Missouri, USA – Flooding along the Meramec River near St. Louis has closed one major interstate and is threatening a second and hundreds of smaller roads and highways. That would cut off thousands of workers from getting to work and school. More than 200 homes have been damaged, and St. Louis County’s emergency management chief says another 1,500 are in harm’s way. The Meramec and other rivers in Missouri and Illinois rose sharply after significant rain in the past few days.

Louisiana, USA – A rainstorm dumped over 10 inches of rain in less than four hours on parts of Avoyelles, flooding homes, businesses and farmland throughout the parish. Approximately 100-125 homes were flooded and several roads were closed.

Lake Ontario, USA – The Lake is at its highest level in 24 years, roughly 20 inches above average, because of near-record spring rains. Waves are crashing over breakwalls and flooding hundreds of properties along the lake’s southern and eastern shores. Owners of lakeside homes are piling sandbags against the floodwaters.

Disease

Colombia: Leishmaniasis outbreak

Health officials have issued an epidemiological alert for the city of Neiva, located in south central Colombia due to a leishmaniasis outbreak, according to a La Nacion report (computer translated). The alert, issued on Apr. 26, came after a number of people became infected, including a four-month-old baby who died from the parasitic infection. In addition, of the approximately 1000 dogs from the street tested for the parasite, 500 turned out infected. The infected dogs were sacrificed, according to the report.

Roundup of Global Volcanic Activity – New Activity for the week of 26 April-2 May 2017

Aira | Kyushu (Japan) : JMA reported that there were less than 10 small events at Showa Crater (at Aira Caldera’s Sakurajima volcano) during 26-27 April, the first eruptions at that crater since 26 July 2016. During 28 April-1 May there were 16 events, of which two were explosive, ejecting tephra up to 800 m from the crater. One of the explosive events, at 1101 on 28 April, generated an ash plume that rose 3.2 km above the crater rim. The Alert Level remained at 3 (on a 5-level scale).

Ibu | Halmahera (Indonesia) : Based on PVMBG observations and satellite images the Darwin VAAC reported that during 26-27 and 29-30 April ash plumes from Ibu rose 1.5-1.8 km (5,000-6,000 ft) a.s.l. and drifted E, NE, and N.

Kambalny | Southern Kamchatka (Russia) : KVERT reported that moderate levels of activity at Kambalny continued during 21-28 April. The Aviation colour Code remained at Orange.

Langila | New Britain (Papua New Guinea) : Based on analyses of satellite imagery, the Darwin VAAC reported that on 26 April and 2 May ash plumes from Langila drifted E and NE at an altitude of 2.1 km (7,000 ft) a.s.l.

Manam | Papua New Guinea : RVO reported that periods of Strombolian activity at Manam’s Southern Crater were observed during 24-30 April, and roaring and rumbling was heard. Explosions were also heard and sometimes followed by detectable shock waves. Most incandescent tephra fell back into the crater but some were deposited in the SW and SE valleys. Strombolian activity declined for a period on 25 April, and only dense gray ash plumes were seen rising from the crater. Activity was lower during 26-27 April. Strombolian explosions returned on 28 April; some of the explosions were strong and rattled nearby houses. One strong explosion and banging was heard at the Bogia Government Station. A period of moderate to moderately-high Strombolian activity was detected during 0200-0330 on 30 April. A small pyroclastic flow traveled down the SW valley, stopping around 200 m a.s.l. Scoria (up to 40 mm in diameter) and ash fell on the E side of the island in Abaria and Boakure.

Poas | Costa Rica : OVSICORI-UNA reported that during 30 April-1 May seismicity at Poás was characterized by volcano-tectonic events, long-period events, and low-amplitude tremor. A larger event was recorded at 0621 on 1 May, though there was no other confirmation of an eruption.
