Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Large Plume of Volcanic Ash Forces Closure of Heathrow and Gatwick Airports, Britain’s busiest

Volcanic ash cloud is now drifting further south, threatening more chaos in the UK and European flights paths.

A no-fly zone has been imposed for at least a six-hour period between 01:00 BST and 07:00 BST (24:00 to 6:00UTC) by the UK Civil Aviation Authority shutting down Heathrow, Gatwick and London City airports.

The eruption plume is reaching a maximum height of  about 9 km (30,000 ft), about 15 percent higher than yesterday.  The ash cloud is currently drifting in a southeast to east-southeasterly direction, Icelandic Met Office (IMO) said.

Ash fall was detected southeast of Eyjafjallajökull.

Earthquakes

At least 3 earthquakes measuring 5.1 to 5.4Mw have occurred in the Norwegian Sea about 590km to the northeast of Jan Mayen volcano which sits on the Mid-Atlantic Ridge, the divergent tectonic plate boundary located along the floor of the Atlantic Ocean , which also runs through Iceland.

The section of the ridge that includes  Iceland is called Reykjanes Ridge.

Fire-Earth is currently working on an update for its earlier statistical forecast of volcanic eruptions in and around Iceland.
