@johnwalicki we only need 2 decimal places in the database for EEW purposes. By storing only 2 we protect the precise location of the sensor for privacy issues.

Send Node-RED alerts to IoT devices when an earthquake is detected

2

The first example in this repo listens for shaking from all the OpenEEW sensors in the EEW network. If a possible earthquake is detected it sends an alert via Twilio...

Create simulated sensor node using real accelerations

7

To help with testing it would be great to have a simple node that reads from a local file that contains sensor readings from a real earthquake, eg https://github.com/openeew/openeew-detection/tree/master/input/2018_7.2, and...

There's a terabyte of historical accelerometer sensor data. This OpenEEW dataset can be downloaded in 5 minute chunks and scanned to identify time periods of interest (earthquakes) Lets scan the...

The third dashboard in this repo plots the historical seismic activity from an OpenEEW dataset. It plots a 5 minute window. That's the size of the downloaded jsonl file. Sometimes...

Create a node-red-contrib-openeew package and STA/LTA node

1

Currently we are using a peak acceleration value to declare an earthquake. However any acceleration can trigger this (cars, people, drilling). Short term average/long term average (STA/LTA) is well used...
