Sorry for the lack of updates recently - I can't make any excuse other than my laziness, really. I could claim that my laziness is brought on by the heat here, I guess, which is probably true...

Anyway, the first of two posts will be a quick collection of photos from IAVCEI 2013 and my visit to Sakurajima Volcano Research Center (where all of my data comes from!).

Kagoshima is definitely a city well-prepared.

The people are so complacent - Sakurajima erupts again, life continues...

IAVCEI 2013 conference hall (the main one, anyway).


My office away from home!

An array of very old (but still functioning) smoke-drum seismometers.

Modern seismometers - or at least, where their data is received.
These detect earthquakes and tremor within and near the volcano.

The central system which receives and processes all seismic
(earthquake) and ground deformation data.

Old recording equipment at the Harutayama field observatory.
The blue box is a CO2 monitor telling us if it is safe to enter the tunnel

The Harutayama tunnel, containing an array of ground deformation sensors
(tilt and strain). These tell us if the volcano is changing shape, usually due to
magma or gases moving around inside.

Broadband seismometers and a borehole tiltmeter in the
Harutayama tunnel.

GPS (also detects ground deformation) and weather observation
station at Harutayama.

A very, very old smoke-drum seismometer (still working!).

An original smoke-drum barometer - this has since been replaced by
electronic equipment but also still works. It detects changes in air
pressure, such as shock waves caused by volcanic explosions.

Cloudy view of the summit region from Harutayama observatory
(about 400m elevation - the summit is about 1100m).
