2007–2008 Nazko earthquakes
series of earthquakes in Canada
A series of small volcanic earthquakes measuring less than 4.0 on the Richter magnitude scale took place in the sparsely populated Nazko area of the Central Interior of British Columbia, Canada, from October 9, 2007, to June 12, 2008. They occurred just west of Nazko Cone, a small tree-covered cinder cone that last erupted about 7,200 years ago.
No damage or casualties resulted from the Nazko earthquakes, which were too small to be felt by people, but local seismographs recorded them. The earthquake swarm occurred at the eastern end of a known volcanic zone called the Anahim Volcanic Belt. This is an east–west trending line of volcanic formations extending from the Central Coast to the Central Interior of British Columbia.
Geology
The 2007–2008 Nazko earthquake swarm is interpreted to have originated 25 kilometres (16 miles) below the surface. The character of the seismic waves indicated the swarm originated from a magmatic source. It could have resulted from rock fracturing at the tip of a dike and/or by movement along fault planes due to changes in the local stress field by the expansion and movement of magma. This magmatic activity is potentially linked to the Anahim hotspot, a mantle plume that is responsible for older volcanism throughout the Anahim Volcanic Belt. The volcanoes in this volcanic zone generally become older to the west, indicating the North American Plate is moving in a westerly direction with respect to the hotspot, carrying the volcanoes along with it at a rate of about 2.5 centimetres (0.98 inches) per year.
“2007–2008 Nazko earthquakes” enters the record as series of earthquakes in Canada. Crown Archives preserves that source wording while asking what Nazko, earthquakes and series can confirm, complicate or overturn.
Why this record matters
“2007–2008 Nazko earthquakes” is worth following because a concise public description often conceals a longer documentary argument. Here, Nazko, earthquakes and series provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 6, 2026. The linked authority identifier is Q4610352. Authority coordinates are 52.880, -124.080. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2007 and 2008.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
