Seismology on the rocks
=======================

Protocol
--------

Transcript from notes, I will add the figures explaining shot positions etc. later.

Times in local time

- 12:01 test shot 0 from altitude 40 cm
- 12:04 natural event
- 12:08:45 shot 1 30 m south of A3D on line through A3D and A3C
- 12:14 shot 2 60m on same line
- 12:19 shot 3 90m on same line
- 12:20 track 0 
- 12:21 natural event
- 12:24 track 1 from 30 m south perpendicular to line about 10 m track distance
- 12:24 track 2 same starting point about 33 m track distance
- 12:25 track 3 60 m track distance oposit starting at end of track 2
- 12:29 shot 4 (see figure)
- 12:31 shot 5
- 12:32 shot 6
- 12:33 shot 7
- 12:34 shot 8
- 12:37 track 4 from A3D to A3B
- 12:38 track 5 from A3B to A3D
- 12:42 *unreadable* gefühlter Crack
- 12:42 hammering, attempt to provoke crack
- 12:44
- 12:46 ice skater does circle around array
- 12:50 track 7 (see figure)
- 12:53 low frequency excitation (simulataneous up down movement of seismologists at A3A)
- 12:57 marching seismologists
- 13:00 forced crack driven through array

Cube files of A3C and A3D cannot yet be read with snuffler but data seems complete from file size, needs software fix!!!
