Earthquakes in BC Earthquakes in British Columbia British Columbia experiences an earthquake every day, but only a small number of these quakes are noticeable and even fewer result in damage. View of landslide on Mount Colonel Foster triggered by the June 23, 1946 Vancouver Island earthquake (photo courtesy of the Geological Survey of Canada). Several major earthquakes have hit B.C. in the last 100 years and there is a very good chance we will experience large earthquakes in the future. We live in a high-risk zone because of the geological processes that take place within the crust of the Earth in B.C. Plates in the Earth's surface shift to produce earthquakes and the science of geology can help determine which ground types will be most affected by a quake. An important step in ensuring your own safety is to understand the answers to the following questions: What causes earthquakes? How big are earthquakes? Where do they occur? What is a megathrust earthquake? ... How can geology be used to minimize risk? Note: Certain terms used in these pages may be unfamiliar to the non-geologist. They have been hyperlinked to a

New Madrid Earthquakes Oklahoma Geology: Why Do We Have Earthquakes? Background: Oklahoma Geology Although much of Oklahoma belongs to the stable central plains province of the United States, it has been involved in major mounting building and basin forming processes in the past few hundred years. This may help to explain why Oklahoma, although not experiencing major earthquakes activity, nevertheless has a sustained level of seismicity. Major geological provinces in Oklahoma include 4 mountain ranges or uplifts (Ozark Uplift, Wichita Uplift, Arbuckle Uplift and Ouachita Mountains), 5 basins (Anadarko Basin, Arkoma Basin, Ardmore Basin, Marietta Basin and Hollis Basin), and the Northern Shelf Area. In the far western panhandle is Black Mesa. The Nemaha Ridge runs approximately north-south through north central and central Oklahoma. The Gulf Coastal Plain, consisting of young sedimentary rocks, covers the most southeasterly part of the state. Oklahoma Earthquakes Summary Oklahoma averages about 50 to 100 recorded, locatable earthquakes per year. Most earthquakes occur on deep faults that are not visible at the Earth's surface. Oklahoma has thousands of faults in the subsurface, but most of these were created and were last active over 200 million years ago. Only about one or two earthquakes, on average, are reported as "felt" by Oklahoma residents. The largest Oklahoma earthquake ever recorded was the 1952 El Reno earthquake, with a magnitude of about 5.0 to 5.5 on the Richter scale.

The first - with its epicentre at Izmit in Turkey's heavily populated northwest - struck at 0302 hours local time on 17 August. It left some 17,000 people dead and thousands more homeless. The second struck just 100km away on 12 November, killing hundreds more.

12. Plate Tectonics, The Cause Of Earthquakes At spreading ridges, or similar extensional boundaries, earthquakes are shallow, The yellow dots below locate earthquakes along strands of this fault http://www.seismo.unr.edu/ftp/pub/louie/class/100/plate-tectonics.html

Plate Tectonics, the Cause of Earthquakes The plates consist of an outer layer of the Earth, the lithosphere , which is cool enough to behave as a more or less rigid shell. Occasionally the hot asthenosphere of the Earth finds a weak place in the lithosphere to rise buoyantly as a plume, or hotspot. The satellite image below shows the volcanic islands of the Galapagos hotspot. (from NASA) Only lithosphere has the strength and the brittle behavior to fracture in an earthquake. The map below locates earthquakes around the globe. They are not evenly distributed; the boundaries between the plates grind against each other, producing most earthquakes. So the lines of earthquakes help define the plates: (from the USGS) In cross section, the Earth releases its internal heat by convecting, or boiling much like a pot of pudding on the stove. Hot asthenospheric mantle rises to the surface and spreads laterally, transporting oceans and continents as on a slow conveyor belt. The speed of this motion is a few centimeters per year, about as fast as your fingernails grow. The new lithosphere, created at the ocean spreading centers, cools as it ages and eventually becomes dense enough to sink back into the mantle. The subducted crust releases water to form volcanic island chains above, and after a few hundred million years will be heated and recycled back to the spreading centers. Earthquake occurrence in different plate tectonic settings: The map below of Earth's solid surface shows many of the features caused by plate tectonics. The oceanic ridges are the asthenospheric spreading centers, creating new oceanic crust. Subduction zones appear as deep oceanic trenches. Most of the continental mountain belts occur where plates are pressing against one another. The white squares locate examples given here of the different tectonic and earthquake environments.
