M 8.8 Off East Coast of Kamchatka

AI Thread Summary
The Northern Pacific region is experiencing significant seismic activity, highlighted by a magnitude 8.8 earthquake near Kamchatka, Russia, followed by several aftershocks, including magnitudes 6.9 and 6.3. This earthquake, one of the strongest since 2010, triggered tsunami warnings in Hawaii, with maximum wave heights reaching approximately 4 feet and causing minor flooding in coastal areas. The earthquake's depth suggests a reduced tsunami wave amplitude compared to shallower quakes, and it is unlikely to impact Pacific currents or the Southern Oscillation significantly. Additionally, the Klyuchevskoy volcano on the Kamchatka Peninsula has begun erupting, with lava flows and explosive activity reported following the earthquake.

TL;DR Summary
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.
