Yesterday was an epic day for automated event detection throughout Central America.
Over the years, Angel and I have installed SeisComP’s at nearly every geophysical institute from Southern Mexico to the Colombian border. We spend a lot of time with clients tuning their SeisComPs to ensure that in the moment of truth, performance is top notch. The moment of truth struck yesterday when a Mw 6.8 earthquake (later revised down to Mw 6.6) sent network saturating waves from its epicenter south of Panama City through Central and South America:
We were excited to see that all SeisComP systems nailed the event location and magnitude, providing the region with solutions before the USGS and Geofon manually reviewed solutions were published/ emailed:
Institution | Magnitude (Mw) | First Location Time | Automatic or Manual
OSOP’s Principal Server | 6.7 | 1 minute 24 seconds!!!!!!!! | Automatic
University of Panama | 6.9 | 1 minute 51 seconds!!!!!!!! | Automatic
Panama Canal | 7.0 | 3 minutes 27 seconds | Automatic
Client 1 | 6.6 | 3 minutes 38 seconds | Automatic
Client 2 | 6.8 | 3 minutes 27 seconds | Automatic
Client 3 | 6.7 | 3 minutes 34 seconds | Automatic
Client 4 | 6.6 | 3 minutes 45 seconds | Automatic
GFZ | 6.6 | n/a | Manual
USGS | 6.6 | n/a | Manual
CSEM-EMSC | 6.7 | n/a | Manual
Notice the amazing first location timing at OSOP and UPA compared to the ACP and Clients 1 –> 4. Why the difference? Station density. Plain and simple. For the price of a single broad band installation the Panamanian government contracted OSOP to install a dense network of 75+ short period sensors to complement the broad band network. This has dramatically improved first location times and has reduced the magnitude of completion for the event catalog. The ACP’s system has full access to the Panama broad band network but has not yet integrated the new network of short period sensors.
OK, back to the electronic’s lab…hasta Friday 😉
