Early Earthquake Warning Saves Lives
Even a few seconds of warning can enable protective actions such as:
Public: Citizens, including schoolchildren, drop, cover, and hold on; turn off stoves, safely stop vehicles.
Businesses: Personnel move to safe locations, automated systems ensure elevators doors open, production lines are shut down, sensitive equipment is placed in a safe mode.
Medical services: Surgeons, dentists, and others stop delicate procedures.
Emergency responders: Open firehouse doors, personnel prepare and prioritize response decisions.
Power infrastructure: Protect power stations and grid facilities from strong shaking.
Concept: Early Earthquake Warning
Introduced by Alejandro Cantu, CEO of SkyAlert
A seismic network is deployed along the Pacific Coast, one of the seismic actives zones in Mexico. The network is composed of a set of sensors grouped by clusters, each cluster is located in different cities, each cluster can allocate from 1 to 5 sensors. Every time the system confirms an earthquake, the parameter MDACT changes from OFF to ON. Problem: Based on the database, determine the best way to notify the occurrence of an earthquake, taking into account: 1. One single station trigger 2. Multi-station trigger 3. Correlation between the seismic catalog and the sensors database. 4. Additionally, take into account that we want to sense and report medium to large magnitude earthquakes which are usually the ones that affect cities the most and avoid sensing/reporting small earthquakes. 5. Some of the earthquakes that were felt in Mexico City, determine a rule to notify those earthquakes.
