66.6 mV? That is the lowest I have ever seen.

That must be picking up everything including cows farting.

This a bit rare that are more Frequent earthquakes dont you agree?

What really gets me is the earth quacks! Absolutely deafening at times. I really wish the earth would not 'quack' when I am trying to concentrate.

Sorry! Could not resist that!

Aside from that I would not have said the frequency was anymore than usual and let's face it earthquakes can occur anywhere (although they are generally around tectonicaly or volcanically active zones)

Yes, a few - one of which (Gaua I believe) is currently causing concern and preparations have been made in recent months for an evacuation if needed.

4.0 was just downgraded to a 3.4, but it does keep rumbling there.

Been busy yesterday afternoon and overnight in NZ.

Events of interest were;
*That 475km deep quake off North Cape, 4.562ML, you don't often see quakes that far back west of the Collville Ridge or that far north of NZ ( until you get up to the South Fiji Basin area)
*Another aftershock at the Takaputahi River, thats a lot of aftershocks for a measly 4.5ML mainshock (15th-19th May, 3 threes and 4 twos)
*Whale Island went off again for a couple of hours 2:38am-4:36am NZST this morning, as well as the 3's on the list below there were 11 additonal events 2.175 to 2.834ML), that 4.32 on the list is the biggest quake in the swarm so far and was a bit further out to the NW, 6km from Whale Island.

From the USGS

Today’s Earthquake Fact
The May 19, 1940 earthquake in southern California, magnitude 7.1, caused a horizontal land movement that displaced the international boundary, between the United States and Mexico, a few feet.


- Now, I ask, why one would aggrivate this area with a geothermal power plant?

Ive literally just posted this to another thread................
You want to sound troubled too, because i was thinking last night that theres a massive problem. And im not talking about damaged due to oil. Im talking about the massive earthquake which i think may have a possiblity due to the sea water replacing the oil in the reservoir which is leaking. Because if im talking sense then the oil that has leaked was replaced by sea water. What negative effects will happen if this is right? Earthquake? Land sinking into the ground?
I may be wrong, who knows? Anyone?


Could i be right?

There have been another 8 quakes in the Whale Island Swarm since I last posted, 2.759-3.699ML, many of them felt in the area.
www.geonet.org.nz...

I haven't got time to go behind the scenes and dig out the details right now ......... off to the Chiropractor.

We've had a swarm of earthquakes here in Whakatane, New Zealand last night and this morning. Brings back bad memories of the Edgecumbe earthquake in 1987.

Hope our live volcano doesn't decide to erupt, White Island, otherwise it's curtains for us in the Bay of Plenty.

Hey tina how far are you from Whale Island?

I wouldn't worry too much about White Island, there were way more quakes in the 2 Matata Swarms in 2005 and 2007 and they never affected WI at all.

There were a couple more felt 3+'s this arvo.

Sleepless in Whakatane

People in Whakatane will have had a sleepless night as 7 earthquakes over magnitude 3 occurred about 10 km north of the town. The largest of them was magnitude 4.3. Map showing the cluster of earthquakes located north of Whakatane. Map showing the cluster of earthquakes located north of Whakatane. Earthquake swarms are not uncommon in the Bay of Plenty. The town of Matata has experienced several episodes of earthquake activity in recent years. Whakatane lies close to large scale fault structures on the eastern boundary of the Rangitaiki Plains (between Matata and Whakatane). This area is what geologists call a graben. Basically the two masses of land are very gradually pulling apart, although at an extremely slow rate, about 1 cm per year. Faults in the earth's crust have arisen from this east-west spreading across the region. It is movement within these faults that is causing the earthquakes. We can't predict what will happen with swarms.

They may carry on for hours or even days, or the centre of the earthquakes might move around. In the meantime we will be locating the bigger shakes, and please keep the felt reports coming in!

I have been having visuals of that one..... Mabey that would cause the tsunamis a lot have dreamed about and predicted etc..

SAN JOSE (BNO NEWS) — A strong earthquake struck off the Pacific coast of Costa Rica on Thursday afternoon, shaking buildings in the capital of San Jose. The 6.2-magnitude earthquake at 4.16 p.m. local time (2216 GMT) was centered about 42 miles (67 kilometers) south-southwest of San Jose, or 91 miles (147 kilometers) west-southwest of Limon. It struck about 24.1 miles (38.8 kilometers) deep, making it a shallow earthquake, according to the U.S. Geological Survey.
There were no immediate reports of damage or casualties, but residents in San Jose reported feeling light shaking. The earthquake was not powerful enough to pose a tsunami threat.

Also, at the top of that page, there is a report that it was upgraded to a 6.3.. not much of a difference, but thought I would add that.

Edit to add:

SAN JOSE (BNO NEWS) — Tsunami warning center upgrades magnitude of Costa Rica earthquake to 6.3.

6.3 what?

Geofon has 5.9mb but it hasn't been manually revised yet.

I calculate from the Geofon phase data using 9 stations that gave ML that it was a 6.566ML (Local Magnitude) (Richter)


edit: I see USGS have downgraded it to 5.9 (GS) and list it on the other scales a s 5.6mb ( Body Wave magnitude) and 5.5MS (Surface Wave magnitude)


Whenever the magnitude type in one of our lists is given as 'M', this means, that the seismological observatory reporting the specific magnitude did not specify, how the magnitude was computed. Often, these are magnitude values from the NEIC. You may assume, that such a magnitude value represents 'their best effort', and for strong earthquakes such magnitudes often are magnitudes of the type Mw.

I'm starting to wonder if (GS) that USGS is using doesn't mean GueStimate

I think that the 6.3 update was from Costa Rica itself. It's funny that it took the USGS so long to downgrade it considering it was checked by a seismologist and still reported for well over an hour as a 6.2.

Anyway, I was glad to see that there was no damage or injury. That always gets a from me.
