Friday Flotsam

It has been busy busy week for me, capped off today with a talk about my field work in New Zealand (see above), so I don't have much to say. Not much new news today about the Saudi Arabian earthquake swarms, but again, I'll keep my eyes pealed (incidentally, I still haven't been able to figure out why no western news sources have even mentioned the swarm).

Anyway, here's are some volcanic tidbits to enjoy over the long weekend:

  • Vog, as seen from space. Volcanic fog, fashionably shortened to "vog" is a real hazard in Hawai'i, damaging crops and lungs. The current shuttle mission (to repair Hubble), landing tomorrow, took some great images of Hawai'i, showing not only the vog on the island, but also the ocean entry of lavas from Kilauea.
  • In the bevy of Mt. Saint Helens anniversary articles this week, there were a couple that mentioned the new monitoring equipment being installed on the volcano. They are relatively inexpensive GPS units called "spiders". They do have a bit of Skynet in them as the spiders will have "computer-programmed "brains" can decide what some data means and which information is most important". However, they do seem to be about as state-of-the-art of any volcano monitoring I've ever seen. {Hat tip to Eruptions reader Richard Gardner for this news.}
  • The economic impact of the current activity at Redoubt is beginning to be felt in Alaska. The state figures it might be losing $1.5 million per month for the shutdown of Cook Inlet production due to the threat to the Drift River Oil Terminal. Meanwhile, AVO continues to wait for the big dome collapse that is likely to occur at the Alaskan volcano.

Here it is, my attempt to recap a year's worth of volcanic events. By no means is this supposed to capture every event, but rather the highlight/lowlights and what most captivated me during 2009. I'll be announcing the winner of the 2009 Pliny for Volcanic Event of the Year tomorrow. Waimangu…
Redoubt from Ninilchik, AK. Image courtesy of Calvin Hall. It has been a few days since we've talked about Redoubt. Well, it might be because the volcano has settled down for the past week, to the point that AVO put the volcano back to Orange/Watch status last week and hasn't had to go back to Red…
Redoubt seems to be setting its pattern for this part of the new eruptive period. There was another small explosion this morning that produced at 15,000 foot / 5,000 meter ash column that moved to the NNW. The seismicity has settled down since the early morning eruption today (3/25) as well. These…

hi Erik i found some info on Saudi Arabia

there not march info there but i give you a link and you can look it overe

all so Erik do you ues yahoo IM???

i think Long Valley has some in too do with all the quakes we been haveing down there in S CA

entral California Hit With 4.7 Magnitude Earthquake

KEELER, Calif. â A moderate earthquake has jolted an inland desert area in Central California.

The U.S. Geological survey says the 4.7-magnitude quake struck just before 4 p.m. on Saturday.

A preliminary report shows the quake was centered about seven miles southeast of Keeler, a small town in unincorporated Inyo County next to Owens Lake.

Several calls to the Inyo County Sheriffâs Department went unanswered.

it sould be noted that LA CA has been hit with a 4.7 follow by a 4.1 too days later the 4.7 was on sunday of last weekedend and the 4.1 was on tunday of last week and now here we are with yet other 4.7 on sat all in the same week

yeah, all these quakes are probably leading up to something. Long Valley has been active too, perhaps Mammoth will erupt

Erik do you think you can look in too this and find out whats going on???

IF the quakes are of volcanic origin -and it's a big if, tectonic quakes are hardly unknown in CA- the Inyo/Mono volcanic system, last confirmed activity <800 years ago, seems a more likely culprit than Long Valley itself. Be good to know the depth of the quakes as well as the epicenters, which is all that news reports usually give you

(message was cut off??) about to continue: ,800 years ago, would seem a more likely source than Long Valley. Be good to know the depth of the quakes rather than/as well as the epicenters

most of these earthquakes are near the Coso Volcanic field, south of Long Valley
