Hi Sabrina - Here is our Cleveland Volcano activity page: https://www.avo.alaska.edu/activity/Cleveland.php CLCO is 15.5 km (9.6 miles) east of Cleveland. (this is the currently working station, at Concord Point) CLES is 3.4 km (2.1 miles) east of Cleveland. (this station is not currently working) You can see their locations on our interactive map: https://www.avo.alaska.edu/map/#-169.794:52.804:11 There is text about how we monitor Cleveland in every daily update or color code change.

From yesterday's report:

Cleveland volcano is monitored by only two seismic stations, which restricts AVO's ability to detect precursory unrest that may lead to an explosive eruption. Rapid detection of an ash-producing eruption may be possible using a combination of seismic, infrasound, lightning, and satellite data. The web camera, one seismic station, and the local infrasound array are offline due to a equipment failure on September 23rd. This hampers efforts to rapidly detect explosive activity; however, Cleveland remains monitored with a single seismic station and regional instruments. Hope this is helpful, Cheryl -------- Sabrina L. Perez Aviles wrote: I was wondering what type of monitoring the Cleveland Volcano in Alaska has. Some site state that there is a seismic station while others say it does not. I was wondering if it did have one and where its location is for a project I'm doing on this volcano. Also if there is other monitoring systems used it would be appreciated if I was informed as to which ones those are.
