If Mount Redoubt complete erupts could it trigger earthquakes in California?

1. Could a massive eruption in Alaska trigger the faults to slip in California?
2. The condition is Orange and watch is 24/7 with small quakes
3. Mount Redoubt has erupt six previous occurrences
4. Will this eruption be worst than Mount St. Helens?
5. Ash was falling 50 miles away in North Anchorage.

What is your interpretation of the seismic activity events?

The simple answer is yes, although it would seem to require a lot of geological events to coincide.

According to Chun-Feng Li, Structural Geologist:

Humans see volcanoes and earthquakes as two different types of natural disasters but they often can be closely related. Both are part of the plate tectonic cycle. Volcanic eruptions or magma activities can trigger numerous earthquakes and micro-earthquakes (earthquakes of very small magnitudes), many of which are imperceptible to human beings but can be recorded by seismometers. In fact, scientists can monitor or predict the imminent eruption of a volcano based on the sharp changes in numbers of earthquakes recorded around the volcano.

Just as volcanic activities can trigger earthquakes, theoretically earthquakes can alter the subsurface stress field and trigger volcanic eruptions as well. But these are rare scenarios because there are far fewer active volcanoes on the Earth today than the number of earthquake events that occur each day.

Asker's Rating:
• Has a math model been created that show how a earthquake in one region affects fault lines in other regions?

I doubt it. Mount Redoubt is a long way from the fault line between the Pacific plate and the North American plate. In addition, much of California is on the Pacific plate while Mount Redoubt is on the North American plate.

What if both plates are experiencing seismic activity? Redoubt has seismic activity and California is experiencing low seismic activity. Could energy from one plate aid in the energy build up of another distance plate?
