SUMMARY

The M 8.8 earthquake off the East Coast of Kamchatka on July 29, 2025, triggered several significant aftershocks, including magnitudes of 6.9 and 6.3. The quake, one of the strongest since 2010, resulted in tsunami warnings in Hawaii, with maximum wave heights reaching approximately 4 feet (1.2 m) and minor flooding reported. The earthquake's depth of 20.7 km contributed to a reduced tsunami wave amplitude, and it is confirmed that it will not affect the Southern Oscillation or Pacific currents significantly. Additionally, the Klyuchevskoy volcano began erupting following the earthquake, indicating a potential link between seismic activity and volcanic eruptions in the region.

PREREQUISITES
  • Understanding of seismic activity and earthquake magnitudes
  • Knowledge of tsunami formation and characteristics
  • Familiarity with volcanic activity and its relationship to earthquakes
  • Basic concepts of the Southern Oscillation and its climatic effects
NEXT STEPS
  • Research the impact of deep earthquakes on tsunami generation
  • Study the relationship between seismic events and volcanic eruptions
  • Explore the effects of earthquakes on ocean currents and climate patterns
  • Investigate historical data on earthquakes and their aftermath in the Pacific region
USEFUL FOR

Seismologists, volcanologists, climate scientists, and emergency management professionals will benefit from this discussion, particularly those focused on understanding the implications of seismic events on geological and climatic systems.

TL;DR
A series of big earthquakes occurred near Kamchatka
The entire Northern Pacific seems to be quite active. Kamchatka notes an M 8.8 and several severe quakes afterward (M 6.8) and several above M 5. There have also been earthquakes near the Kuril Islands, which aren't that far away.

There were tsunami warnings in Hawaii. The maximum height was about 4 feet (1.2 m) with some flooding in parking lots and low lying areas along the north or NW coasts.

It was one of the strongest earthquakes since 2010.

Wondering if and how it would affect the Pacific currents and La Nina/El Nino. Or was this earthquake too far away to have any appreciable effect?

This was a deep earthquake, so there will be less tsunami wave amplitude than a shallow quake. It should have no effect on the Southern Oscillation. Storm swells in the Pacific are significantly larger and more energetic than the tsunami generated. The thermal energy involved in the SO will be unaffected by the momentary tsunami.

Thank you.
 
The Klyuchevskoy volcano on Russia's Kamchatka peninsula began erupting on Wednesday following a powerful earthquake off Russia's far eastern coast.

Lava began flowing from what is the largest active volcano in the northern hemisphere. The Russian Academy of Sciences' United Geophysical Service said in a post on Telegram: "A descent of burning hot lava is observed on the western slope. Powerful glow above the volcano, explosions."

Interesting coincidence.
