11/24/2023 0 Comments Alaska quake centerGridded ground motion data and mapped gridded ground motion values are available for the 1999 Alaska Seismic Hazard Model. ![]() The original dataset was assumed to be complete and accurate, but may contain inconsistencies when compared to more recent, actively maintained datasets. The original dataset was uploaded to the USGS website at the time of publication of the seismic hazard model (2007) but was later moved over the the USGS ScienceBase Catalog (2019). This dataset is considered a legacy dataset. Development of the 2007 Alaska Seismic Hazard Model is documented in the USGS Open-File Report 2007-1043 ( ). Time-independent probabilistic seismic hazard data and maps of Alaska and the Aleutians for peak ground acceleration (PGA) and 0.1, 0.2, 0.3, 0.5, 1.0 and 2.0 second spectral acceleration at probability levels of 2 percent in 50 years (annual probability of 0.000404), 5 percent in 50 years (annual probability of 0.001026), and 10 percent in 50 years (annual probability of 0.0021) assuming firm rock soil conditions at 760 m/s are available. © 2023 NYP Holdings, Inc.Gridded seismic hazard curve data, gridded ground motion data, and mapped gridded ground motion values are available for the 2007 Alaska Seismic Hazard Model. “In Alaska, we are still lacking as far as infrastructure development, but we are working towards that goal,” Ruppert said. Meanwhile, scientists at the Alaska Earthquake Center say they hope to create an early warning system like the ones used in California, Oregon and Washington. Giving people the facts, so they understand – not what they’re up against, but what they’re dealing with,” Gardine said. They also fight misinformation about potential aftershocks or damage reports in the wake of an earthquake. “We get tweets and Facebook messages and things like that sometimes while it’s still shaking,” Lea Gardine, Seismologist and Communications Manager for the Alaska Earthquake Center, said. The center also educates people about earthquake safety and gets the word out about earthquake events on social media. Alaska is the site of the second biggest earthquake on record. Luckily, large earthquakes like the one in 1964 are relatively rare.īut big or small, the Alaska Earthquake Center is constantly monitoring the ground for movement with its series of sensors. It also caused a large tsunami,” Ruppert said about the Good Friday earthquake. “Violent ground shaking caused lots of structures and buildings to collapse. It was a 9.2 tremor that killed 131 people. Probably the most well-known Alaskan earthquake was the Good Friday earthquake of 1964. Scientists say an earthquake happens in Alaska once every ten minutes. “All those interactions are continuously causing earthquakes,” Ruppert said. ![]() And also, because we have many, many faults here.”įault lines are cracks in the earth where blocks of rock move past each other. Ruppert says that Alaska has so many earthquakes because “ It’s the largest state. Alaska experiences more earthquakes than any other state in the US. Scientists say that one happens about every 10 minutes in Alaska, and according to the USGS, Alaska is the site of the second-largest earthquake ever recorded. ![]() “It’s kind of halfway between Fairbanks and Anchorage,” Ruppert said.Įarthquakes are nothing new in the state. Gorden watched as squiggles appeared on a screen.Īnd even though Ruppert said that nobody likely felt it, the earthquake registered as a magnitude 1.5 on the seismic sensors in south-central Alaska. “Oh, here’s an earthquake in Alaska,” Natalia Ruppert, Alaska Earthquake Center Senior, said. So in 1987, the Alaska Earthquake Center was founded to monitor and research what happens when one of these events strikes.įOX Weather’s Max Gorden visited the Alaska Earthquake Center in Fairbanks and was able to see an earthquake unfold right before his eyes. And while many of the earthquakes shake unpopulated parts of the Last Frontier, a group of scientists is keeping tabs on the tremors.Įarthquakes in Alaska are part of everyday life due to the state being extremely seismically active.
