Potential Russian eruption closes airport

News is filtering in that Koryak (aka Koryaksky) Volcano in Kamchatka might be heading towards an explosive eruption. The details are scarce, but it seems that a breach on the northwest slopes of the volcano might cause an explosive eruption, however, it is not clear why this is. All this talk has caused the Petropavlosvk-Kamchatsky Airport (~13 miles northeast) to close in fears of this potential activity.

Koryak is yet another potentially active volcano on the Kamchatka Peninsula, along with currently active Bezymianny, Kliuchevskoi, Karymsky and Shiveluch. The last eruption at Koryak was in 1956-57 that produced pyroclastic flows and lahars, a VEI of ~3 event. Beyond that, there isn't too much known about the volcano's past activity.

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…

More accurately, the recent pictures at the top of the page that I linked to in my above comment, shows a mixture of steam and ash.

The several pictures from yesterday don't capture the reported 4km high ejection of ash - but do show an increase in ash. The pictures could have been taken before - or perhaps after the dispersal of the ash ejection.

Between me and my husband we've owned more MP3 players over the years than I can count, including Sansas, iRivers, iPods (classic & touch), the Ibiza Rhapsody, etc. But, the last few years I've settled down to one line of players. Why? Because I was happy to discover how well-designed and fun to use the underappreciated (and widely mocked) Zunes are.

Thing you are talking about sounds right. Nonetheless, think about this, let's suppose you integrated a little more? What i'm saying is, I dont tend to tell you ways to write your blog, but if you actually added extra content that can easily get peoples focus? Simply like a video or perhaps a snapshot or perhaps two to have viewers excited about what you are talking about.

This is a good approach to what, for some, may be a controversial topic. Very well though out post. - I am dying from the treatment of too many physicians. - Alexander the Great
