M9.2 Earthquake
|
Repeat of 1964 M9.2 Earthquake. |
March 27 10:10:15 AM AKDT (OT+15 seconds)
|
Pd rapid earthquake magnitude |
Rapid earthquake magnitude based on maximum seismic P wave amplitude at 4 closest real-time GPS stations with accelerometers. Used for early warning of strong shaking from shear waves. Provided by Univ. Washington.
|
March 27 10:11:25 AM AKDT (OT+85 seconds)
|
PGD magnitude update |
Rapid earthquake magnitude based on peak ground displacement at 4 closest GPS stations with accelerometers. Provided by Univ. Washington. |
March 27 10:12:30 AM AKDT (OT+ 2.5 minutes) |
FastCMT |
Rapid model of the earthquake, based on near-field GPS and seismic stations and using fastCMT software, and used to generate many tsunami products. Provided by SOPAC group.
(Example from Tohoku)
|
March 27 10:40:00 AM
AKDT (OT+ 3 minutes to 30 minutes)
|
Near Source Tsunami Height & Runup |
Map of tsunami height and runup (maximum water elevations on land) at the coastline adjacent to the earthquake from real-time GPS stations with accelerometers. Key update at 30 minutes incorporating data from near-shore wave buoys and ocean-bottom pressure sensors. Provided by SOPAC. (Example from Tohoku) |
March 27 10:15:00 AM AKDT (OT+ 5 minutes)
|
Tsunami Source Model |
Model of tsunami source derived from real-time GPS, delivered to NOAA for use in accurate predictions of wave arrival times and inundation maps. Provided by JPL Tsunami Group. |
March 27 10:18:00 AM AKDT (OT+ 8 minutes) |
Tsunami Wave Height Prediction (20 min and 90 min) |
Estimates of tsunami wave heights at 20 minutes and 90 minutes after the earthquake based on Tsunami Source Model. Provided by JPL Tsunami Group |
March 27 10:20:00 AM AKDT (OT+ 10 minutes) |
Tsunami Arrival Time Prediction |
Estimate of tsunami arrival time based on GPS observations of changes in the ionosphere caused by tsunami waves. Provided by JPL Ionosphere Group. |
March 27 10:20:00 AM AKDT (OT+ 10 minutes) |
Tilt/Vertical Change Map |
Tilt is the change of slope that can affect water distribution, drainage, and sewage services. These maps are generated from model based on initial earthquake information. Provided by JPL E-DECIDER. |
March 27 10:20:00 AM AKDT (OT+ 10 minutes)
|
Strain Magnitude Map |
Deformation strain magnitude can identify locations of potential fault surface rupture as well as locations where infrastructure may be dangerously stressed by tension, compression, or shear of the surface materials. These maps are generated from model based on initial earthquake information. Provided by JPL E-DECIDER. |
March 27 10:20:00 AM AKDT (OT+ 10 minutes)
|
Aftershock Forecast
|
ETAS type forecast based on aftershock scaling relations intended to provide estimates of aftershock activity following a large mainshock. Provided by JPL E-DECIDER.
|
March 27 10:25:00 AM AKDT (OT+ 15 minutes) |
Horizontal and Vertical Movement Maps |
Permanent horizontal and vertical movement caused by the earthquake, useful for identifying areas that have been disrupted by large ground movements, for example coastlines that have uplifted or dropped down by several meters. These maps are based on real-time GPS observations. Provided by JPL ARIA. |
Anytime |
Infrastructure Database Service |
Service for providing map layers that can be used to locate and identify critical assets that may have been exposed to damage after an earthquake, such as dams, freeway bridges, schools, police and fire stations, hospitals and other high priority targets. Provided by JPL E-DECIDER. |
March 27 12:30:00 PM AKDT (OT + 2.5 hrs)
|
Tsunami Arrival Time Prediction Update |
Predicted arrival times at major metropolitan areas in the West Coast. Delta time will be at every 10 minutes. Based on GPS-detected perturbations in the ionosphere generated by tsunami waves. Provided by JPL Ionosphere Group. |
March 28 10:00 AM AKDT (OT + 1 day)
|
Damage Proxy Map |
Estimates of where the earthquake has caused significant damage caused by building collapse, tsunami inundation, landslides, and liquefaction. These maps are generated from satellite radar data. Provided by JPL ARIA.
|
March 28 10:00 AM AKDT (OT + 1 day) |
Damage Proxy Data Feed |
Data feed of geographical coordinates with descriptive text tags that have been identified using both the Damage Proxy Map and additional data layers, for example critical infrastructure maps, landslide probability maps or liquefaction probability maps. Provided by JPL ARIA.
