| Outline of Final Research Achievements |
In the central cone of Aso volcano, Kyushu Japan, there are several basaltic activities of 3-5 ka in age. The lava flows from those cones spread on the northwestern flank of the central cones, and they were classified in the relation to the cones.
We have carried out the paleomagnetic direction measurements to draw the paleomagnetic secular variation curve (PSVC) of the duration to extend it back to pre-historic ages. The PSVC is exceptionally precise as it is from volcanic lavas, and it will help understanding the nature of the geomagnetic fluctuations.
The PSVC enabled us to assign the ages of each lavas in the sites. They require a revision of the classification of the lavas, and to alter the eruption mode from sporadical to continuous within the active duration.
