Fissure 8 is spewing lava like crazy.

A lot of people have been talking about the connection between volcanic eruptions and earthquakes. I'm not a geologists but many claim the increase in volcanic activity may be a harbinger of potential earthquakes. It'scary because there a number of dangerous regions here in the US that are way behind schedule.

The Cascadia Subduction Zone is a plate boundary just off the coast of the Pacific Northwest. A severe earthquake normally strikes the area every 240 years but the last major activity was in 1700.

The New Madrid Seismic Zone in the southern and midwestern US has not had a major earthquake since 1811 - 1812. It's past due for a major quake. The last time it shook hard, the shock waves were felt as far away as Washington DC.

And, of course, The San Andreas Fault is famously past due. Prophets of doom love to speak of how they believe California will be devastated.

Actually its earthquakes that are often a sign of pending volcanic activity.......that's assuming they are near a volcano in the first place. A volcanic eruption in Hawaii isn't about to cause the New Madrid Seismic Zone to go off. This seismic zones will go off when enough pressure builds up.

Based on the info in your links it doesn't look like Cascadia or New Madrid are overdue.......but both locations should be prepared for the quakes that each seismic zone is capable of. However, I kind of doubt Memphis or Saint Louis are as ready as the Pacific Northwest. The Pacific Northwest also have to be prepared for a tsunami where as the other two locations do not.

I'd also like to add that Yellowstone is not "overdue".

We started having earthquakes here in Oklahoma,well i guess we always had them we just couldnt ever feel them. but one a couple years ago was a 5.5 . As of volcano's here i think the closest would be the Black Mesa.

I'm on the East Coast but I live in a 100 yr old brick veneer house. It would never survive a major earthquake. We had a minor quake 7 years ago and several slates came loose from the roof.

According to Michio Kaku, the cycle for the Cascadia Subduction Zone calls for a major earthquake and subsequent tsunami every 240 years. The last major quake struck in 1700. The next one could potentially be as strong as a magnitude 9.0 quake, followed by a 500 mph tsunami wave.

Like I said its something to be prepared for........but bear in mind there was a gap of 910 years at one point so its not really "overdue".

People in the "inundation zone" have likely no more than 30 minutes to get to cover. Some seaside comunites are building tsunami shelters.

You likely should worry more about the mega-tsunami aimed at the east coast. in that case.

Bear in mind the scientists who studied this first hand differs in your opinion and state that region is overdue and have a higher percentage of probability of an earthquake because it is overdue...

13-year Cascadia study complete - and earthquake risk looms large
"The southern margin of Cascadia has a much higher recurrence level for major earthquakes than the northern end and, frankly, it is overdue for a rupture," said Chris Goldfinger, a professor in OSU's College of Earth, Ocean, and Atmospheric Sciences and lead author of the study. "That doesn't mean that an earthquake couldn't strike first along the northern half, from Newport, Ore., to Vancouver Island.

"But major earthquakes tend to strike more frequently along the southern end - every 240 years or so - and it has been longer than that since it last happened," Goldfinger added. "The probability for an earthquake on the southern part of the fault is more than double that of the northern end."
