The M7.0 left Alaska shaken, and the aftershocks keep coming. Here's how it looks in the Earth's crust
Alaska earthquake scientists released a cross-section view of the 7.0 magnitude earthquake that shook Alaskans last week.
In the image, the primary earthquake can be seen, as well as the resulting aftershocks. Additionally, the Alaska Earthquake Center specified how close the quake was to Anchorage, Big Lake, and the Mat-Su communities.
According to the AKEC, the region which was upended and ruptured during the quake is called the "rupture patch," and the aftershocks displayed in the image measure 15-25 miles wide.
"They also show that the earthquake occurred inside the Pacific tectonic plate where it is moving under Alaska, and that the earthquake ruptured upward and to the north, the AKEC said in a statement. "This took something close to a dozen seconds."
Due to this, the Earthquake Center said that similar shaking was observed across the region due to being 25 miles beneath Anchorage and Mat-Su.
As a disclaimer, AKEC said that most of the aftershocks still need to be reviewed by a seismologist.
