6.2 earthquake off Baja is quickly followed by aftershocks
September 25, 2012 | 6:09 pm

A 6.2 magnitude earthquake off the coast of Baja California has quickly been followed by at least two others.

The earthquake occurred in the ocean, 47 miles north-northeast of La Paz, off the coast of Baja California Peninsula in Mexico, the U.S. Geological Service reported Tuesday. That’s also about 604 miles south-southeast of Phoenix.

The shaker struck about 4:45 p.m Los Angeles time at a depth of 6.3 miles. Twenty minutes later, a second quake of magnitude 4.2 was recorded. A third quake, with a magnitude of 4.8, occurred 12 minutes after the second.

There was no immediate word on damage or injuries.

The area west of the Gulf of California, including the Baja California Peninsula, is moving northwestward with the Pacific plate at a speed of about 95 millimeters per year. Plate motion has pulled Baja California away from the coast, forming the Gulf of California and is the cause of earthquakes in that region, according to the USGS.

Mexico has a long history of destructive earthquakes. In September 1985, a magnitude 8.1 earthquake killed more than 9,500 people in Mexico City.

'Things were shaking': Powerful earthquake rocks remote Alaska island
By Reuters
ANCHORAGE, Alaska - A powerful earthquake rocked one of the few inhabited islands in Alaska's Aleutian chain on Wednesday, but no damage has been found, federal and local officials said.

The magnitude 6.9 quake, centered 80 miles southwest of Adak, struck at 3:40 p.m. local time (7.40 p.m. ET), the West Coast and Alaska Tsunami Warning Center said. No tsunami warning was issued, but scientists will monitor the area for any possible earthquake-related waves, center Director Paul Whitmore said.
In Adak, a community of about 330, "We definitely felt it," City Manager Layton Lockett said.

The building that houses city offices and the local school, engineered to withstand frequent earthquakes that strike the region, performed as designed, Lockett said.

"You could just hear the building move, and things were shaking," he said.

No damage was found, though officials were concerned about the fate of underground pipes, he said. The school, which has about 20 students, was out of session at the time.

Adak, an island city about 1,300 miles southwest of Anchorage, is a converted U.S. Navy station that once housed 6,000 people. It now operates as a port and seafood-processing center serving the North Pacific commercial fishing fleet.

Other moderate earthquakes have struck western Alaska in recent days, according to the center.

A magnitude 4.9 quake was recorded 90 miles west of the Alaska Peninsula town of Cold Bay on Tuesday. A magnitude 5.2 quake about 90 miles southwest of Kodiak was recorded on September 18.

That area has a fascinating geologic history.

Tectonic Summary

Seismotectonics of the Aleutian Arc

The Aleutian arc extends approximately 3,000 km from the Gulf of Alaska in the east to the Kamchatka Peninsula in the west. It marks the region where the Pacific plate subducts into the mantle beneath the North America plate. This subduction is responsible for the generation of the Aleutian Islands and the deep offshore Aleutian Trench.

The curvature of the arc results in a westward transition of relative plate motion from trench-normal (i.e., compressional) in the east to trench-parallel (i.e., translational) in the west, accompanied by westward variations in seismic activity, volcanism, and overriding plate composition. The Aleutian arc is generally divided into three regions: the western, central, and eastern Aleutians. Relative to a fixed North America plate, the Pacific plate is moving northwest at a rate that increases from roughly 60 mm/yr at the arc's eastern edge to 76 mm/yr near its western terminus. The eastern Aleutian arc extends from the Alaskan Peninsula in the east to the Fox Islands in the west. Motion along this section of the arc is characterized by arc-perpendicular convergence and Pacific plate subduction beneath thick continental lithosphere. This region exhibits intense volcanic activity and has a history of megathrust earthquakes.

The central Aleutian arc extends from the Andreanof Islands in the east to the Rat Islands in the west. Here, motion is characterized by westward-increasing oblique convergence and Pacific plate subduction beneath thin oceanic lithosphere. Along this portion of the arc, the Wadati-Benioff zone is well defined to depths of approximately 200 km. Despite the obliquity of convergence, active volcanism and megathrust earthquakes are also present along this margin.

The western Aleutians, stretching from the western end of the Rat Islands in the east to the Commander Islands, Russia, in the west, is tectonically different from the central and eastern portions of the arc. The increasing component of transform motion between the Pacific and North America plates is evidenced by diminishing active volcanism; the last active volcano is located on Buldir Island, in the far western portion of the Rat Island chain. Additionally, this portion of the subduction zone has not hosted large earthquakes or megathrust events in recorded history. Instead, the largest earthquakes in this region are generally shallow, predominantly strike-slip events with magnitudes between M5-6. Deeper earthquakes do occur, albeit rather scarcely and with small magnitudes (M<4), down to approximately 50 km.

