Spatial Density - Locate the next volcanic event

Calculation options

Calculate a spatial density map (integrates to 1)
Calculate a spatial intensity map (integrates to the number of events)

Note: Multiple spatial intensity grids can be summed together if their map extents are equal.

Grid Boundries

Minimum and Maximum Easting (range: [200000..800000] meters)

Minimum and Maximum northing (range: [0..10000000] meters)

Grid Spacing

Input a grid spacing in meters (range: [10..10000] meters)

Bandwidth Options

0. Specify a smoothing distance in the X and Y directions (No SAMSE)
1. Use the automatic SAMSE bandwidth calculator (Yes SAMSE)

Plot Options (using WGS84 datum)

0. No plot - text data grid only
1. Quartile plot (degrees)
2. Log[output] plot (degrees)
3. Quartile plot (UTM/meters), specify UTM plot options below
4. Log[output] plot UTM/meters, specify UTM plot options below

UTM zone and hemisphere
(range: 1 - 60) Map

Map scale (cm per km)
If plot is too large, increase scale value

Tick Scale (sets number of annotations on axes)
Default is 10000m or 1 degree tick spacing
(10000m * TICK_SCALE) or (1 deg * TICK_SCALE)

Map Title
Default is no map title

Input Event Locations

2 numbers per line (easting northing), separated by a space.

Example:
54000 126000

Please be patient. Code execution may take up to 10s of minutes depending on the scale of your submission. A message will appear when the calculations are complete. Please leave this browser window open.
