Help (Java-based Form)

This form is used for sending user defined values for selection from Seismological Catalog. Client software consists of Java-based request form as well as simple HTML form. While Java-based form provides more convenience, especially if user needs to define complicated area form, it can't work under old WWW browsers which do not support Java. In this case user can use HTML form, which, being less convenient, provide the same level of functionality.

  1. Select map orientation: Map1 or Map2.

  2. Define form of area for search.

    1. Rectangle. Move cursor to one of proposed corners of rectangle, press mouse key, draw mouse to the opposite corner, then release it. You can start from any of the corners.

    2. Polygon. Move mouse to the first corner (node) of proposed polygon, click mouse, then move it to the next (incident) node, again click, and so on. Press together two mouse buttons to close polygon.
      By default maximum number of polygon nodes is 50.

    3. Circle. Move cursor to the center of circle, press mouse key, draw mouse along the radius to the circle and press mouse key.
      Note that the circle is not actually round one because of map projection used.

    4. Coordinates. In this case you don't need to draw anything on the map. Change coordinate fields of the form if you need.

  3. Fill in text fields of the forms for time , magnitude and depth intervals.
    When you filling in text fields of the form applet prevents you from entering non-digit characters or interval delimiter, if it is not applicable. In case of entering values, which are out of the default range, a warning message appears.

  4. Redrawing and changing. To redraw figure and change it or to change time, magnitude, and depth values press "RESET" button.

  5. Submit. When your request is ready press "SUBMIT" button to submit entered data to the server.
