About Our Network

The BUET Low-Cost Accelerometer Seismic Network (BLCASN) is a group of BLCAs installed across Bangladesh to measure ground shaking during earthquakes. The network helps researchers and the public access reliable earthquake information quickly and easily.

Our network consists of strategically placed BLCA stations across the country, continuously monitoring seismic activity 24/7. We integrate data from local stations with international sources like USGS and EMSC to provide the most accurate and up-to-date earthquake information.
