Fiji Archipelago / Kadavu Island : Nabukelevu :

Kadavu Provincial Administrator and officials warn nearby villages to avoid landslide areas of Mt Washington.

The Kadavu Provincial Administrator and his officials are on the ground advising nearby villages and communities to avoid the landslide areas of Mount Washington in Kadavu and refrain from going out diving until further advise is issued by the National Disaster Management Office.
This has been confirmed by the Acting Commissioner Eastern, Inoke Tuiwainunu.
NDMO says the continuous seismic activity experienced in Kadavu since Sunday is currently being monitored by NDMO, the Mineral Resources Department and the Commissioner Eastern Division officials through the Provincial Administrator Kadavu.
Fijivillage has also received on the ground reports of aftershocks being felt by villagers in the area up until this morning.
Acting Director NDMO, Litiana Bainimarama says the safety of villagers and communities nearby is paramount and they will work closely with the Mineral Resources Department to assess the situation on the ground.

Mineral Resources Department Principal Technical Officer, Sakaraia Vunisa confirms they have been receiving reports of explosion-like noises and tremors through the media but will have to verify whether its happening throughout the island of Kadavu or only within the vicinity of Mt Washington.
Vunisa says it is best to get the actual assessment before a way forward is explored.
The Eliki Memorial School management has decided to close the school as they can see dust from the mountain.
Eliki Memorial School Head Teacher, Josua Rasoki says he closed the school from Monday for safety precautions and also because of the water pipes for the school was damaged during the earthquake.
Rasoki says they have felt tremors up until 7 o’clock this morning and this is a risk for students as it is the closest school to the mountain.

The andesitic-to-dacitic Nabukelevu lava-dome complex occupies the SW end of Kadavu Island at the S end of the Fiji archipelago. The high point of the complex is Mt. Washington, an andesitic lava dome. Flat-lying dacitic lava flows are found at Cape Washington along the W coast and at Talaulia Bay on the NE coast. NNE-trending faults cut the complex in several locations and define its E boundary. The dome complex is cut by several collapse scarps, which were the source of debris avalanches that have incorporated human artifacts and remains. Debris avalanches have entered the sea on the both the N and S sides of the volcano. Onshore and offshore deposits as well as native legends indicate that several eruptions have occurred during the Holocene. Block-and-ash flows related to dome growth have occurred within the past few hundred years.

The National Geological and Mining Service of Chile (Sernageomin) discloses the following PRELIMINARY information obtained from the monitoring equipment of the National Volcanic Monitoring Network (NVRN) processed and analyzed at the Volcanological Observatory of the South Andes (OVDAS) ):

Wednesday, October 23 at 15:35 local time (18:35 UTC), monitoring stations near the Nevados de Chillán volcanic complex recorded an explosion associated with an LP-type seismic signal with emission of gas and of materials. particulate.

The characteristics of the LP earthquake are as follows:
TIME OF ORIGIN: 15:35 local time (18:35 UTC)
LATITUDE: 36,856 ° S
LONGITUDE: 71,375 ° W

Guatemala , Santiaguito :

Volcano Special Bulletin
Updated by Jose Leonardo Quexel Hernandez on October 23, 2019 at 14:14 local time.

VOLCANO SANTIAGUITO.
LAHAR MODERE IN THE RAVINE OF RIO CABELLO DE ANGEL, TRIBUTARY TO RIO NIMA I.

The heavy rains on the upper domes of the volcanic complex of Santiaguito generate a descent of moderate lahar in the ravine of Rio Cabello de Angel, tributary of the Nimá I river. This lahar has the following characteristics: 15 meters wide, accompanied by tree branches and volcanic materials such as ashes and blocks 1 to 2 meters in diameter that vibrate the ground. Trained material was deposited by constant eruptive activity.
Because of the rains in the volcanic zone, it is therefore not excluded that lahars can be generated in the next minutes in the rivers San Isidro and Tambor, tributaries of the Samala River.

Therefore, INSIVUMEH recommends:
At SE-CONRED: Take precautions as there is a possibility of lahars in all the main ravines and other canals nearby, so it is necessary to inform the population not to stay in or near the ravines .
