Tokyo magnetic dust after rain 14MAR2013
Collected by Dirk Ross, LunarMeteoriteHunter

We had rain 13/14 MAR 2013. On the early morning of 14th I went outside at 5'00 am and noticed an unusually large amount of  black/brown magnetic dust in the rain pools on concrete and have collected it. I don{t know if it is volcanic related, industrial, or run-of the-mill soil; but strange that this was accumulated after over 12 hours of heavy rain and within a 1-2 hour period just minutes ago. An area of 10cmX10cm yielded approximately 5gr of the dust.

Samples will be studied soon. It would be very interesting if this is not terrestrial.

Update- Late 14MAR2013

Sakurajima Volcano, Kyushu, Japan to Tokyo is approximately 900kms.

This MAY be the answer for the Tokyo magnetic dust containing mica?  Sakurajima volcano is approximately 900kms from Tokyo.

Sakurajima volcano (Kyushu, Japan): ash plume to 15,000 ft (4.5 km)
An unusually high ash plume rising to 15,000 ft (4.5 km) was reported this morning. This suggests a significantly larger than average vulcanian explosion took place.
