Interesting
Interesting that the USGS does not report ANY activity in the area over the last week....
Maybe no sensors in the area???? But, then again they should be able to sense even small earthquakes from seismographs even 100's of miles away.

Yes... but she said it is not even felt in Tortugas... so very localized. However cracking concrete is significant!

The earthqualke maps are very detailed if you live in CA, NV OR and WA -- and in these locales will show quakes of 1 or 2 magnitude. But the maps you
find on the web for Mexico rarely show any quakes under 3 magnitude. So. if you have a landslide or low-level volcanic activity shaking things in
Ascunsion, you probbably won't see it on the web maps of quakes.
BTW, the majority of Baja has tranform and extensional structures, and it is not surprising to see volcanic activity anywhere in the penninsula. Only
place it is less likely to be seen is in the batholith area in the north.

There are some seismographs on the summit.
At least as reported by some guys who climbed the peak in 2000. Makes for a good trip report, if you have the time to read the whole log 
| Quote: | The Reforma 2000 Expedition will be carried out in two trips–one in January, and one in May to Baja California, Mexico. The goal of the January trip
was to visit as many destinations as possible and lay the groundwork for research in May, when more detailed scientific fieldwork will be completed.
In the end, the team hopes to gain a better understanding of the volcanic hazards and approximate ages of these significant volcanoes. The
expedition is funded by the National Geographic Society’s Committee for Research and Exploration.
.....A couple of hours later, as the sun was setting over the Pacific Ocean, Keith, Brian and I scrambled to the summit and set up camp amidst the
palmetto trees. An aluminum cross with a bust of Jesus Christ, with an inscription for the miners of Santa Rosalia marked the summit shelf, a flat
area 3 meters by 3 meters. On the summit, and a nearby peak, broadcast towers transmitting seismic information stood 10 meters high. When we’d walk
by, an electronic noise would transmit data to a computer somewhere on the globe--probably at the University of Mexico...... |

buenos dias todos...well we are still here and posting although we just had the first quake of the morning...Sirena is safe in Guerrero Negro and even
though I thought it was funny a few days ago, we slept in the car last night with all the emergency gear including life jackets. The scientists are
due to arrive any minute and we have been informed that the ephicentre??? is here at the point so I want to show them where I saw smoke or steam
escaping from the cliff yesterday during the biggest one. Most of the village evacuated and others slept in tents and cars, some on the baseball field
out of town. On the radio just now it claims it is movement of a plate 150 miles offshore by Abreojos??? They said there are NO sites with equipment
to register anything near here which is why nothing shows up on the sites. I guess we will find out today just where this nasty thing is coming from.
But I'm ready to jump in the car and go but want to talk to the specialists too. Our house has lots of cracks now in all the rooms. There were more
than 30 quakes from 4:00 yesterday till now....whew....so I'm not sure how long I'll be here folks but just wanted to post this to all ;those
wondering what's up....basically we don't know diddily squat except its shaking like mad every little while. hasta pronto I hope...

understand where Asuncion is

It sure sucks that nobody has come to check this thing out sooner...I just heard on the radio that the earthquake folks in La Paz heard it on the
radio!! We've been calling since thursday but no response from anyone. But after yesterdays big show...it's getting more attention now.

I am so sorry this is happening. Wish I could help more.
Be sure to take your family pictures and important papers with you. These are the items that people most often forget to bring with them in
evacuations.
I hope that this will resolve soon and that you can get your life back.
There is an active Volcano that has grown for decades in a Mexican pasture that has never violently exploded, just grew from an anti hill into a
mountain.
Thanks for letting us know what is going on, we are worried about you.
Please let us know that you are safe and if there is anything we can do.

Some more info on the volcano
| Quote: | The volcano’s last strong eruption – with lava and stones – was reported by Fathers Consag and Rodríguez in May-June 1746; in 1857, the volcano
spewed a lot of steam
link
|
| Quote: | The Tres Vírgenes volcanic complex contains the only large stratovolcanoes in Baja California. The roughly 1940-m-high complex rises above the Gulf of
California in the east-central part of the peninsula. Three volcanoes, El Viejo, El Azufre, and La Vírgen were constructed along a NE-SW line and are
progressively younger to the SW. The youngest volcano, La Vírgen, is an andesitic stratovolcano with numerous dacitic lava domes and lava flows on its
flanks
A major plinian explosive eruption from a SW-flank vent took place about 6500 years ago and was followed by effusion of a thick lava flow. An
ash plume was reported from Tres Vírgenes volcano by a Spanish Jesuit priest while navigating the Gulf of California in 1746, but no deposits from
such a young eruption have been found.

Nothing on the Pacific side near Shari's is shown... This is not part of Tres Virgenes or La Reforma.... Something right UNDER Asuncion is active.
Shari, keep your camera with you and if you see any ground cracks with steam or smoke take both close up and wide angle, with background so we can get
perspective.
Thanks and be safe.

Sorry David, my bad.
Here is a map of Asuncion. So we all know where this is occurring.

I have to stay cause David wants pictures!  We are ready to evacuate..apparently
bigger shakes happen in the afternoon as the ground heats up....uh huh..there is so much gossip flying around...but I would like to be here to find
out from the specialists...they are bringing apparatus also to detect tidal waves etc. No bajamatic....this isn't my way of drawing attention to
asuncion

I can tell you right now that you don't want to put much trust or base you decisions on what a couple of guys from La Paz are going to tell you.

When the ground moves and starts steaming, it's time to head for parts unknown. Return when things settle down. It'll either be there
when you return or it won't.
