Earthquakes Monitoring and Sharing Data in Real Time in Baja California

• Baja California is located in the tectonic border of the Pacific and the North America plates.

• This region is tectonically active and generates seismic activity continuously.

• This region is capable of generates moderate to big earthquakes that could be dangerous to populated region

BAJA CALIFORNIA:

The 7.2 (Mw) magnitude El Mayor Cucapah earthquake of April 4 of 2010, evidence the lack of a well instrumented and dense seismic network in the region that could prevent the local and federal Mexican authorities from rapidly assessing the impact of the quake and its effects on the peoples and infrastructures.

After the bigger earthquake never recorded in Baja

What have we done?Instrumentation of 42 new seismic stations in the region of Mexicali Valley, Mexicali and Tijuana cities connected to CICESE in real time by internet.

23 accelerometers stations, 5 in Tijuana and 18 in Mexicali.26 Broadband and accelerometer seismic stations in the Mexicali Valley and in the Baja California state.

Agreements of collaboration with Caltech-USGS-CENAPRED-CICESE to monitor and share seismic data in real time.

We know were the earthquakes occurs … but no when.

That why we need to be monitoring 24/7 the seismic activity to observe any change in the seismic activity behavior.

¿What next…?

¿How we can do this:

1. radio?2. Telephone?3. Commercial Internet?4. Satellite internet?

Each red star is a 6 channel (3 acceleration, 3 BB velocity) seismic station, 100 sps, 24 bits resolution.

Monitoring the seismic activity in real time to inform the local, state and federal authorities about the earthquakes with relevant magnitude that are occurring in the region.

¿Services… seismic report and seismic alert in real time ?

Automatic earthquake location and magnitude, 5 minutes after the occurrence.Earthquake information by SMS and WEB pages to people, media and authorities.Earthquake higher intensities recorded, 30 minutes after the earthquake and the intensities distribution maps (Shake Maps).Sharing seismic data with SSN, SCSN-Caltech and others…

EarthquakeOrigen time

Seek for a safe place

Wave propagation

Information flow

Earthquake analysis

Seismic monitoring and its objetive…

That mean sharing scientific data…

CICESE and USGS will deploy an information-sharing system to be better prepared when a seismic event occurs.

This implies transferring very large volumes of data among these institutions – on the order of hundreds of Gigabytes. (Middle of 2013) 9

Big Data and Network Link

This will allow the implementation of high performance cyber infrastructure for research and development.Establish new ways to collaborate and sharing knowledge in USA and Mexico countries.It also represent challenges in order to find new ways of sharing information.
