MERS coronavirus 2020

Since the beginning of the year, 61 total Middle East respiratory syndrome coronavirus (MERS-CoV) cases have been reported through October 6, mostly in Saudi Arabia. No new cases have been reported in several months. Of the 61 cases, 57 were reported from Saudi Arabia.

COVID-19 Immunity

People who survive serious COVID-19 infections have long-lasting immune responses against the virus, according to a new study led by researchers at Massachusetts General Hospital (MGH). The study, published in Science Immunology, offers hope that people infected with the virus will develop lasting protection against reinfection.

Volcanos

Roundup of Global Volcanic Activity – Ongoing Activity for the Week 30 September 2020 – 6 October 2020

Aira | Kyushu (Japan) : JMA reported that very small eruptive events at Minamidake Crater (at Aira Caldera’s Sakurajima volcano) were occasionally recorded during 29 September-3 October. Crater incandescence was visible at night. An eruptive event at 1635 on 3 October produced a plume that rose 1.7 km above the crater rim. The Alert Level remained at 3 (on a 5-level scale).

Dukono | Halmahera (Indonesia) : Based on satellite and wind model data, and information from PVMBG, the Darwin VAAC reported that during 30 September-6 October ash plumes from Dukono rose 1.8-2.4 km (6,000-8,000 ft) a.s.l. and drifted W N, NE, E, and SE. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km exclusion zone.

Ebeko | Paramushir Island (Russia) : Volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, observed explosions during 25-26 and 30 September and on 1 October that sent ash plumes up to 3.5 km (11,500 ft) a.s.l. and drifted SE and E. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Kadovar | Papua New Guinea : Based on satellite data, the Darwin VAAC reported that on 4 October discrete ash puffs from Kadovar rose to an altitude of 2.1 km (7,000 ft) a.s.l. and drifted NW.

Kikai | Japan : JMA reported that at 0757 on 6 October an eruption at Satsuma Iwo-jima, a subaerial part of Kikai’s NW caldera rim, generated a volcanic plume that rose 200 m above the Iodake crater rim. The Alert Level remained at 2 (on a 5-level scale).

Langila | New Britain (Papua New Guinea) : Based on analyses of satellite imagery and wind-model data, the Darwin VAAC reported that on 5 October an ash plume from Langila rose to an altitude of 1.8 km (6,000 ft) a.s.l. and drifted NW.

Raung | Eastern Java (Indonesia) : PVMBG reported that eruptive activity at Raung continued during 28 September-4 October with white-and-gray plumes rising 100-400 m above the crater rim. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km exclusion zone.

Rincon de la Vieja | Costa Rica : OVSICORI-UNA reported that small, frequent (1-2 events per day) eruptions at Rincón de la Vieja continued to be recorded, though sometimes not visually confirmed, during 30 September-6 October. Eruption plumes often rose 500-800 m above the crater rim but on 1 and 6 October they rose 1 km.

Semeru | Eastern Java (Indonesia) : According to PVMBG ground-based observers noted ash plumes rising 700 m above Semeru’s summit and drifting SW on 30 September. An ash plume rose 600 m and drifted S at 0509 on 2 October. The Alert Level remained at 2 (on a scale of 1-4).

Sheveluch | Central Kamchatka (Russia) : KVERT reported that a thermal anomaly over Sheveluch was identified in satellite images during 25 September-2 October. A new lava block (named “Dolphin”) that extruded from the E part of the lava dome was first visible on 28 September. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Suwanosejima | Ryukyu Islands (Japan) : JMA reported nighttime incandescence at Suwanosejima’s Ontake Crater during 25 September-2 October. Eruptive activity was intermittently recorded along with nine explosions. Ashfall was periodically reported in Toshima village, 4 km SSW. An explosion at 0822 on 26 September generated a gray-white ash plume that rose 2 km above the crater rim. At 2028 on 27 September an explosion ejected blocks 400 m from the crater. The Alert Level remained at 2 (on a 5-level scale).

Villarrica | Chile : SERNAGEOMIN reported that a long-period (LP) event and associated explosion were recorded by Villarrica’s seismic network at 1130 on 4 October. A grayish plume was visible rising above the crater rim. At 1343 and 1347 on 5 October there were two LP events and associated explosions; each generated ash plumes that rose as high as 400 m. The Alert Level remained at Yellow, the second lowest level on a four-colour scale. ONEMI maintained an Alert Level Yellow (the middle level on a three-colour scale) for the municipalities of Villarrica, Pucón (16 km N), Curarrehue, and the commune of Panguipulli, and the exclusion zone for the public of 500 m around the crater.
