Quick hits to wrap up the week:

• Following up some news about Changbaishan/Changbai caldera in North Korea, Yang Qingfu, director of earthquake and volcano analysis and forecast center with the seismology bureau of northeast China’s Jilin Province, says that the volcano appears to be quiet and that there are no signs of an impending eruption – at least not in the next dozen years. The bigger news (in my mind) is that China will be installing full monitoring (gravity, deformation, electromagnetics, fluid monitor and seismic) to watch the caldera that last erupted in 1903.

• I’ve been getting a number of emails and tweets about seismicity around our friend Katla over the last 24 hours. Again, I am no expert on seismicity at Katla, but most of of the current earthquakes are very shallow (1 km or less), small (most Eyjafjallajökull bigger sibling.

• In the “File Under Lets-Worry-About-It-Now” folder, many people are suddenly jumping at the chance to buy volcano-specific travel insurance after the massive flight disruptions caused by Eyjafjallajökull. Now, I am not one to criticize proper planning, but I also find it interesting that a threat that was always there suddenly seems like a “new” thing. I mean, most people don’t buy travel insurance for flights during hurricane season … but maybe I am wrong. However, the insurance companies must be happy (for now).

• There are also especially nice views of the lava lake in the Haleuma`uma`u Crater at Kilauea from the HVO webcam. Apparently the lava lake has been surprisingly steady over the summer so far – but we’ll see how long that lasts.
