turrialba volcano eruption 2019

Ash plumes rose as high as 2 km above the crater and drifted NW. Turrialba volcano (Costa Rica): activity updates and eruption news Turrialba Volcano Volcanic Ash Advisory: NEW VA EMS. The temperature of summit cracks was 94°C. At 1400 the webcam recorded strong emissions of gas, vapor, and tephra from Cráter Oeste. Based on a news report, there were more than 200 explosions recorded during 29 April-2 May; an explosion at around 0600 on 2 May produced an ash plume that rose 2 km high. Another event was recorded at 1620 on 12 October but weather conditions obscured views of any resulting emissions.

An explosion at 1710 on 24 October produced an ash plume that rose 800 m above the crater and drifted SSW. The volcano emitted ash on 58% of the days during the year. Several neighborhoods in San José and Heredia reported ashfall and a sulfur odor. During January-September 2014, volcano-tectonic (VT) seismicity was generally stable (at 3 or fewer events per day)(figure 41, right plot).On 28 July 2014, a swarm of small, low-amplitude, short-duration, and high-frequency events lasted two hours.

At 0800 on 8 October an event produced an ash plume that rose 500 m above the crater and drifted N. OVSICORI-UNA reported that at 0915 on 27 September an event at Turrialba produced a passive ash plume that rose 200 m above the crater and drifted NW. Periods of volcano-tectonic and long-period events were also recorded. Carr M J, 1984. At 0812 a gas-and-ash plume rose 500 m above the active craters. Another event at 1025 on 28 August produced a plume that rose 300 m and drifted NW.OVSICORI-UNA reported that an event at Turrialba at 1012 on 21 August generated a plume that rose 200 m above the crater rim and drifted NW. Some of the fumaroles correspond with two fractures. Tremor was constant but had a low amplitude. Winds carrying toxic gases 10 km SW, to the S side of Irazú volcano, caused trees to exhibit mild burns to a greater degree than effects from the previous year. In contrast, ash erupted during 4-5 January 2010 yielded leachate with pH 6.7-7.1 (near neutral). The emission drifted towards the Valle Central. Turrialba volcano (Costa Rica): activity updates and eruption news latest ( 2020 ) | | 2019 | Nov-Dec 2018 | Sep-Oct 2018 | archive Apr-Aug 2018 | Feb-Mar 2018 | Jan 2018 | Sep-Dec 2017 | … Ashfall was reported in areas of Valle Central (30-40 km W), including Coronado, Guadalupe, and Heredia (38 km W). Minor ashfall and a sulfur odor was reported in areas of San José including Rancho Redondo, Goicoechea, Moravia, San Pedro Montes de Oca, and Guadalupe.OVSICORI-UNA reported that during 20-25 June seismicity at Turrialba was characterized by low-to-medium amplitude tremor, and a small number of low-amplitude volcano-tectonic and long-period events.

Several elongated fissures were documented on the rim S of the W crater, as well as 1 km downslope to the NW. The UNA seismograph (VTU) 0.5 km E of the main crater recorded 14 low-frequency events in August.Only 13 low-frequency events were recorded in September by UNA station VTU, 0.5 km E of the main crater; three occurred on 29 September.Fumarolic activity continued on the N, W, and SW walls of the main crater, at temperatures of about 90°C. Ashfall was reported in a number of communities including San Rafael de Moravia (31 km WSW), Sabana (38 km WSW), Buenos Aires (17 km N), and Pococí (45 km N) during 2-3 June. Events at 0023 and 0700 on 2 August generated diffuse ash plumes that rose 1 km and 300 m, respectively, and drifted W. An event at 1600 on 4 August produced a diffuse ash plume that rose 300 m. OVSICORI-UNA reported that during 23-31 July activity at Turrialba was characterized by sporadic, passive gas-and-ash emissions detected almost daily. On 19 March at 0806 and 1007 gas and water vapor emissions rose from the crater; the emissions at 1007 rose from Cráter Central and contained a small amount of ash. Small explosions were detected at 1804 and 2147 on 15 September.

In general, the plumes did not rise more than 500 m above the crater, and a few were accompanied by small pyroclastic flows. Gases were emitted from cracks on the S external wall and burned vegetation was noted. The local Tobias Bolanos airport (40 km WSW) closed intermittently. Their origin was possibly related to a local fault.OVSICORI-UNA continues to monitor Turrialba's seismicity. At 1549 a third ash emission drifted NNW at an unknown altitude due to cloudy conditions. On 10 June at 0830 an explosion generated an ash plume that rose 500 m above the crater. The temperature of summit cracks was 94 degrees Celsius. An event at 0801 on 30 December produced a dense and passive emission of ash that rose 300 m above the crater and drifted SW. An event later that same day, at 2001, produced a plume that was not visible. A very low and diffuse ash plume rose from the crater on 24 July, causing ashfall in Coronado, Tibás (35 km WSW), Goicoechea (28 km WSW), Moravia (31 km WSW), and other areas in the Valle Central.OVSICORI-UNA reported that an event at Turrialba at 0930 on 28 May generated a plume that rose 300 m above the crater rim and drifted SE.OVSICORI-UNA reported that an event at Turrialba at 0900 on 21 May generated a plume that rose to an unknown height due to poor visibility.
