earthquake-notifier

Serverless solution based on Lambda (in Rust), EventBridge and SNS to monitor for earthquakes and send email notifications.

Under the hood, it uses INGV APIs and scans them every hour.

Requirements

AWS SAM version 1.76.0 (or higher)
Rust
Cargo Lambda
Docker (required by SAM)
An AWS account and the AWS CLI installed and configured

Configuration

This solution can be configured to monitor a specific point on Earth for nearby earthquakes.

This is the list of configuration parameters that you can provide to customise it to your needs:

PrefixParam: A stack prefix used to name resources (default: earthquake-notifier)
EventBusNameParam: The name of the EventBridge bus to use (default: default)
CenterLatLonParam: Point to monitor for close earthquakes. LatLon format (default: 37.5079,15.0830)
MinMagnitudeParam: A float representing the minimum magnitude to alert on (default: 3.5)
MaxDistanceMetersParam: The max distance from the center in meters to monitor for (default: 2000000)
EmailAddressParam: The email address to subscribe to for notifications

Build and deployment

To build and deploy:

sam build --beta-features
sam deploy --guided

Note: the flag --beta-features is currently required for the integration with cargo-lambda. More info here.

If all goes well, now you should have a lambda running every hour on your account to check for recent earthquakes and notify you if one of them matches your conditions.

EventBridge events

Since this solution emits new EventBridge events every time a new earthquake is detected, you could create additional integrations on top of that.

This is a sample event that will be generated:

{
  "version": "0",
  "id": "83a2ecd4-004b-bf82-3d66-be3f7ff7fc62",
  "detail-type": "earthquake",
  "source": "earthquake-notifier",
  "account": "795006566846",

    "event_type": "earthquake",
    "latitude": 39.6948,
    "longitude": 16.0648,
    "mag_author": "--",
    "mag_type": "ML",
    "magnitude": 3.8,

    "url": "http://terremoti.ingv.it/en/event/34328071"
  }
}

Local Development

You can start a local development server with:

cargo lambda watch

Then, in another terminal run the following command to trigger an event (and invoke your local lambda):

cargo lambda invoke --data-file events/schedule.json earthquake-notifier

You should see logs in the first process and the result of the lambda execution in the second process.
