Quake Watch 2012

Is the current eq activity in the central mid Atlantic range common to happen in a row like they have in the last day?

West of Ahar, Azarbaijan Sharghi Province, Iran, 2 x 6.1mb
there is an error in the data (but its not fatal)

one of my readers pointed out that the aftershocks were not in chronological order.
I couldn't figure it out until I looked back at the Iranian source.
They have Local time then UTC time both listed in seperate columns, but the Date column (which is seperate again) is not adjusted on the conversion to UTC , so because Local time is 4.5 hours ahead of UTC the last 4.5 hours of Local time for the day falls into the next Day UTC.
The Iranians haven't done this.

I've gone back and fixed it, and also reset the events in descending order from the first Main shock.
and
a *NEW* feature, on each pop up tag the elapsed time since the main shock is given





Last remaining question though;
Iran has 2 x 6.1 quakes

GCMT has 6.5 and 6.3
USGS has 6.2 and 6.3

so which one is the Main shock?

I've teamed up with earthquakereeportdotcom
still negotiating over icon color/magnitude, they want different colours than what I have been using for 3 years

SINGAPORE, Aug 18 (Reuters) - A magnitude 6.6 earthquake struck 35 miles southeast of Palu on the Indonesian island of Sulawesi on Saturday, the United States Geological Survey said.

The quake was originally reported by the USGS as a magnitude of 6.5. The depth was reported at 12.5 miles.

The U.S. Pacific Tsunami Warning Center said a destructive tsunami was not generated by the earthquake and that the Japan Meteorological Agency may issue additional information on the quake.

JAKARTA, Indonesia — A strong earthquake of 6.6 has rocked a north Indonesian island. No tsunami warning has been issued and there are no immediate reports of damages or casualties.

The U.S. Geological Survey says Saturday's quake struck 56 kilometers (35 miles) south-east of Palu city on Sulawesi Island at a depth of 20.2 kilometers (12.6 miles). It hit at 17:41 local time (0941 GMT).

Indonesia is prone to earthquakes because it is in the Pacific Ring of Fire, an arc of volcanos and fault lines encircling the Pacific Basin.

6.6-magnitude quake hits Indonesia's Sulawesi: USGS - Agence France-Presse

PALU, Indonesia - A 6.6-magnitude earthquake hit Indonesia's central Sulawesi province on Saturday, the US Geological Survey said, sending terrified residents fleeing into the streets.

The quake struck on land 56 kilometres (35 miles) southeast of the city of Palu at around 5:40 pm (0940 GMT) at a depth of 20 kilometres (12 miles).

Panicked residents in Palu ran from their homes as the ground shook violently for a few seconds, an AFP reporter said.

"We've received no reports of damage or casualties... We'll continue monitoring," Indonesia's Meteorology, Climatology and Geophysics Agency technical chief Suharjono, who like many Indonesians goes by one name, told AFP.

The Indonesian agency earlier reported the quake's magnitude at 6.2 at a depth of 10 kilometres (six miles), with its epicentre in the populated mountainous district of Parigi Moutong.

Indonesia sits on the Pacific "Ring of Fire" where continental plates collide, causing frequent seismic and volcanic activity.

A number of houses in Sigi district and Parigi Mauntong district were damaged after a 6.2- magnitude shallow quake jolted Central Sulawesi of Indonesia on Saturday, local official said.

"The reports I got say that many houses in Sigi district and Parigi Mountong district have been damaged, but we still do not know the exact figure yet," Holi Setiawan, head of the Emergency Unit of the Disaster Management and Mitigation Agency in Central Sulawesi told Xinhua over phone from there.

Identification of the impact of the quake was underway, he said.

The quake struck at 16:41 p.m. Jakarta time (0941 GMT) with the epicenter at 27 km southwest Parigi Mountong of Central Sulawesi and with the depth at 10 km under land, an official of the Meteorology and Geophysics Agency told Xinhua.

