TIDAL EFFECTS ON SEISMICITY
March 27, 2023 is the sixth day after the beginning of the lunar month. Regions most likely to experience tidal triggering on this day (With associated magnitude ranges; the percent change in seismicity rate over background seismicity rate on this day of the lunar month; statistical z-value and significance level) are:
Region Magnitude range %change z-value Significance level
Indian Ocean MB>=4.0 17 2.1 0.05
Kamchatka MB>=4.0 35 2.6 0.03
Regions expected to experience reverse triggering (i.e. they are unlikely to experience a significant event at this period of the lunar cycle) are:
Region Magnitude range %change z-value Significance level
Global MB>=6.0 -17 -2.8 0.02
West Pacific MB>=4.0 -20 -1.9 0.05
Yellowstone MB>=0.0 -19 -2.0 0.05
Puerto Rico MB>=4.0 -17 -1.9 0.05
WEATHER PHENOMENA
Some seismicity may be affected by weather due to wind, tidal surge and air pressure systems effects of the continental mass compared with adjoining plate masses. During the tropical storm season in the Northern Hemisphere we keep an eye on tropical storms which may affect seismicity according to our models. Currently the following tropical storms appear to have potential to affect seismicity in the coming week:
No tropical cyclones are currently active.
