Possible strong shake for South America / South Sandwich Islands

South-America, Central America/Caribbean? Probably not more than low to mid 6.

Emphasis possibly on Atlantic/Gibraltar/South Sandwich Islands.

We have high lunar geometry today (green peak index 12) following critical planetary geometry (red peaks), so be on watch for increased seismic activity today and tomorrow, possibly higher 6 to 7 magnitude.

There's more critical geometry ahead on the 9th and 10th which means a high probability of large seismic activity until the 14th, possibly reaching mid 7 magnitude.

Atmospheric signals so far seem to indicate (South) Atlantic, South-America and possibly Central America/Caribbean. Other regions are NOT excluded. This is an indication and it may be wrong.

This could be a time for a strong to major earthquake at the Azores Cape St. Vincent Ridge off the coast of Portugal/Gibraltar, which is a subduction zone. Last megathrust earthquake there was in 1755 (Mw 8.7-9.0) and the last major earthquake (Mw 7.9) was in 1975. The fault may be well overdue.

Strong atmospheric signal in 5 mV band is often a sign of upcoming large seismic activity. Be on watch in the coming days.

Potential for increased seismic activity in Iran and to a lesser degree Turkey, Greece, Romania and the Balkan region.

Strongest signal still pointing to (South) Atlantic, South-America, Central America, Caribbean. See earlier post: https://t.me/ssgeosurvey/561

As expected, increased seismic activity in the South Atlantic, but not yet the anticipated larger seismic activity. Pressure at the South Sandwich Islands Region may be critical.

Next two alignments. Large seismic activity is expected. Be on watch if you are in an earthquake prone area. See also the forecast on ssgeos.org

Seven out of eight planets are grouped in a relatively small region of space. This is why we currently have so many planetary alignments. You can already see an upcoming rare alignment of outer planets (Mars-Jupiter-Neptune), which will happen in about five months.

The absence of even moderate earthquakes is worrying. Since 4 August only three M 5.4+ earthquakes occurred peaking M 5.9 on the 6th. No M6+ earthquake since 3 August. Hopefully seismic pressure in the coming days (10-14) will be released more evenly with smaller earthquakes, but there is a high probablility of one or two M7+ earthquakes.

There is already a high probablility of large seismic activity today (10 August), but certainly 11-13 August. Again, BE ON WATCH!

As the two planetary alignments occurred this morning, the Moon also lined up with Mars. This usually triggers at least a M6 earthquake. However, the largest earthquakes on record also occurred just after the Moon lined up with Mars.

Additional larger seismic activity is possible in the next few days. Be on watch! Forecast: ditrianum.org

We use two devices to measure atmospheric electricity. The difference between them is noise reduction. You can follow the measurements realtime on https://ssgeos.org/atmosphere.htm (updates every 10 minutes).
