M 7.2 - 98 km S of Sand Point, Alaska; Shishaldin Volcano erupting

In summary, a magnitude 7.2 earthquake occurred 98 km south of Sand Point, Alaska on July 16, 2023. This event has raised concerns about a potential eruption of the nearby Shishaldin Volcano, as there have been reports of increased activity and ash emissions since July 11. The volcano is located on Unimak Island, which has a small population that may need to evacuate depending on the severity of the eruption. Further monitoring and updates from the Alaska Volcano Observatory will be necessary to determine the potential impact of the earthquake on the volcano.

M 7.2 - 98 km S of Sand Point, Alaska​

  • 2023-07-16 06:48:22 (UTC)
  • 54.460°N 160.760°W
  • 32.6 km depth

There is some speculation that the Mag 7.2 earthquake may be indicative of an imminent eruption of the Shishaldin Volcano.
The volcano coordinates are: 54°45′21″N 163°58′03″W Similar latitude, but about 3.3° longitude west.

A massive 7.2 magnitude earthquake has increased the risk of a volcano in Alaska erupting imminently as the aviation level was raised to red.

The Shishaldin Volcano has been spewing great plumes of ash into the air since July 11, according to the Alaska Volcano Observatory (AVO).

A US Coast Guard overflight confirmed lava erupted the same day within the summit crater.

The latest data from the AVO, as of just before midnight on July 15, showed frequent explosion signals are being detected, with some explosions sending plumes of ash as high as 20,000 ft above sea level.

Oh my! I hope no one lives near the volcano.

The volcano is located on Unimak Island, which is sparsely populated. In 2000, there were 24 people on the island. A recent article indictes about 60 people live on the Island, but that may be seasonal, and now with the volcano erupting, perhaps they will evacuate.

FAQ: M 7.2 - 98 km S of Sand Point, Alaska; Shishaldin Volcano erupting

What caused the M 7.2 earthquake near Sand Point, Alaska?

The M 7.2 earthquake near Sand Point, Alaska, was caused by tectonic activity associated with the movement of the Pacific Plate and the North American Plate. This region is seismically active due to the complex interactions of these tectonic plates, which can lead to significant earthquakes.

How does the eruption of Shishaldin Volcano relate to the earthquake?

The eruption of Shishaldin Volcano may be influenced by the seismic activity in the region. Earthquakes can generate pressure changes in the Earth's crust, potentially triggering volcanic eruptions. However, the specific relationship between an earthquake and a volcanic eruption can vary and is studied on a case-by-case basis.

What are the potential hazards associated with the earthquake and volcanic eruption?

The potential hazards from the earthquake include ground shaking, tsunamis, and aftershocks, which can cause structural damage and pose risks to life. The volcanic eruption can produce ashfall, pyroclastic flows, and lava flows, which can affect air quality, disrupt transportation, and pose risks to nearby communities.

How can residents prepare for earthquakes and volcanic eruptions in Alaska?

Residents can prepare by having an emergency kit, developing a family emergency plan, and staying informed about local hazards. It is also important to know evacuation routes and to participate in community drills. Familiarizing oneself with earthquake safety measures and understanding volcanic activity can enhance preparedness.

Where can I find more information about seismic activity and volcanic eruptions in Alaska?

More information can be found through the Alaska Earthquake Center, the United States Geological Survey (USGS), and the Alaska Volcano Observatory. These organizations provide real-time data, research, and resources related to seismic and volcanic activity in the region.