The intensity of the quake was felt at 3 to 4 MMI (Modified Mercalli Intensity) in Palu town of Central Sulawesi, the official said.

The USGS said the quake was 6.6-magnitude. Indonesia is vulnerable on earthquake as it sits on quake-hit zone, the so called "the Pacific Ring of Fire."

JAKARTA (Reuters) - A magnitude 6.6 earthquake struck 35 miles southeast of Palu on the Indonesian island of Sulawesi on Saturday rattling crockery as people were breaking the Ramadan fast but there were no immediate reports of casualties or damage, authorities said.

The quake has no tsunami potential and no damage is reported, said Subagiyo, an earthquake center official in the capital Jakarta.

The U.S. Pacific Tsunami Warning Center said a destructive tsunami was not generated by the earthquake and that the Japan Meteorological Agency may issue additional information on the quake.

A powerful 6.3-magnitude quake shook Indonesia's central Sulawesi province on Saturday, the US Geological Survey said, sending terrified residents fleeing into the streets.

The quake struck on land 56 kilometres (35 miles) southeast of the city of Palu at around 5:40 pm (0940 GMT) at a depth of 20 kilometres.

Residents near the epicentre in central Sulawesi districts of Parigi Moutong and Sigi reported around 15 seconds of violent shaking, with panicked residents running from their homes.

Herlina, a receptionist at the Tunas Harapan Hotel in the town of Parigi, told AFP the shaking sent guests running into the street.

"Everyone was scared... but everything's fine now. There was no damage to the hotel and I haven't seen any damage on the street," said Herlina, who like many Indonesians goes by one name.

The tremor was also felt in the provincial capital Palu, an AFP reporter said.

"We are sending a team into the (interiors) to see if there is any damage or casualties there," said Ramli Borman, head of the Parigi Moutong Disaster Mitigation Agency.

USGS initially reported the quake's magnitude at 6.6, while Indonesia's Meteorology, Climatology and Geophysics Agency measured it at 6.2.

Magnitude-6.3 quake hits northern Indonesian island; no tsunami warning, at least 2 injured

* Article by: Associated Press
* Updated: August 18, 2012 - 8:13 AM

www.startribune.com/world/166634476.html

JAKARTA, Indonesia - An earthquake registering magnitude 6.3 rocked a northern Indonesian island on Saturday as residents were ending their fast on the final day of the Muslim holy month of Ramadan, officials said. There were reports of at least two injuries but no tsunami warning was issued.

The U.S. Geological Survey said the late-afternoon quake struck 56 kilometers (35 miles) southeast of Palu city on Sulawesi Island at a depth of 19.9 kilometers (12.4 miles).

Sudirman, an officer at the Disaster Management Agency who uses one name, said there were reports from the province that at least two people were injured by falling debris and of damage to houses in Parigi Mountong, the district closest to the epicenter.

He said the full extent of the injuries and damage was not yet known.

The earthquake struck as people in the province were ending their fast on the last day of Ramadan, causing many to rush out into the streets in panic, local news reports said.

The USGS initially measured the quake at magnitude 6.6 but later adjusted it to 6.3.

Indonesia is prone to earthquakes because it is in the Pacific Ring of Fire, an arc of volcanos and fault lines encircling the Pacific Basin.

A giant quake off the country on Dec. 26, 2004, triggered a tsunami in the Indian Ocean that killed 230,000 people, half of them in Indonesia's westernmost province of Aceh.

whats wrong with the dates?
I haven't got time to cross reference USGS with IISSE (the Iranian earthquake network) but those items look OK, USGS seem to have overestimated some of the quakes sizes.starting at the bottom of that list the 4.9 is the one between the two 6's , the 6.3 is the 2nd 6.
Iran is not one of those places where USGS (or the US for that matter) has people on the ground , so take the data with a grain of salt. (ie ignore it)

How is it that when I put a post on ATS it immediately shows "posted 5 minutes ago"?
no wonder the 4 hours for editing a post runs out prematurely at 2 hours
