2016-04-25 03:34:28 - Volcano Eruption - Nicaragua | | | EDIS Code: | VE-20160425-53048-NIC | | Date&Time: | 2016-04-25 03:34:28 [UTC] | | Continent: | Central-America | | Country: | Nicaragua | | State/Prov.: | Chinandega Department, | | Location: | San Cristobal volcano, | | City: | | | Not confirmed information! | |  | | Description: | | The volcano had a series of new explosive eruptions on Friday, producing ash plumes that rose up to approx. 2 km above the summit crater, drifted south and caused moderate ash fall in areas up to 10-15 km south and southeast of the volcano, including Las Brisas, Santa Narcisa, and Chichigalpa town. The new series of eruptions began on 22 April around 10:20 local time with a first explosion, followed immediately by a stronger one (image). Weaker explosions followed intermittently throughout the day, but activity seems to have faded again as of today. Whether these eruptions were caused by superficial steam explosions (phreatic activity) or involved new magma that has risen inside the volcano's conduit is unknown at the moment (without analysis of the ash and seismic and other parameters). In any case, the volcano has been at elevated unrest for some time and might continue to do so for a while: unconfirmed minor explosions seem to have occurred earlier this year in February and similar, more significant explosions took place in March and June last year (2015). | | | | |  |  |
