, 2007, Kuril Islands Mw=8.1 normal faulting outer rise earthquake that occurred in close proximity of an Mw=8.3 interplate event that took place two months earlier. Strong currents that persisted over an eight-hour period damaged floating docks and several boats and caused an estimated $9.2 million in losses. The shock had a moment magnitude of 8.1 and a maximum Mercalli intensity of VI (Strong). Our primary interest is in determining the depth extent of its rupture process through the modeling of seismic waveforms and tsunami data.
