HERD is a research network in its earliest phase. Nothing on this page is a warning service. When stations come online, their raw data will be published openly — and this page becomes the live map the rest of the site talks about.
Where we honestly are
Hardware. The first station, Proto-1, is specified and costed: an ESP32-S3 with three BMP390 MEMS barometers, GPS time sync (PPS) and a 72-hour microSD buffer. The parts order for the first build (~$4k for the prototype run) is the current milestone — it has not been placed yet, and we'd rather tell you that than show a rendered fake. The build and the first 72-hour test run will be documented in the open journal.
The one question that decides everything. Before any mass deployment we test whether a network of cheap MEMS barometers can catch a real low-frequency event with an acceptable false-alarm rate. If it can't, we'll publish that too.
The planned Andaman coverage
- Surin — ~55 km offshore, the northern gate; first to hear a Sunda-Trench event.
- Similan — the western gate off Khao Lak, the coast 2004 hit hardest.
- Tarutao · Lipe — the southern gate, guarding the deep-south Andaman approach.
- Ko Ra · Phra Thong — the barrier islands shielding Khao Lak.
- Phuket — station #1 and the shore network the outposts report ahead of.
How this page fills up
Proto-1 built and listening
Order parts, build the first station in Phuket, run it for 72 hours straight. Its uptime and waveform snapshots appear here — the first real pixels on this map.
The first Andaman ring
The first batch of sensors along the Andaman coast, first cross-correlation data, methodology published, this page becomes a genuine live map.
10,000 stations · 5 countries
Thailand, Indonesia, the Philippines, Sri Lanka, India — dense rings around the volcanoes that matter.
100,000+ ears
Full Indian Ocean coverage, independent scientific validation, and candidacy for official warning infrastructure.
