## Description

Earthquake Alert is a powerful Chrome extension designed to detect earthquakes using your device's sensors. It provides instant information on earthquake type and magnitude while emitting alarm signals for immediate warnings. Users benefit from a real-time alert network linking friends for early quake notifications, offering crucial extra seconds before the quake arrives.

Key features include an ultrasonic frequency alarm audible to animals and rescue dogs, a home screen display with epicenter magnitude and perceptible intensity based on distance, and a dedicated widget control panel. The extension employs a self-learning system to adapt sensor sensitivity and filter minor movements, ensuring accurate alerts. Users can also review all recorded earthquake events with ease through an integrated list.
