A pile of news for the new week! The glow of new lava flows from Nyamuragira in the Congo, taken from the Virunga Park Headquarters, January 2, 2010. Mayon PHIVOLCS may lower the alert status at Mayon to Level 2 after almost a week of lower seismicity and no ash explosions since December 29th. Schools…

It’s the last week of classes and it’s also AGU (which I will be missing for the first time in 5 years). If you happen to be at the big meeting in SF and hear something you think we’d like to hear, feel free to drop me a line or leave a comment so we…

Its already Friday! News! Print of the Temple of Jupiter at Pompeii with a steaming Vesuvius in the background. You can now wander down the streets of ancient Pompeii from the comfort of your own home or office. Google Streetview now cover the streets of the city wiped out by the 79 A.D. eruption of…

Before we get to the latest SI/USGS Weekly Volcanic Activity Report (WVAR), I wanted to draw your attention to some nifty NASA Earth Observatory images from the current activity at Soufriere Hills in Montserrat. After a few puffs last week, the volcano is now releasing a relatively constant stream of ash and steam, this after…

Friday Flotsam

Pohutu Geyser in Rotorua, New Zealand. Image taken by Erik Klemetti in January 2009. 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,…

How volcanoes affect the economy

Photos by Dr. Edward Kohut, all rights reserved, used by permission, 2009 Many times people think that volcanic eruptions affect the economy through the destruction inflicted upon the landscape during an eruption: lahars and pyroclastic flows destroying bridges and homes, ash ruining crops and water, lava flows overunning communities. However, in Hawai’i, a new effect…

Lava keeps flowing at Kilauea

Although this news isn’t as threatening as the title of the article implies: HAWAII LAVA FLOW NEARS NATIONAL PARK, it is still some news as it could be the first lava flow to cross into the park in over a lava. The flow itself is headed towards what is called the “Waikupanaha ocean entry” on the…

Kilauea’s new fire fountain

  Kilauea is busy keeping geologists and tourists alike wondering what the volcano will be doing next. The current report on the volcano tells of a new fire fountain at the Thanksgiving Eve Break-out “rootless cone”, about 6 miles from the ocean. The fire fountain started on Sunday night, issuing lava up to 40 feet in…

Hawaiian Vog

The latest eruption at Kilauea has increased the amount of vog on the big island of Hawai’i. Vog is more or less the same as the anthropogenic “smog” produced by car/industrial exhaust, but produced by volcanic gases (carbon dioxide, carbon monoxide, sulfur dioxide, hydrogen sulfide amongst others). It definitely doesn’t make for good air quality,…
