(Major) Earthquakes list January 7, 2013

Moderate shallow earthquake in Chiapas, Mexico

the hypocenter (focal depth) was very shallow (1 to 10 km) depending on the reporting agency.

ER does not expect serious damage or injuries based on earlier earthquakes in Chiapas

44 km N Matías romero (pop 21,064 ; local time 12:24:41.2 2013-01-06)
22 km NE Palomares (pop 4,465 ; local time 12:24:41.2 2013-01-06)

Update 18:45 UTC : Close to Providencia. The area is a wilderness and farming area with almost no important city.

Update 18:47 UTC : The epicenter is following the USGS at a distance of 7 km from Palomares. A difference of 15 km in between EMSC and USGS, not uncommon in seismology.

The earthquake was felt in a radius of several hundreds km.

Alaska earthquake yesterday and aftershocks today

Nothing special is happening. Just normal aftershocks in the 4 to 5 range. We have noticed that a tweet from yesterday’s tsunami was send at 10:14 UTC on Sunday. It came just before an aftershock of 4.5. Alaska tsunami center is sending tsunami messages for moderate quakes. Unless our system is in error (should be an exception then) it means that we have received a message in our stream. Sorry about that, but that is the disadvantage of automatic systems. Once again : nothing unusual is going on, which you will see when you click on the link. The message on Sunday comes from the Pacific Tsunami and Weather Center (PWTC) and not from the Alaska Tsunami center.

January 6, 2013 volcano activity

KVERT reports continued lava effusion from the southern fissure at Plosky Tolbachik (Kamchatka Peninsula) today.  Volcanic tremor accompanying the eruption remains at slightly higher levels than during the previous week.

Earthquake information for Long Valley Caldera (CA) is not updating(?), so no current information on the (probably) on-going deep earthquake activity beneath Mammoth Mountain volcano (CA).

Exhalations have diminished in frequency again at Popocatepetl volcano (Mexico).  Emissions of gas and some ash now occurr at an average rate of less than two events per hour.

Great volcanocam shots of two Guatemalan volcanoes (Fuego and Santa Maria) in action today. 

At Fuego, blocks spall from the snout of an active lava flow to produce rockfalls with accompanying dust clouds, while at the Santiaguito Dome Complex (Santa Maria), explosions generate ash clouds that mushroom above the edifice.

Seismograms from Santa Maria (STG6) show periods of increased volcanic tremor which can be associated with the explosive activity, while seimograms from Fuego (station FG3) are non-descript, showing only low-level volcanic tremor. 

Meanwhile, nearby Pacaya volcano (station PCG) remains on-the-perk with numerous small volcanic earthquakes and periods of low-level volcanic tremor.

A swarm of volcanic earthquakes is underway (until receat San Miguel volcano (El Salvador) (station VSM) today.

Seismicity at San Cristobal volcano (Nicaragua) (station CRIN) continues a slow, steady diminuition, while volcanic tremor at nearby Masaya volcano (station MASN) has notably risen during the past week.

Small volcanic earthquakes and periods of low-level volcanic tremor affect Nevado Del Ruiz volcano (Colombia) again today (station OLLZ).

Seismicity at Tungurahua volcano (Ecuador) (station RETU) is at the lowest level since eruptive activity re-commenced at the volcano in late December 2012. 

No recent updates from EPN on the inflation state of the volcano. Seismicity at Reventador volcano has also declined in the past 24 hours (station CONE).

A significant SO2-enriched plume still wafts from Copahue volcano (Chile).  This and periodic earthquake swarms suggest the volcano has some unfinished business.

Strong (wind enhanced?) tremor today at White Island volcano.  Tremor-like signals also occur on seismograms (see spikes in tremor levels on spectrograms) recorded at the other New Zealand volcanoes, Tongariro and Ruapehu.  There is some suggestion of wind shear in the fume cloud hovering over White Island, and the simultaneity of tremor spikes at all three volcanoes suggests a wind event, but look at the flags in the Ruapehu photo.  Fume hovering over Tongariro also does not seem to be disturbed by significant wind.  Oh well, no news is good news from Geonet.
