USGS
EMSC

USGS is reporting a Mag 6.6 mwp only 9.3 km under Taiwan.
Geofon have it Mag 6.3, same depth.
EMSC say it was Mag 6.7 mi at only 5 km deep.

That is a large population exposed, whatever the final numbers are determined to be.


USGS Pager lists as many 350,000 people exposed to strong shaking.

Earthquake-Report has some good testimonials linked:

New Taipei City - The japanese style doors in my house made a HUGE ruckus and my dog was so scared, he pooped himself.
Taichung - Felt like (and sounded like) 100 giant trucks driving by and shaking up the building,
Hangzhou City - Swaying of apartment building, felt dizzy

EMSC has changed it as 6.3M at 5km deep. Here are some testimonies:

Witness location : Wuqi District (Taiwan) (113 km NW from epicenter)
I stay in Taichung,but I received calls from friends up North in Taipei how felt the earthquake , people were leaving the restaurants and buildings into the streets

Witness location : Dong District (Taiwan) (136 km NW from epicenter)
The slight swaying lasted close to 2 minutes

Witness location : Banqiao District (Taiwan) (153 km N from epicenter)
It was my first experience of an earthquake.

Witness location : Zhongshan District (Taiwan) (171 km N from epicenter)
It set of a couple of car alarms in the street

There was no damage seen, and no injuries. But the area is very mountainous and remote, so it could take time before we know for sure.

If you mean all the coloured balls kdog they are produced in the IRIS Earthquake Browser

You will see a download of a free URL builder for it in my signature, and I am adding it to the QVSData program as we speak so in a list you just right click and send the epicentre to the tool.

Hold on downloading for a few hours however as I am about to add selection of the map background.

The straight web version is here

Oh Dear. Those precious people.

They are used to quakes but that one has to hurt.

There's a section of train track along the East coast above Hualien that is constantly moving. They have to redo it every so many weeks/months or so, IIRC.

Prayers for the people.

Beautiful area.

change the date to see 31/10 data

I don't know how long they have had the monthly lists, never used to be there, I feel a new page coming on eqarchives

Very interesting, I've never really read much about that side of things, you really are a Gem

is that where you got your name from?
en.wikipedia.org...

Mg-rich olivine is stable to pressures equivalent to a depth of about 410 km within Earth. Because it is thought to be the most abundant mineral in Earth’s mantle at shallower depths, the properties of olivine have a dominant influence upon the rheology of that part of Earth and hence upon the solid flow that drives plate tectonics

so is that the answer, to the question "what causes earthquakes?"

apropos the post by PuterMan aka PM


OK Folks, the latest version of the IRIS Earthquake Browser URL doodad is available. Downloads from this page (or my signature)

This version adds the abiity to select the map type, and the map captions now work. I have also done some more work on the lat/lon parsing.

Hybrid. Basically the satellite view with roads and stuff
Satellite. No roads or names. Just plain old Mother Earth
Terrain*. Good close up view as a map with contour lines etc
Road Map. Plain old map with roads surprisingly - not that the others don't

*Defintely my prefered mode.

Lol, you're clever, I see what you did there. Peridot is my alter ego.

Yes, that is where my moniker comes from. I used to be a bit of a rockhound when I lived in the far northwestern corner of California. Besides the small amounts of gold, platinum, iridium and jade that were my prized finds, I once found a tiny smattering of beautiful olivine micro crystals in a pocket of unweathered peridotite.

As far as olivine phase changes being the cause of deep earthquakes...maybe...probably? I leave that to the scientists.

Anyone else here ever made the mistake of putting a stone from the river in a campfire?
They explode when the water inside turns to steam.

Rocks have pores, and those pores can hold a lot of water (as well as other liquids and gases).

I think that good old liquid water is probably the most overlooked "variable" in seismic modeling.

Thanks,man, I will go check it out!

Is it just me, or does southern California look like it has the shakes?

I thought that as well, it was noticeable enough for me to get on and see what the xperts are a-sayin...
I always like to check out the past 7 days activity to see if it's just a 'day thing' or if it's a 'trendy thing'.

I vote for trendy...

Taiwan 2013
click, click, click x 10 times, done
lots of energy released there (Taiwan), 563,850.118TTNT so far this year, no M7's though.
In fact all those quakes add up to equal one single M7.05

reply to post by sageturkey


It seems like a growing trend to me too.

I've read a few different papers showing that an increase in micro-quakes in the crust near the epicenter of an impending big quake, can begin months or even years before the large quake strikes.

It will be seen as a small, but staticstically significant increase in small quakes, that become more frequent the closer in time we get to the future rupture; but then the microquakes slow to a stop. In some cases just days before the big event, but it can be 4-6 months of quiet. Then snap!

This activity in California has that "feel"; that it has been slowly quickening. I should go back and look at monthly totals over the past few years to see if there really is an increase, and where exactly, or if I'm just paying closer attention than I was 3 years ago.

reply to post by muzzy

You've gotten so fast at whipping up these maps, kudos. I'm still hoping the scaled baubles will win.

What the heck is going on at Chichuachua (Mexico)?
I noticed the last 3 months suddenly there is activity there, nothing prior.

here is Octobers map centred there,
if you look back over the months in 2013 you will see what I mean
whatever it is, it seems to be getting more intense by the month

could be a new seismograph was installed in that area, would explain why there is no data prior, maybe........... but there are lots of M4's, which are usually picked up by seismos in other areas anyway.

I've criticized Holland.
But I like his plan.
Prove with data. And I, nor anyone else, have to argue the causal link.
Although, I can argue, (anything) that it has already been proven.

While I'm here.
Overall, and over the last half turn around the world, things have been relatively quiet. Looking at the numbers, I'm sure it's been average. I think that's because this last decade has had some real nightmares. And it wasn't really the earthquakes that brought the real destruction. It was those two tsunamis. I'm not counting Haiti. Those deaths weren't due to the earthquake. The loss of life was bad building design. There's a one word answer for their lack of preparedness. Poverty.

Trust me I'm not naïve. The real answer is complicated and long term, and yes, money has always poured into Haiti. I'm not talking about population. The long and accurate answer is slavery has cursed the Haitian people. Not voodoo.

It's really windy today. Branches are falling. Apples too. Wind means change.


Oops lost my main point. South America. Way too quiet for way too long. The last few days excluded. These recent ones maybe mean that that giant fault may wake up in a big way.

These recent ones maybe mean that that giant fault may wake up in a big way.

Or maybe not. It was 50 years between the two big ones. The 1960 is not on this but here are the 20 largest as a map and as a list.

USGS is only showing 4 - M4+ events in the last 30 days.

There are a heck of a lot more on your map, although many are at or near the 4.0 boundary.
SSN and USGS have a slight difference in opinion regarding the magnitudes?
