Recheshnoi reported activity



Event Name : Geyser Bight 2013

Start: 2013 Observed
Stop:July 2015 Observed

Seismicity with no confirmed eruption: BibCard
Eruption Type:Not an eruption.

Description: From Dixon and others, 2017: "The Geyser Bight Valley is a geothermal area (Nye and others, 1992; Motyka and others, 1993) southeast of Mount Recheshnoi (fig. 21 [original text]). In 2007, the seismograph network on neighboring Okmok Caldera recorded a short earthquake swarm in October. Following a 5-year period of quiescence, seismic activity increased in the Geyser Bight area in 2013 and continued through July 2015. The vast majority of the earthquakes located in 2015 were at shallow depths, less than 7 km (4 mi) with earthquake magnitudes between ML= 0.5 and ML=1.5. Seven earthquakes were larger than ML=2.0; the largest earthquake was a ML=3.0 event on June 30. Because this sequence of earthquakes occurred well away from a historically active volcano, no change in the alert status was made at any neighboring volcanoes."
