Expected Earthquake, Volcanic or Storm Activity for the Next 1 to 5 Days
Are YOU Prepared?
September 28, 2005
By Stan Deyo
The seismic stress signals shown on my maps do not always convert to an earthquake. However, by showing the stress signals of the previous 4 days along with the current signals the maps enable you to see where stresses are building and/or travelling over a 5-day period.
Japan: Kobe showing minor stress signal today... estimated 4.0 Richter.
USA: West Coast from Baja to Gorda Ridge (Southern Juan de Fuca) showing continuing stresses.
Central America/Mexico: Three seismic stress signals from panama to Southern Mexico... small strengths less than 4.0 Richter.
French Guiana: Showing stress signal off the coast... estimated 5.0 Richter.
South Western Africa: Madagascar showing signs... estimated at 4.0 Richter.
The worst place for seismic stresses over the last 5 days is easily from Panama to Washington State along the western Ring of Fire. Japan has also shown consistent seismic signals for the last 5 days.
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 the oldest ones. White circles are Stan's prediction zones for today. Tomorrow these white circles will become light pink and will get darker as each day passes until they are removed.
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.
