Four minutes ago, here in Portugal (or at least I felt it here in Portugal).

The way things shook I think it was something like 5.5 or 6.

Tomorrow I should have more detailed information. I hope.

That was most likely what you felt

Yes, it was that one.

It was the strongest earthquake in continental Portugal (there have been stronger ones in the Azores) in the last 40 years, and up to now there were 20 aftershocks.

Wow, was there any damage reported over there? Is it getting much coverage?

No damages reported, but all people that I know noticed it, even those that were sleeping at the time, they were awakened by the earthquake.

A 5.4 in the Azores Islands reigons

USGS 5.4 Azores Quake

A 5.4 just reported in Southern Alaska

Location:59.248°N, 153.613°W
Depth:89.3 km (55.5 miles)
Reigon:SOUTHERN ALASKA

Distances: 61 km (38 miles) ESE (121°) from Pope-Vannoy Landing, AK

68 km (42 miles) ESE (108°) from Kokhanok, AK
303 km (188 miles) SW (226°) from Anchorage, AK

^ could this be the beginning of something bigger perhaps? Quite a few between 5-6 lately. Anyone a little more in the know care to weigh in on any of these?

6.4 Mag in Taiwan

One thing I noticed in those USGS links is that the information about Portuguese earthquakes, the values do not match the ones from the Portuguese authorities.

In the case of the one I felt, for example, the USGS site says:

Magnitude: 5.5
Depth:10 km

While the Portuguese "version" says:

Magnitude: 6.0
Depth:31 km

For the Azores (or Açores, as we call them ) eathquake:

USGS

Magnitude: 5.4
Depth:10 km

Portuguese Meteorologic Institute

Magnitude: 4.9
Depth:5 km

Looks like Malawi and Tanzania have been suffering quite a spate of strong quakes running from around 9th Dec up to the "Magnitude 6.0 * Saturday, December 19, 2009 at 23:19:18 UTC * Sunday, December 20, 2009 at 01:19:18 AM at epicenter " (USGS). I noticed that of possible interest is that "The district is home to the uranium mine opened in April by Australian company Paladin." news.com.au article link and they are near a large inland body of water.

g'day all...
first time post for me so go easy
I apologise if this has already been posted.

I was speaking with my japanese girlfriend (who lives in Shizuoka Japan) via skype and the news was on the background.
As the news was read, she looked a little surprised and I asked what had happened.
She explained that in the IZU peninsula, the place had received in excess of 200 quakes/tremors (i think she said per day).
link to show location of Izu: www.japan-guide.com...

Now if you know of Japan, you will know that Japan has a number of earthquakes every day however, even they are reporting this as unusual.

So having read a few posts on this site with people always asking for proof, i went to the Japan meteorological agency's website and had a look for myself.
www.jma.go.jp...
if you click on the 'previous information' button you can see according to the time stamps the amount of earthquakes in the area.

The news caster (according to the MRS) said that scientists were worried this is a sign of the plates preparing to do a shift which they believe is a prelude to the 'Tokai' earthquake.

The Tokai earthquake is long overdue and like Americans waiting for the supposed 'big one' to come, this is Japan's 'big one'.

According to the meteorological website linked above, they even have a prediction page for the Tokai earthquake however it would suggest (given their is no warning data) that either my girlfriend or the news caster may have slightly exaggerated things.

In any case, i will be there for xmas & new year and i hope it doesn't come.

On a side note, the first ever earthquake i experienced was when i was living in japan. I was lying on the couch watching the telly and the next thing i knew i'd been thrown off the couch and was lying on the floor.

Living in japan i was told some interesting things regarding earthquakes.
(i don't know how true and i never researched)
- I was told there were 2 types, lateral movement & horizontal movement. The worst type being horizontal.
- They (& the chinese) believe you are forewarned of an earthquake with particular cloud shapes (jishin kumo).
www.earthquakesignals.com...

I did witness one of these clouds similar to the one in the link. My girlfriend took a picture of it on her camera phone way back in 2001 but we don't have it anymore.
It looked like a plane had blown up at a particular point and crashed. It was like an explosion point which trailed across (appeared to fall to the ground) but you could see the end so it never touched the ground.

I didn't believe what they had told me, i continued to think it was a plane crash but there were no reports of it. 6 days later a magnitude 6 earthquake hit 100k north of tokyo. We were about 200k south of tokyo in a place called hamamatsu.
Do i believe? maybe, i dunno but it makes sense to think that for any type of occurence there are certain forewarning factors.

If I am not mistaken, the Romans also had that idea of "earthquake clouds", but I don't know how reliable that may be.

reply to post by Necrosis


BBC has an article on this quake today. They say it was a double-quake and that it was a record quake as well. A very unusual quake...


BBC: Earthquake ‘double whammy’ caused 2009 Tonga tsunami

18 August 2010


In a rare set of events, an initial 8.1 magnitude earthquake was immediately followed by a second 8.0 shock.

An estimated 192 people died as four waves each more than five metres high surged inland.

the initial Tonga earthquake occurred up to 100 km (62 miles) from the closest tectonic plate boundary. As such it is the largest ever earthquake of this type reported in more than 100 years of monitoring.

Professor Lay commented that the Tonga earthquake was "unlike anything seismologists have seen before".

unfortunately I couldn't get the kmz file to load to Google Maps to be able to have an interactive map of all the 17,000 icons, the file is just too big, says 782 KB (801,071 bytes) on my folder, but when I was loading it to Google Earth I had to split it into 2 parts then combine them, each part was about 7MB at that stage.
The best I can do is provide the file and people can download it themselves on GE.

depending on your browser settings you may have to right click the link and "save link as ...." to your Downloads folder and then open it from there.

I took this awesome screenshot at 5km above the ground, you can almost see the ground shaking
