SI/USGS Weekly Volcano Activity Report for 8/19-25/2009

The slow summer for volcanic eruptions continue. Only 11 updates in this week's USGS/SI report. Thanks again to SI's Sally Kuhn Sennert for compiling the news!

Highlights this week include (not including Kilauea) include:

  • Tungurahua in Ecuador produced some minor lahars on August 21 to go with steam-and-gas emissions.
  • Popocatépetl in Mexico produced an ash plume that reached ~8.2 km / 27,000 feet on August 20 and continued to produce steam-and-ash plumes throughout the week following.
  • Over on the Kamchatka Peninsula, both Koryaksky and Shiveluch produced significant ash plumes (reaching 3-5 km / 10,000-15,000 feet) and seismicity remained elevated at both volcanoes.
  • Chaiten, Chile, remains active over 18 months since it started erupting in May of 2008. Steam-and-ash plumes continue to be produced from Domo Nuevo 1 and 2.

Anybody know when the GVP site will be back online? Erik?

Sorry Mike, no idea when it might be back up. I did notice it was quite slow over the weekend and now the front page has this splash:

"As many of you have noticed, the GVP website has been experiencing performance problems over the last week. The situation has continued to worsen, so we have taken the site off-line. We are working to get the website back in operation as soon as possible. Thank you for your patience. "

Hopefully they can get it straightened out!

The truth is statistically speaking they are both highly ineffective. A thing such as 97% of community marketers fail to accomplish any success. The primary reason for that is failure to take motion adopted by taking all of the incorrect actions. For exampleâ¦I often advise my prospects and down-line to not âsellâ anyone on their opportunity. Itâs a disservice to their situation and to your business. It costs way an excessive amount of moolah to persuade somebody to start their own company if they're not interested in no way mind the fact that to achieve success in community advertising campaigns you need to establish a successful downline. This usually means you need to find persons absolutely interested in starting their own business.
