Morning Bushcraft Bear report. Schools closed again.

edit: new Geology Hub on la Palma talking about why the geologists got it so wrong.

I wish the wind would pick back up. When there's no breeze the ash falls on the towns, causing trouble for people and (most importantly) making it hard for us to see what's going on.
 
High activity of earthquakes this morning on La Palma, the strongest of magnitude 4.8 (7:27.36) and 5.0 (7:27.39). They have occurred only three seconds apart, which is why it has been noticed as a long-term tremor. Both located in Villa de Mazo, with a depth of 35 and 36 km. (Source)

The air quality was really bad last night, the Emergency Services and the Government of La Palma issued a warning to the population:

5.1M Earthquake

The revised measurement of the IGN has confirmed that it’s a 5.0.

It's logarithmic, right? A 5 is 10 times a 4?

Yes, but the other way around. A "5" on the scale is ten times the amplitude of a "4"
Edit: I am retarded and read your post wrong, but yes, you're correct. I went and checked the log base as well. Half expected it to be a natural log, but it's base 10.
Edit edit: Word filters are back? Neat!

So many earthquakes, lots of ash, some blue smoke... I kinda think the volcano is preparing to do something interesting.

Hmm.. Greece got a 4.3 earthquake a little while ago. Seems like when that area starts shaking, La Palma chills for a bit.

Interesting 20 minute long earthquake

Wtf was that?

20 minute long full quake? or 20 minutes quake and aftershocks. Because even hitting 5 minutes of sustained quake is "massive fault line displacement" levels. Whereas being followed by aftershocks for a long time is exceedingly common, just only usually noticed when the first quake was massive enough that its aftershocks are still well felt.
 
Seeing it break 5.0, yeah if anyones on the west side of the island nows probably the last best chance to bail the fuck out - I know I'm sounding like a broken record, but St. Helens went off at a 5.1, and these quakes are getting far too shallow, not to mention frequent. While I'm not expecting the fault to go, the island to pull an Atlantis, and a giant fuck off tsunami, I still feel like we're at the point anyone left on the island needs to take Shorty's advice...

 
I haven't seen a single measurement from a vulcanologist on the surface fault having moved a peep. But then again I haven't see a single measurement at all on the surface fault (if it is indeed a genuine fault of concern).

But the data says this of the 5.0 "Magnitude recalculated from 4.8 to 5.0. Hypocenter depth recalculated from 36.0 to 35.0 km (from 22 to 22 mi)."

That is not shallow. 3-5km depth is the target zone for concern.

That actually makes some sense when you pull up the fault lines. I
