Why does the pattern of colors look like this?

Let’s check how reliable our travel time calculator and picks are#

To do this we will predict travel times across network for a few fixed source locations and compare against the observed picks.

    (i). First we'll do random source coordinates (and origin times)
    
    (ii). Then we'll do "known" USGS source coordinates (and origin times)

## Predict travel times (random source coordinatea and origin times)
n_srcs = 10 ## Number sources
t_win_rand = 10 ## Window over which sources occur (minutes)
src_random = np.random.rand(n_srcs,3)*scale_x + offset_x # (note: scale_x and offset_x define region of interest)
src_origin = np.random.rand(n_srcs)*60.0*t_win_rand + 12*3600.0 ## Nucleate sources within 10 minute interval, starting after 12:00:00 UTC.

print('Random sources')
print(src_random[:,0:2])
## This calls the travel time nueral network for chosen stations and sources

print('Shape of trv_out is (num_sources, num_stations, num_phase_type)')

Detected 487 number of initial local maxima

Let’s check, are these initial source locations reasonable? (note: not final answer)#

Note: these are the GNN predicted locations, not the association + travel time residual minimization locations.

These are also only detected over 3 hours (rather than the whole day)


## Plot sources
fig, ax = plt.subplots(figsize = [8,8])
plt.scatter(locs[:,1], locs[:,0], c = 'r', marker = '^')
plt.scatter(srcs_known[:,1], srcs_known[:,0], c = 'C0', s = 6.5, marker = 'o', label = 'USGS')
plt.scatter(srcs[:,1], srcs[:,0], c = 'C1', s = 6.5, marker = 'o', label = 'Ours')
ax.set_aspect(1.0/np.cos(np.pi*locs[:,0].mean()/180.0)) ## Set projection aspect ratio
d_pad = 0.5 ## Pad 0.5 degrees to plot axes
ax.set_xlim(np.array(ax.get_xlim()) + np.array([-d_pad, d_pad]))
ax.set_ylim(np.array(ax.get_ylim()) + np.array([-d_pad, d_pad]))
plt.legend()
plt.show(block = False)
print('How is quality? What are issues?')





How is quality? What are issues?





Now we’ll run the part of the GNN that predicts associations for these events, and then locates them with travel time residual minimization (will take a few ~minutes to run).#


## Run post processing detections.
print('check the thresh assoc %f'%thresh_assoc)

## Refine this

n_segment = 1
srcs_list = []
n_intervals = int(np.floor(srcs.shape[0]/n_segment))

for i in range(n_intervals):
    srcs_list.append(np.arange(n_segment) + i*n_segment)

if len(srcs_list) == 0:
    srcs_list.append(np.arange(srcs.shape[0]))
elif srcs_list[-1][-1] < (srcs.shape[0] - 1):
    srcs_list.append(np.arange(srcs_list[-1][-1] + 1, srcs.shape[0]))

## This section is memory intensive if lots of sources are detected.

How is quality? Is it improved? In what way?

Let’s now find “matched” earthquakes to the USGS events#

    (i). (i.e., events within a nearby spatial/temporal window)
    
    (ii). Can use the "maximum_bipartite_assignment" function in GENIE.
    
    (iii). Note: deteremining "matched" events is somewhat non-trivial (requires optimization)

temporal_win_match = 8.0 ## 8 s window match threshold
spatial_win_match = 30e3 ## 30 km match threshold

## First select only subset of "known" events within the time window we're processing (since we clipped the window to part of the day
ifind = np.where((srcs_known[:,3] > clip_win_start)*(srcs_known[:,3] < (clip_win_start + clip_win_duration)))[0]
srcs_known = srcs_known[ifind]
ifind_not_nan = np.where(np.isnan(srcs_trv[:,0]) == 0)[0]

matches1 = maximize_bipartite_assignment(srcs_known, srcs_refined, ftrns1, ftrns2, temporal_win = temporal_win_match, spatial_win = spatial_win_match, verbose = False)[0]
if len(ifind_not_nan) > 0:
    matches2 = maximize_bipartite_assignment(srcs_known, srcs_trv[ifind_not_nan], ftrns1, ftrns2, temporal_win = temporal_win_match, spatial_win = spatial_win_match, verbose = False)[0]
    matches2[:,1] = ifind_not_nan[matches2[:,1]]
else:
    matches2 = np.nan*np.zeros((0,2))
## matches1 and matches2 record the matched indices between USGS and detected initial events and travel time location events)

print('Matched %d events of %d USGS events'%(len(matches2), len(srcs_known)))
print('and detected %d additional new events (over %0.2f hr time interval)'%(len(srcs_trv) - len(srcs_known), clip_win_duration/3600.0))
      




Matched 71 events of 71 USGS events
and detected 265 additional new events (over 3.00 hr time interval)

We’ll now plot the matched earthquake origin time and spatial residuals#

Contents

Initialize#

Check Basic Network Files#

Now do remaining imports and initilizations#

Now let’s visualize the picks#

Let’s check how reliable our travel time calculator and picks are#

Is the travel time calculator working? Do the picks seem plausible? Why?#

Lastly let’s check the station and source graphs we’re using#

Now let’s run the associator. We’ll plot a few intermediate outputs and results.#

Let’s check, are these initial source locations reasonable? (note: not final answer)#

Now we’ll run the part of the GNN that predicts associations for these events, and then locates them with travel time residual minimization (will take a few ~minutes to run).#

Let’s now find “matched” earthquakes to the USGS events#

We’ll now plot the matched earthquake origin time and spatial residuals#
