Arenal volcano viewed from OVSICORI-UNA webcam, 8 June 2011.

Even in Costa Rica, a land well-provided with active and spectacular volcanoes, Arenal stands out as something special. It’s now possible to keep a close watch on Arenal via a new webcam installed by the Observatorio Vulcanológico y Sismológico de Costa Rica (OVSICORI-UNA). It is located to the south of Arenal 1.4 km from the summit and, weather permitting, gives a fine view of the volcano’s elegant cone. The image is available via this page (or click on the image above) and refreshes every 10 seconds. Be careful — volcano webcams can be addictive!

The Global Volcanism Program has put together a bumper Weekly Volcanic Activity Report for 8-14 September 2010. Sally Kuhn Kennert of the GVP compiled the report. Some highlights:

  • Nevado del Huila: alert level raised following increase in seismicity and gas/ash emissions
  • Soufrière Hills: several small-to-moderate pyroclastic flows descended the dome and took parts of it down with them
  • Arenal: rumbled its way through August with gas emissions, strombolian eruptions and avalanches
  • Sinabung: threw ash plumes up to 4.3-4.6 km altitude

Arenal activity continues, tourists dice with death 17 April 2009

Seismicity at Arenal volcano in Costa Rica remains elevated, with continuing rock-fracture earthquakes caused by magma movement within the volcanic system (online seismograph displays for Arenal, along with other Costa Rican volcanoes, are available from the Observatorio Vulcanológico y Sismológico de Costa Rica: Sismogramas en línea). Monitoring was stepped up at Arenal at the beginning of this month, and warnings were issued to tourists visiting the Arenal National Park over the Easter holiday.

It seems to have made no difference, however. The Costa Rican newspaper La Nación reports today that Costa Rican and foreign tourists ‘are entering dangerous areas in the vicinity of the crater of Arenal volcano, despite the presence of notices warning of the increased seismic activity that could cause avalanches’. Visitors have apparently been getting in via neighbouring private property to evade police and park ranger controls, or are being brought into the park by people masquerading as official guides in order to earn money, regardless of the risks. ‘Because [the tourists] are uninformed or unconcerned, they are wandering through the area of greatest danger. They are putting their lives on the line’, warns the head of the tourist police, José David Rojas.

Arenal and its surrounding park form a popular tourist attraction, but the volcano is not tame and has to be treated with respect. In August 2000 three people died on Arenal when they were engulfed by a pyroclastic flow: they were in an area identified as dangerous at the time.
