The 2014 Palma Bay earthquake occurred at 02:54 Alaska Daylight Time on July 25 in the northern southeastern panhandle of the U.S. state of Alaska. The earthquake registered 6.0 on the moment magnitude scale and had a maximum Mercalli intensity of IV (Light). It was centered on Palma Bay, 26 miles (42 km) from Elfin Cove and 94 miles (151 km) from the state capital of Juneau. [1] Although there were no injuries or deaths, there were significant disruptions to Internet and telecommunications throughout Southeast Alaska, including to major telecom providers Alaska Communications Systems (ACS) and AT&T wireless, Internet and other communication systems.
The earthquake struck along the strike-slip Queen Charlotte Fault, connecting Alaska's Aleutian Islands tectonic area with Southeast Alaska. [3] The mainshock was preceded by less than one minute by a M5.4 foreshock in the immediate area. There were also a number of other M5 or higher events in the days leading up to the main event, but Alaska state seismologist Michael West stated that there was no evidence that they were related. [4]
The earthquake caused widespread outages to telecommunications in Southeast Alaska. Cellphone, Internet and other communications were disrupted for customers of ACS and AT&T throughout the day. Businesses in the area were unable to process credit card transactions, and many local websites were inaccessible. [5] Outages were caused by damage to undersea fiber-optic cable serving the area. Other outages included the website of Alaska Electric Light & Power, the area's largest provider of electricity, although electrical service was not disrupted. [6]
Juneau, officially the City and Borough of Juneau, is the capital of the U.S. state of Alaska, located along the Gastineau Channel and the Alaskan panhandle. Juneau was named the capital of Alaska in 1906, when the government of what was then the District of Alaska was moved from Sitka as dictated by the U.S. Congress in 1900. On July 1, 1970, the City of Juneau merged with the City of Douglas and the surrounding Greater Juneau Borough to form the current consolidated city-borough, which ranks as the second-largest municipality in the United States by area and is larger than either Rhode Island or Delaware.
The Fukuoka earthquake, also known as the Fukuoka Prefecture West Sea Earthquake, struck Fukuoka Prefecture, Japan at 10:53 am JST on March 20, 2005, off the northwest coast of Fukuoka Prefecture, and lasted for approximately 1 minute. The Japan Meteorological Agency (JMA) measured it as peaking at a magnitude of 7.0 and a maximum seismic intensity of less than six, whereas the United States Geological Survey (USGS) reported a magnitude of 6.6. The quake occurred along a previously unknown fault in the Genkai Sea, North of Fukuoka city, and the residents of Genkai Island were forced to evacuate as houses collapsed and multiple landslides occurred in various places. Investigations subsequent to the earthquake determined that the new fault was most likely an extension of the known Kego fault that runs through the centre of the city.
Alaska Communications is a telecommunications corporation headquartered in Anchorage, Alaska. It was the first telecommunications provider in the state of Alaska to maintain a third-generation wireless network and the only provider in Alaska that owned fully incorporated infrastructure for the major telecommunications platforms; wireless communications, Internet networking, and local and long-distance phone service. Alaska Communications wireline operations include advanced data networks and an underwater fiber optic system. The Alaska Communications wireless operations included a statewide 3G CDMA network, and coverage extended from the North Slope to Southeast Alaska.
APCN 2 or Asia-Pacific Cable Network 2 is a submarine telecommunications cable linking several countries in the Asia-Pacific region.
The 2006 Hengchun earthquakes occurred on December 26 at 20:26 and 20:34 local time off the southwest coast of Taiwan in the Luzon Strait, which connects the South China Sea with the Philippine Sea. The International Seismological Centre measured the shocks at 7.0 and 6.9 on the moment magnitude scale. The earthquakes not only caused casualties and building damage, but several submarine communications cables were cut, disrupting telecommunication services in various parts of Asia.
The 2008 Chino Hills earthquake occurred at 11:42:15 am PDT on July 29 in Southern California. The epicenter of the magnitude 5.4 earthquake was in Chino Hills, c. 28 miles (45 km) east-southeast of downtown Los Angeles. Movement on an oblique-slip fault resulted in a maximum Mercalli intensity of VI (Strong). Though there were no deaths, eight people were injured, and it caused considerable damage in numerous structures throughout the area and caused some amusement park facilities to shut down their rides. The earthquake led to increased discussion regarding the possibility of a stronger earthquake in the future.
The Asia-America Gateway (AAG) is a 20,000-kilometre (12,000 mi) long submarine communications cable system, connecting South-East Asia with the mainland of the United States, across the Pacific Ocean via Guam and Hawaii.
The 2016 Old Iliamna earthquake struck in the Cook Inlet region of Alaska near Iliamna at 1:30 AM AKST on January 24, 2016. The quake was centered approximately 162 miles (261 km) from Anchorage, and 65 miles (105 km) from Homer. The earthquake registered 7.1, and was felt across a wide area of Southcentral Alaska, the Kenai Peninsula and as far away as Juneau roughly 700 miles (1,100 km) southeast of the epicenter. Moderate to heavy damage to homes, roads and businesses was experienced over a wide area.
On January 23, 2018, at 00:31 AKST, an earthquake occurred in the Gulf of Alaska near Kodiak Island. The earthquake, measured at 7.9 on the Mw scale, was approximately 280 kilometers (170 mi) southeast of Kodiak and happened at a depth of 25 kilometers (16 mi).
