Here's What Scientists Know About the Tonga Volcano Eruption

While residents of Tonga struggle to recover from a devastating volcanic explosion that smothered the Pacific island nation with ash and swamped it with water, scientists are trying to better understand the global effects of the eruption.

They already know the answer to one crucial question: Although it appeared to be the largest eruption in the world in three decades, the explosion of the Hunga volcano on Saturday will very likely not have a temporary cooling effect on the global climate, as some past enormous eruptions have.

But in the aftermath of the event, there may be short-term effects on weather in parts of the world and possibly minor disruptions in radio transmissions, including those used by global positioning systems.

The shock wave produced by the explosion, as well as the unusual nature of the tsunamis it generated, will have scientists studying the event for years. Tsunamis were detected not just in the Pacific, but in the Atlantic, Caribbean and Mediterranean as well

1. I don't understand why there aren't earthquakes all over the place?

VAST masses of water have been putting unusual pressure on all sorts of tectonic plates and collision zones. The whole planet vibrated just like after Fukushima.
Some sort of sympathetic reaction must be happening, but I haven't heard of anything serious.
