Expected Global Earthquake, Volcanic or
Storm Activity for the Next 1 to 5 Days;
(Except the SW Pacific and Indonesian Ocean
Which Have a 1 to 10 Day Window)
Stan's analyses often show seismic stress signals that do not become full-fledged earthquakes in his 5 to 10 day forecasts. He has maintained for a number of years that these signals indicate pressure build-ups which are just as important as actual earthquakes in long-range regional threat assessments.
Recently, geologists have identified a seismic event they call a "slow earthquake." (see Silent Earthquakes Might Predict Major Events and Kilauea's Sides Undergoing 'Slow Quakes'). It might be that these slow earthquakes are connected to seismic signals that don't appear to make a normal earthquake in Stan's 5 to 10 forecasts.

East of Maryland: There are small intense thermal anomalies in the sea. These may be due to excessive speed in the Gulf Stream.... but they look like the same signal I would expect before an earthquake.
Gulf of Mexico: showing signs of a small seismic buildup close to the area of the Richter 6 quake a few weeks ago.
San Francisco Region: ALERT.... There is a seismic precursor signal forming between the Mendocino and Pioneer Fracture zones leading into San Francisco. This is NOT a good area to see stresses building. I advise caution and emergency preparedness for the next week. See map immediately below.
West of Hawaii: a small seismic stress area is forming.
North of Bouganville, PNG region: I have also posted an unusual heat patter about 500 miles north of Bouganville. I believe this may be an undersea volcano warming up. See map on left.Stan Deyo
ENCODA MAPS follow below.
For an explanation of how these maps are produced, please see this area.
Stan's analysis shows areas of possible earthquake or volcanic activity, or extreme storm conditions for the next 1 to 5 days. Pay particular attention to areas marked by white circles. The continuous yellow line denotes plate tectonic boundaries as well as the Ring of Fire. Go to the raw data map where it is easier to see the areas of concern. Go to Stan's earthquake map archives.
NEW FEATURE: The circles in varying shades of red are quake prediction zones Stan made from 1 to 4 days ago - with dark red being 1 day ago and the lightest red being 4 days ago. White circles are Stan's prediction zones for today. Tomorrow these white circles will become dark red and will get lighter as each day passes until they are removed.
These circles indicate the stresses in an area and warn of a probable quake in an area. The areas do not always convert to a quake. When a quake does occur and has been in or fairly close to the outer radius of a circle I have drawn over a given fault zone area then it is counted as a "hit". When stress signals go into a large land mass I have to estimate the radius of the circle and the vector to the nearest major fault on the land mass.
DEYO NOTES: For earthquake maps, see the USGS "shake maps" (click anywhere on the global map for a closer view). For quakes USGS may not list, go to the European-Mediterranean Seismological Center's map and scroll to the bottom of the page for a global view. You can compare these maps for the next 5 days to Stan's NCODA maps, to see the hits of his seismic target zones (white circles).
Earthquake lists can viewed at EMCS and at USGS.
Ecuador's Geophysics Institute at the National Polytechnic School, does not list quakes on a daily basis as does the USGS and other entities, but when there are significant events, they post them in PDFs.
Disclaimer: Some of the forecast stress areas can be in error up to 30% due to cloud cover variations and false signals from buoys.