Most of the seismicity along the Aleutian arc results from thrust faulting that occurs along the interface between the Pacific and North America plates, extending from near the base of the trench to depths of 40 to 60 km. Slip along this interface is responsible for generating devastating earthquakes. Deformation also occurs within the subducting slab in the form of intermediate-depth earthquakes that can reach depths of 250 km. Normal faulting events occur in the outer rise region of the Aleutian arc resulting from the bending of the oceanic Pacific plate as it enters the Aleutian trench. Additionally, deformation of the overriding North America plate generates shallow crustal earthquakes.

The Aleutian arc is a seismically active region, evidenced by the many moderate to large earthquakes occurring each year. Since 1900, this region has hosted twelve large earthquakes (M>7.5) including the May 7, 1986 M8.0 Andreanof Islands, the June 10, 1996 M7.9 Andreanof Islands, and the November 17, 2003 M7.8 Rat Islands earthquakes. Six of these great earthquakes (M8.3 or larger) have occurred along the Aleutian arc that together have ruptured almost the entire shallow megathrust contact. The first of these major earthquakes occurred on August 17, 1906 near the island of Amchitka (M8.3) in the western Aleutian arc. However, unlike the other megathrust earthquakes along the arc, this event is thought to have been an intraplate event occurring in the shallow slab beneath the subduction zone interface.

The first megathrust event along the arc during the 20th century was the November 10, 1938 M8.6 Shumagin Island earthquake. This event ruptured an approximately 300 km long stretch of the arc from the southern end of Kodiak Island to the northern end of the Shumagin Islands and generated a small tsunami that was recorded as far south as Hawaii.

The April 1, 1946 M8.6 Unimak Island earthquake, located in the central Aleutian arc, was characterized by slow rupture followed by a devastating Pacific-wide tsunami that was observed as far south as the shores of Antarctica. Although damage from earthquake shaking was not severe locally, tsunami run-up heights were recorded as high as 42 m on Unimak Island and tsunami waves in Hilo, Hawaii also resulted in casualties. The slow rupture of this event has made it difficult to constrain the focal mechanism and depth of the earthquake, though it is thought to have been an interplate thrust earthquake.

The next megathrust earthquake occurred along the central portion of the Aleutian arc near the Andreanof Islands on March 9, 1957, with a magnitude of M8.6. The rupture length of this event was approximately 1200 km, making it the longest observed aftershock zone of all the historic Aleutian arc events. Although only limited seismic data from this event are still available, significant damage and tsunamis were observed on the islands of Adak and Unimak with tsunami heights of approximately 13 m.

The easternmost megathrust earthquake was the March 28, 1964 M9.2 Prince William Sound earthquake, currently the second largest recorded earthquake in the world. The event had a rupture length of roughly 700 km extending from Prince William Sound in the northeast to the southern end of Kodiak Island in the southwest. Extensive damage was recorded in Kenai, Moose Pass, and Kodiak but significant shaking was felt over a large region of Alaska, parts of western Yukon Territory, and British Columbia, Canada. Property damage was the largest in Anchorage, as a result of both the main shock shaking and the ensuing landslides. This megathrust earthquake also triggered a devastating tsunami that caused damage along the Gulf of Alaska, the West Coast of the United States, and in Hawaii.

The westernmost Aleutians megathrust earthquake followed a year later on February 4, 1965. This M8.7 Rat Islands earthquake was characterized by roughly 600 km of rupture. Although this event is quite large, damage was low owing to the region's remote and sparsely inhabited location. A relatively small tsunami was recorded throughout the Pacific Ocean with run-up heights up to 10.7 m on Shemya Island and flooding on Amchitka Island.

Although the Aleutian arc is highly active, seismicity is rather discontinuous, with two regions that have not experienced a large (M>8.0) earthquake in the past century: the Commander Islands in the western Aleutians and the Shumagin Islands in the east. Due to the dominantly transform motion along the western arc, there is potential that the Commander Islands will rupture in a moderate to large strike-slip earthquake in the future. The Shumagin Islands region may also have high potential for hosting a large rupture in the future, though it has been suggested that little strain is being accumulated along this section of the subduction zone, and thus associated hazards may be reduced.

East of the Aleutian arc along the Gulf of Alaska, crustal earthquakes occur as a result transmitted deformation and stress associated with the northwestward convergence of the Pacific plate that collides a block of oceanic and continental material into the North America plate. In 2002, the Denali Fault ruptured in a sequence of earthquakes that commenced with the October 23 M6.7 Nenana Mountain right-lateral strike-slip earthquake and culminated with the November 3, M7.9 Denali earthquake which started as a thrust earthquake along a then unrecognized fault and continued with a larger right-lateral strike-slip event along the Denali and Totschunda Faults.

7.1 magnitude earthquake strikes Colombia
By NBC News and news services
Updated at 2:08 p.m. ET:

A 7.1-magnitude earthquake struck southwestern Colombia on Sunday, the U.S. Geological Survey reported.

The large earthquake rattled residents in the southwest of the Andean nation, but there were no reports of deaths or major damage, authorities said.

"The USGS has received lots of reports that the quake was felt, but no reports of damage or injuries," USGS geophysicist Paul Caruso told NBC News.

The quake was centered 28 miles (45 km) south of Popayan, Colombia, close to the Ecuador border, with a depth of about 103 miles, Colombian officials said.

