So many particulars. So many questions.
pretty sure there will be no repeat of that nuke powqer plant failure- they'll have locked it down well tight.

Pretty big M8.0 earthquake just off the Solomon Islands in the Pacific. Widespread tsunami risk for the Solomon islands, Vanuatu, Papua New Guinea, Nauru, New Caledonia and Tuvalu thought to be high over the next few hours. Risk to Hawaii under evaluation.
Edit: now revised to M7.7
2e2a: re-evaluated to M7.8 and tsunami warnings for the Solomon islands, Vanuatu and Papua New Guinea only.

Interesting BBC News item on the data products coming out of the European Sentinel radar (SAR) satellites (1A+1B). The UK Centre for Observation and Modelling of Earthquakes, Volcanoes and Tectonics (COMET) are processing interferometric data to produce maps of tectonic strain, arising as the Earth's crust very slowly buckles and stretches. Initially these are of the Alpine-Himalayan seismic belt, but eventually they will be extended to all major seismic areas.
Illustration of the westwards march of the bulk of Turkey relative to surrounding areas of Asia:
COMET have also analysed data relevant to the recent NZ and Italian quakes.
The technique highlights movements of a few millimetres per 100km per year and in doing so will hopefully lead to maps of regions most at risk from quakes, including regions probably previously thought to be fairly stable.

M8.0 just east of Papua New Guinea a few minutes ago.
In other earthquake news - an interesting citizen science smartphone based seismometer app: MyShake
e2a: Tsunami warning 1058UTC: hazardous tsunami waves from this earthquake are possible within the next three hours along some coasts of Papua New Guinea, Solomon Islands, Pohnpei, Chuuk, Indonesia, Nauru, Kosrae and Vanuatu.

One aim is to be able to give people several seconds warning of quakes (P-waves arriving ahead of destructive S-waves and surface waves) to give them extra time to move to a safer location (get out of building and in to the open).

I've downloaded the My shake app.. Didn't take long to turn off notifications.. So many earthquakes :O

New research suggests that Northern Europe gets a good coating of ash from a volcanic eruption on average every 44+/-7 years (based on the last 1000 years of data - derived from soil core samples taken from peat lands and lake beds). The main source of such ash is Icelandic eruptions of VEI>=4 (that's an Eyjafjallajökull or stronger).

Katla volcano (Iceland) - CURRENT ACTIVITY - Increasing number of earthquakes ?
Katla and the associated range have been increasing in activity end of 2016 and continuing now. It has become a bit of a talking point as generally the attitude to earthquakes and eruptions is a bit shrug of shoulders but the massive increase in tourism means that the evacuation plans for the areas likely to be affected are no longer viable.

Mt Agung getting really itchy now. Small phreatic eruptions have been observed for several days but magmatic eruptions began Saturday. An ash cloud, up to 30kft, expanding to the south and east has impacted some aviation (aviation code red) with ash raining down on some areas. All flights from Australia now cancelled (local airport now reported closed). Volcanic activity alert level pegged at the highest notch (four=warning, eruption imminent/on-going). Evacuations out to 10km from the volcano.

Should be worried? How far away around the world are you?

That all rather depends on how close you plan on getting to it in the coming weeks/months.
At the last eruption in 1963 some 2000 locals, within about 10km of the volcano, were killed (lava, ash, pyroclastic flows, lahars) - hence the current extent of the evacuation zone. It produced some interesting sunsets with luminous twilight glows globally for many months afterwards plus contributed to a small (<0.5 degC), temporary, global cooling (due to SO2 emission producing a short lived sulphuric acid haze that curbs solar UV input - eventually the suspended droplets return to Earth, generally being washed out by precipitation). Rolling forward to now obviously there will be some aviation impact but the degree of which will depend on the nature and size of the eruption and atmospheric state prevailing at the time and thereafter.

Mount Agung finally blew.
