One of the writing assignments I always enjoyed in high school was the “compare and contrast”. You could sit back and look for stylistic differences between writers and texts –…

On the media (or press)

It seems like I’ve been stepping on a lot of people’s toes lately, so in an effort to foster more camaraderie and less belligerence between the “old media” (this is not derogatory, but rather refers to anything pre-internet news source or classic journalistic source) and “new media” (this includes internet-era news sources, bloggers and the…

The rifting of Africa

Lava flows from the 2005 Mando Hararo eruption in Ethiopia. Alright, I had been attempting to ignore this story because it was, well, a little uninteresting at first, but it apparently has legs so I will tackle it. Slashdot has a post proclaiming: ‘Volcanic activity may split the African continent in two, creating a new…

There have been a number of articles floating around the popular press for the last week that I thought I would touch on briefly … always fun to decipher the real news from the hype. Active fumaroles on Datun Mountain in Taipei. An article out of the Taipei Times suggests that the city of Taipei…

The Atherton Tablelands in Far North Queensland, Australia. Nothing makes me shudder like any article titled “Blankety-blank volcano is overdue”. Typically the article that follows is full of nothing but vapid speculation and media fear-mongering. So, it wasn’t too surprising that an article titled “Volcano eruption ‘overdue’” in the Brisbane Times (amongst many other sites)…

What might be happening at Mt. Rainier?

Eruptions reader Doug pointed out in a recent comment that the seismicity at Mt. Rainier in Washington has increased over the last month or so. Take a look for yourself: Mt. Rainier seismicity over the last year (8/2008 to 9/2009). Image courtesy of PNSN Taking a closer look, over the last week there has been…

Large eruption underway at Shiveluch

Undated photo of Shiveluch volcano in Russia. In case you haven’t seen the report yet, Shiveluch in Kamchatka has gone, as they say, “non-linear”. KVERT has raised the alert level at the volcano to “Red” with reports of many strong explosions and an ash plume of >32,800 feet / >10 km. This all suggests that…

Lets get right to it! “Manmade volcanoes”: can they solve global warming? It does indeed seem that something is happening beneath Kanlaon in the Philippines. PHIVOLCS reports that the volcano experienced 257 volcanic earthquakes from August 23 to September 1, well above the usually “background” level of ~20-30 a week. Most of this seismicity is…

Eruption occuring on Venus?

Quick hit post from beautiful Walnut, Iowa, but this was too interesting to pass up… Bright plume spotted on Venus, image taken by the ESA Venus Express. Did a volcanic eruption recently occur on Venus? No one really knows, but a bright plume of unknown material was spotted by an amateur astronomer. One possible source…

Is something up at Shishaldin?

Shishaldin volcano in Alaska. Yesterday I mentioned in the SI/USGS Weekly Report update that things appear to be afoot at Shishaldin in the Aleutians. Well, I checked the Shishaldin webicorder today and indeed, [SPECULATION] something seems suspect. Now, the increasing signal might be wholly unrelated to any magmatic activity, but it is interesting to see…
