Super Volcanoes Around Japan

I was just browsing through RSOE EDIS. I typically check it out daily to see what's going on in the world, and to see if there was anything that I might have missed on the news.

Anyway I got down to the Supervolcano section and i found something a bit disturbing. Maybe more so since the Earthquake. I realize it all happened last month but I was wondering if anyone else noticed this, or what you all think about it. From what I can tell all the Supervolcano's around Japan were recently active in February and early March.

Like I said I was mostly wanting to get input from you all and see what you think,but I really did find it interesting.

Volcanoes all seem to be waking up around the Pacific Rim the past couple of months. Thank you for this it's good info

What I find really distrubing is that none of these volcanoes have reported any seismic activity, despite being in the same country of an earthquake that has made the all time top ten hall of fame

nice website link thanks!
I dont get what it means by last activity for those supervolcanoes in japan - have they showed signs of eruption?

I don't know that is another reason I was posting it here. I was hoping someone could give me and everyone more else more info.

The information as fas as I am aware is seismic, in that it relates to what it would register on the richter scale, and the depth of the activity

ie earthquake activity at the volcano, but as far as I have been led to believe in the past, indicators of an iminent eruption would be earthquake swarms, meaning lots, best person to explain this would be puterman or trueamerican I'm sure

Using the first reading on the KIkai Caldera

you have the figures 4.2 and 100km, this equates to a 4.2 magtitude quake at a depth of 100km underground, at least this is how I understood it to be interpreted.

This is why I said I found it disturbing that despite all the activity in Japan its amazing no quakes were reported from any of the above listed volcanoes, I wasn't trying to kill your thread, just pointing out the irony of their satus, which leads me think, are we being given all the info on this site (RSOE), or is it being held back ?

Good thread by the way, I did S+F

I wonder how accurate are these sites...can they be trusted?

It seems to be fairly accurate on everything from fish, bird kills, to outbreaks of hepatitis in restaurants.

I just noted they just now updated that Mt. Tambora had something just now. That is a bit spooky. Mount Tambora is the one that gave us the year of no summer back in 1815. Maybe a false alarm

The really disturbing part to me is that all the other Super Volcano's have no data at all. Makes you wonder why these have data and nothing else does.

I always have a soft spot for RSOE, becuase they used to have the volcanic explosivity index on there too, but for some reason it is no longer there, I don't know if it just doesn't exsist period anymore, or if somehow TPTB made them remove it ??? I have no idea, but what I do know is that I agree with OP, RSOE does seem to an accurate source for info, and the mass animal death section never exsisted before the Arkansas event at new year, so you know they take all these animal deaths seriously.

Wonder if tere is someone a little more in the know who can shed light on RSOE's accuracy and credtials.
