  Parse the finger site data.

  Parameters:
    `data` - Vector

### getEarthquakeData

    protected java.util.Vector getEarthquakeData()

  Get the earthquake data from the USGS. Should be called in a SwingWorker thread, or you will freeze the application.

  Returns the MapMouseListener object that handles the mouse events.

  Overrides:
    `getMapMouseListener` in class `OMGraphicHandlerLayer`
  Returns:
    the MapMouseListener for the layer, or null if none

### getMouseModeServiceList

    public java.lang.String[] getMouseModeServiceList()

  Return a list of the modes that are interesting to the MapMouseListener. The source MouseEvents will only get sent to the MapMouseListener if the mode is set to one that the listener is interested in. Layers interested in receiving events should register for receiving events in "select" mode: `

       return new String[] { SelectMouseMode.modeID };

  `

  ``
  Specified by:
    `getMouseModeServiceList` in interface `MapMouseListener`
  Returns:
    String[] of modeID's
  See Also:
    `NavMouseMode.modeID`, `SelectMouseMode.modeID`, `NullMouseMode.modeID`

### mousePressed

    public boolean mousePressed(java.awt.event.MouseEvent e)

  Invoked when a mouse button has been pressed on a component.

  Specified by:
    `mousePressed` in interface `MapMouseListener`
  Parameters:
    `e` - MouseEvent
  Returns:
    true if the listener was able to process the event.

### mouseReleased

    public boolean mouseReleased(java.awt.event.MouseEvent e)

  Invoked when a mouse button has been released on a component.

  Specified by:
    `mouseReleased` in interface `MapMouseListener`
  Parameters:
    `e` - MouseEvent
  Returns:
    true if the listener was able to process the event.

### mouseClicked

    public boolean mouseClicked(java.awt.event.MouseEvent e)

  Invoked when the mouse has been clicked on a component. The listener will receive this event if it successfully processed `mousePressed()`, or if no other listener processes the event. If the listener successfully processes mouseClicked(), then it will receive the next mouseClicked() notifications that have a click count greater than one.

  Specified by:
    `mouseClicked` in interface `MapMouseListener`
  Parameters:
    `e` - MouseEvent
  Returns:
    true if the listener was able to process the event.

### mouseEntered

    public void mouseEntered(java.awt.event.MouseEvent e)

  Invoked when the mouse enters a component.

  Specified by:
    `mouseEntered` in interface `MapMouseListener`
  Parameters:
    `e` - MouseEvent

### mouseExited

    public void mouseExited(java.awt.event.MouseEvent e)

  Invoked when the mouse exits a component.

  Specified by:
    `mouseExited` in interface `MapMouseListener`
  Parameters:
    `e` - MouseEvent

### mouseDragged

    public boolean mouseDragged(java.awt.event.MouseEvent e)

  Invoked when a mouse button is pressed on a component and then dragged. The listener will receive these events if it successfully processes mousePressed(), or if no other listener processes the event.

  Specified by:
    `mouseDragged` in interface `MapMouseListener`
  Parameters:
    `e` - MouseEvent
  Returns:
    true if the listener was able to process the event.

### mouseMoved

    public boolean mouseMoved(java.awt.event.MouseEvent e)

  Invoked when the mouse button has been moved on a component (with no buttons down).

  Specified by:
    `mouseMoved` in interface `MapMouseListener`
  Parameters:
    `e` - MouseEvent
  Returns:
    true if the listener was able to process the event.

### mouseMoved

    public void mouseMoved()

  Handle a mouse cursor moving without the button being pressed. This event is intended to tell the listener that there was a mouse movement, but that the event was consumed by another layer. This will allow a mouse listener to clean up actions that might have happened because of another motion event response.

  Specified by:
    `mouseMoved` in interface `MapMouseListener`

### setProperties

    public void setProperties(java.lang.String prefix,
                              java.util.Properties props)

  Set the properties of the EarthquakeLayer.

  Specified by:
    `setProperties` in interface `PropertyConsumer`
  Overrides:
    `setProperties` in class `OMGraphicHandlerLayer`
  Parameters:
    `prefix` - String
    `props` - Properties

### getProperties

    public java.util.Properties getProperties(java.util.Properties props)

  Get the associated properties object.

  Specified by:
    `getProperties` in interface `PropertyConsumer`
  Overrides:
    `getProperties` in class `OMGraphicHandlerLayer`

### getProperties

    public java.util.Properties getProperties(java.lang.String prefix,
                                              java.util.Properties props)

  Get the associated properties object. This method creates a Properties object if necessary and fills it with the relevant data for this layer. Relevant properties for EarthquakeLayers are the sites to retrieve earth quake data from, and the interval in milliseconds (see class description.)

### getPropertyInfo

    public java.util.Properties getPropertyInfo(java.util.Properties info)

  Supplies the propertiesInfo object associated with this EarthquakeLayer object. Contains the human readable describtions of the properties and the `initPropertiesProperty` (see Inspector class.)

  Specified by:
    `getPropertyInfo` in interface `PropertyConsumer`
  Overrides:
    `getPropertyInfo` in class `OMGraphicHandlerLayer`
