अप्रैल 21, 2013 ज्वालामुखी गतिविधि

यह (लगभग) दैनिक पोस्ट करने के लिए दुनिया भर में ज्वालामुखी की गतिविधि में परिवर्तन का पालन करना चाहता है.
इस पोस्ट में के भूविज्ञानी Rodger विल्सन जो ज्वालामुखी seismicity और आर्मंड Vervaeck के माहिर ने लिखा है. अगर हम इसके बारे में नहीं लिखे हैं तो कृपया हमें नई या परिवर्तित गतिविधि के बारे में बताने में संकोच न करें। -

अप्रैल 21, 2013 ज्वालामुखी गतिविधि

Strong seismicity continues at नेव्हाडो डेल Ruiz volcano (Colombia) (station OLLZ) today. Just as in previous days, volcano-tectonic earthquakes diminished in number through last night (although volcanic tremor amplitude increased) and then, following a magnitude M2.9 event this morning, resumed at its previous high level.

Another earthquake swarm, episode, pulse, whatever you wish to call it, is underway at न्यूबेरी volcano (Cascade Range) (OR) (station CPCO). This pulsatory seismic behavior has affected the volcano for nearly two weeks.

Seismicity has increased again at सान क्रिस्टोबाल (Nicaragua) (station CRIN) and neighboring Telica (station TELN) volcanoes. Frequent low-magnitude volcanic earthquakes now merge into low-level volcanic tremor from time to time at the volcano. At Telica volcano, volcanic earthquake magnitudes have lessened, but event frequency is very high at this time.

कहीं और, ...

KVERT reports no change in seismic/eruptive behavior at the five active Kamchatkan ज्वालामुखियों: Tolbachik, Bezymianny, Sheveluch, Kizimen and Karymsky. Moderate seismicity affects hydrothermally active Gorely volcano.

Hybrid earthquakes, small explosions, rockfalls and pyroclastic flows continue at a high level at कोलीमा ज्वालामुखी (मैक्सिको)। पर गतिविधि Popocatepetl volcano has diminished the past two days. Exhalations of gas (and occasional volcanic ash and blocks) now occurs only about once every two hours on average. The Popo seismogram shows only low level volcanic tremor at the volcano today.

Periods of more explosive activity have occurred this morning at both Fuego (ग्वाटेमाला) (स्टेशन FG3) और Pacaya (station PCG) volcanoes. Activity at Santiaguito Dome Complex (सांता मारिआ volcano) remains mostly internal (in the form of numerous hybrid earthquakes), but local inhabitants reported hearing jet-like noises coming from the volcano overnight.


सतत ज्वालामुखी कंपन में Masaya volcano (Nicaragua) (station MASN) is slowly returning to background level.

Small earthquakes, rockfalls and degassing events (with ash?) are visible on seismograms recorded at Galeras ज्वालामुखी (कोलंबिया) (स्टेशन CUVZ) आज।

को-इरप्टिव (?) सीस्मैसिटी अधिक रहती है Reventador volcano (Ecuador) (station CONE). Another episode of small earthquakes (volcanic? glacier?) affects Cotopaxi ज्वालामुखी (स्टेशन CO1V).

Continuous volcanic tremor remains unstable at व्हाइट द्वीप ज्वालामुखी (न्यूजीलैंड).


OMI satellite were not updated again today. No volcanogenic "hotspots" were imaged by MODIS satellite thermal sensors today.
