| Orientation of tension axis onto the horizontal plane. The length and width indicate the degree tha thte axis is horizontal. A vertical axis has zero length in the plot. Red color indicates recent events. The seismicity plot shows all earthquakes with M > 0 in the ANSS catalog from 1974/01/01 to 2003/12/31. |

| Orientation of pressure axis onto the horizontal plane. The length and width indicate the degree tha thte axis is horizontal. A vertical axis has zero length in the plot. Red color indicates recent events. The seismicity plot shows all earthquakes with M > 0 in the ANSS catalog from 1974/01/01 to 2003/12/31. |
| Orientation of pressure axis onto the horizontal plane. The length and width indicate the degree that the axis is horizontal. A vertical axis has zero length in the plot. Red color indicates recent events. The seismicity plot shows all earthquakes with M > 0 in the ANSS catalog from 1974/01/01 to 2003/12/31. |

Orientation of maximum horizontal compressive stress following the convention of Zoback (1992)
(Description of Stress Regime Assigment from WSM web page). Red indicates normal faulting, blue thrust faulting and green strike-slip faulting.
