Hi Brian -- that image is from a slide collection. We'll see if we can find the slide, and re-scan it at a higher resolution.

Hi Michael, I've fixed the webicorder images, so they should be displaying again (for volcanoes where the network actually is working). We have people out in the aleutians right now working on some networks, so hopefully we'll be able to get few back online. As far as Wrangell goes, there's no plans this summer to get it working again, hopefully in the next couple of years or so. Thanks, -Seth -------- Michael Fleming wrote: I have noticed most of the webicorders on this site no longer work. Does AVO have plans to get them working again, or is it a funding problem? I noticed you dropped Wrangell completely, do you have any plans to reactivate the seismograph at that volcano? -- Seth Snedigar Alaska Volcano Observatory Alaska Division of Geological and Geophysical Surveys seth.snedigar(a)alaska.gov 907-451-5033 http://www.avo.alaska.edu/

Re: Two quick questions from the Redoubt report

Hello Josh - I'll take a stab at your questions. 1). AVO was formed in 1988. Prior to AVO's formation, there were two seismic stations at Redoubt. When AVO was formed, instrumenting Redoubt was a high priority because of its eruptive frequency and proximity to Anchorage. So three more stations were added in October, 1989. 2). The webicorder plots actually come from VALVE - and likely we could give users more than just a .jpg, but it would be incredibly taxing to our servers and limited bandwidth. All of our seismic data is publicly available in near-real-time at IRIS, however - so you could download it from there and use your own tools for visualization and analysis. 3). Sadly, no, the public lectures aren't able to be streamed online. Judy Fierstein's April talk on Novarupta 1912 is available here, however: https://www.avo.alaska.edu/Katmai2012/videos.php Thanks for your interest! -Cheryl -------- Josh Ridderhoff wrote: Hello, I just finished reading through the report on the 2009 Redoubt eruption, and a couple of questions came up for me that I was hoping someone might be able to shed some light on. Nothing earth-shattering, just curiosities mainly: 1) It was mentioned that seismic monitoring equipment had been installed at Redoubt just a few months prior to the '89 eruption, but also that there wasn't any notable seismic activity until about 24 hours prior to the eruption. Was it just an incredible coincidence that the monitoring stations happened to get installed when they did, or had there been other clues going on that indicated there might be an imminent need for seismic monitoring? 2) Reading about SWARM, it sounds fairly plausible that it's this software that generates the webicorder images. Is that the case? If so, I noticed that SWARM allows for the user to zoom, filter, etc. on individual waveforms to get more detail, and I was curious to see if anybody has ever looked at expanding some similar functionality to the webicorder displays to give web users the ability to get better resolution for events of interest? Thanks for the time! P.S. -- I'm assuming not, but do you know if any of the public lectures this summer are streamed/recorded and available online? It's a tad cost-prohibitive to jet up to Anchorage from Utah for a day, but I sure wish I could be there to see a few of them (this week's especially sounds amazing)!

Thanks for the well-wishes! Today is a particularly windy day out in the Aleutians - a lot of wind noise on the stations out there. -Cheryl -------- GinnieÃÂ´Gidlund wrote: Congraulations to beeing able to start testing the wibicirders.

Re: volcano activity and moon position

Hello Barry - Here is one article that discuss what you're interested in: http://vulcan.wr.usgs.gov/Outreach/AboutVolcanoes/do_tides_affect_volcanoes… Some volcanoes (like Pavlof) seem more affected than others. But in all volcanoes, the effect appears very small. Thanks, Cheryl -------- Barry Willis wrote: Sirs, I live in Hawaii--home of Kilauea. I have a theory that the moon's position affects the activity of the active lava. So, the closer the moon, the more influence on the lava and therefore the eruption potential. I can't find any study or discussion on this. So what I expect is that IF an eruption were to happen, it would be when the moon is closest to the earth (high tide, of course). Can you direct me to a source of information for this topic or answer it?

Re: Mt Redoubt viewing/visit

Hello Padee - I think your view of Redoubt will be more weather-dependent than location-dependent on the Kenai. Helicopters and fixed-wing each come with their own sets of advantages and disadvantages. Probably the best thing for you to do would be to chat with the air-taxi services on the Kenai - they are used to doing "volcano air tours" for people. Lake Clark National Park has a page here: http://www.nps.gov/lacl/planyourvisit/directions.htm Thanks, Cheryl -------- Padee McCrery wrote: Hello again wonderful folks. I am making a trip to Alaska again this Sept. I am looking for ideas on how to best view/visit Redoubt... I want to stay where I can also have a good view (if not raining) Would like to fly by or visit. Is it best by helicopter of airplane. What are the options. Is it best in Kenai, Kasilof Clam Gultch? or how to visit lake Clark? I know you arent tour companies, so sorry if I am out of line in asking. thanks for all your work and camera shots and updates.. best always, Padee McCrery -- Cheryl Cameron Geologist, Alaska Volcano Observatory Alaska Division of Geological & Geophysical Surveys voice: 907-451-5012 fax: 907-451-5050
