NOAA Pacific Tsunami Warning System, M7.0+ submarine earthquake triggers, and coastal inundation zones tracked live.
🧠 OPEN BRAIN DASHBOARD LIVEOn December 26, 2004, the Indian Ocean erupted. A magnitude 9.1 earthquake near Sumatra spawned waves that crossed 3,000 miles of open water and killed nearly a quarter-million people—most of them never saw it coming. Today, that catastrophe drives a global early-warning imperative. The difference between survival and tragedy often comes down to minutes—and knowing exactly when that wall of water will arrive at your coast.
The Tsunami Risk tab on Pandita Data's Brain Dashboard gives you those critical minutes. Real-time NOAA alerts, travel-time forecasts, and coastal inundation mapping transform raw seismic data into actionable intelligence for coastal communities worldwide.
Open the Tsunami module at panditadata.com/brain_dashboard and you're connected to the Pacific Tsunami Warning Center's live feed. Right now: 0 significant earthquakes globally, 0 tsunami-flagged events. But the system never sleeps.
Here's what the dashboard tracks in real time:
Tsunami waves don't travel like wind or rain. They're shallow-water gravity waves—their speed depends on ocean depth, not the earthquake's size. The formula is deceptively simple: wave speed = √(gravity × depth).
In shallow water near shore, friction and bathymetry slow the wave but compress and amplify it—a 1-meter ocean swell becomes a 30-meter wall. The Brain Dashboard uses GEBCO bathymetric data and historical wave-amplitude records to forecast this transformation in real time.
Not all earthquakes spawn tsunamis. Vertical seafloor displacement—the sudden uplift or subsidence that displaces water—is what matters. The PTWC uses magnitude 7.0 as the operational trigger because subduction-zone earthquakes at this threshold reliably displace enough water to create transoceanic waves. Smaller quakes rarely generate distant tsunamis; larger ones cascade into automated regional alerts.
The Brain Dashboard flags M7.0+ events within minutes of detection, then models wave arrival across all threatened coastlines. For Lima, Peru—surrounded by the Peru-Chile Trench subduction zone—this means tsunami watch status can activate within 15 minutes of rupture.
Right now, Lima shows green status: no active threat. But the region's proximity to one of Earth's most seismically active zones means that could change in seconds. That's why the Tsunami Risk module refreshes continuously, and why having that data at your fingertips isn't optional—it's survival.
