To Signal(Old Version) Earthquake Signal (C) New Version When we watch past report, you will find future. We are reporting from Space Station Mars. It is the earth sky 4000km aroud the earth. If you can read Japanese, you will find Japanese version have more detail. Small red point on Satellite picture shows where need careful for earthquake. (ex.) We saw small red point on Aso Zan on 03/18.06:00 picture. 03/19 14:47 32.9N 131.1E 10k M2.8 (3 km from small red point) |

we can not take any responsibility at all. We permit only the one's that this point could be approved to see these. Low pressure stress information ( Announce a place where the strong low pressure stress happened.) Sunny after rain maybe need careful. Every 12 hour report! We maybe lose some stress information. We use another data, too. Information is below. (http://www.*********)After this URL introduction, it is hard to get picture. So we stop introduction of URL until computer response improve. |
