Expected Earthquake, Volcanic or Storm Activity Until Further Notice


Are YOU Prepared?

ORANGE ALERT: The stresses are continuing to grow again in the NE Pacific. Today's map shows stresses on the western end of the Murray Fracture Zone. There is an area of stress north of Hawaii which we see connected to the Murray Fracture Zone as well. Another area of potential seismic activity appears to be forming off the Monterey coast. However, it could be due to local storm activity.

For further implications of what this means, see the NCODA map of August 2.

Raw Data Map

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.

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.