Its preliminary magnitude of 7.4 was later updated to 7.2, and then 7.1.

"So far there are no reports that there has been damage to any part of the country, only reports that it was felt," Jaime Raigosa, coordinator of the National Seismological Network, said.

"Fortunately, the quake was deep."

The quake struck at 11:31 a.m. local time. It was centered at a depth of about 103 miles, Colombian officials said.

The quake was felt in neighboring Ecuador but authorities reported no damage there.

Tectonic Summary

The October 28th, 2012 (October 27 at the location of the epicenter) M 7.7 earthquake south of Masset, Canada, occurred as a result of oblique-thrust faulting on or near the plate boundary between the Pacific and North America plates. At the location of this event, the Pacific plate moves approximately north-northwest with respect to the North America plate at a rate of approximately 50 mm/yr.

This earthquake is likely associated with relative motion across the Queen Charlotte fault system offshore of British Columbia, Canada. Studies of tectonics in this region suggest plate motions are taken up by strike slip faulting parallel to the plate boundary, accompanied by lesser amounts of thrust motion to accommodate the oblique nature of the plate motion vector between the two plates with respect to the main plate boundary fault structure. It is not clear whether this oblique component of plate motion involves underthrusting of the western edge of the Pacific Plate beneath North America, or whether such motions are taken up on crustal faults. The October 28th earthquake is consistent with either scenario.

This region of the Pacific:North America plate boundary has hosted 7 earthquakes of magnitude 6 or greater over the past 40 years – the largest of which was a M 6.6 earthquake in 2009, 80 km to the south east of the 2012 earthquake. In 1949, a M 8.1 earthquake occurred closer to the Pacific:North America plate boundary, likely as a result of strike-slip faulting, approximately 100 km northwest of the October 28th earthquake, near the northern extent of Haida Gwaii (Queen Charlotte Islands).

A 7.7-magnitude earthquake has struck off the British Columbia coast, triggering a tsunami warning for a region stretching from Vancouver Island to Alaska.

Earthquakes Canada said the quake struck just after 8 p.m. Saturday local time in the Haida Gwaii region. The agency said the quake was felt across much of north-central B.C.

The U.S. Geological Survey made a premliminary report of the quake’s magnitude to be 7.7, but Earthquakes Canada went with 7.1.

There were no immediate reports of injuries or damage.
The quake triggered a tsunami warning from Environment Canada for a region from the north tip of Vancouver Island up to Alaska.
“If you are in a low lying coastal area you are at risk and must move to higher ground or inland now,” the agency said.

“Do not return until directed to do so. Closely monitor local radio stations for additional information from local authorities.”

Emergency Info BC warned that a tsunami is a series of waves that “could last several hours.”

B.C. Premier Christy Clark took to Twitter late Saturday to say the agency is monitoring the situation “and the province is prepared to respond as needed.”

VANCOUVER—A tsunami warning was issued late Saturday for the coastal areas of northwest British Columbia following a 7.7 magnitude earthquake off the waters near Prince Rupert. It was followed by at least aftershocks.

People in coastal areas were told to move inland to higher ground while residents in low-lying coastal areas were ordered to be on alert for instructions from their local emergency officials after the tsunami warning was issued just before 8 p.m. local time.

The epicentre was reported in coastal waters about 40 kilometres south of Sandspit, B.C. at a depth of 19 kilometres.

Natural Resources Canada issued a statement Saturday: “A major earthquake occurred in the Haida Gwaii region. It was felt across much of north-central B.C., including Haida Gwaii, Prince Rupert, Quesnel and Houston. There have been no reports of damage at this time.”

Dave Martynuik, who lives in the village of Queen Charlotte in the Haida Gwaii (formerly known as the Queen Charlotte Islands), described the quake to the Star by phone.

“We were just sitting down relaxing and all of a sudden — boom! I thought it was a major landslide,” said Martynuik. “The epicentre had to be right close to us because the power went out right away. The quake seemed to last forever.”

He said he grabbed his sleeping son and they hung onto cabinets and plants as the house shook. His wife and his daughter had already run outside.

“I’m still kind of shaking. It was just pure hell — totally rocked the house,” he said.

Martynuik, who served in the auxiliary Coast Guard, said he talked to someone at the local marina who said the boats were leaping out of the water into air.

Some people reported feeling the quake as far south as the greater Vancouver area. NDP MLA Mike Farnworth was tweeting that lights in Port Coquitlam were swaying just after 8 p.m.

“We felt the quake,” Farnworth tweeted

The Pacific Tsunami Warning Centre issued the tsunami warning for coastal areas from the northern tip of Vancouver Island to Cape Decision, 135 kilometres southeast of Sitka, Alaska.

It said there was the possibility of “widespread dangerous coastal flooding accompanied by powerful currents.”

The U.S. Geological Survey told the Pacific Tsunami Warning Centre in Hawaii that “based on all available data a destructive Pacific-wide tsunami is not expected and there is no tsunami threat to Hawaii.”
