In Guatemala, the Pacaya volcano is in typical Strombolian activity, with incandescent ejections 25 meters high above the Mackenney crater. They feed two lava flows of approximately 250 meters.

The area is clear, with a temperate environment and little wind; the explosions are not audible.

Nevado del Ruiz - 23.03.2020 - ash emissions - SGC webcam

Nevado del Ruiz - 23.03.2020 - ash emissions - SGC webcam

In Nevado del Ruiz, ash and gas emissions were recorded on March 23 at 6:30 a.m., observed by web cameras installed in the volcano area and in Manizales.

The Colombian Geological Survey reports that earthquakes of low energy levels associated with low ash emissions have continued in recent days.

The direction of dispersion of the last emissions was governed by the direction of the wind, mainly to the northeast and southeast of the volcano, and a possible ash fall is expected in the area.

New earthquakes associated with gas and ash emissions are also not excluded.

The activity level continues in yellow or (III) / changes in the behavior of volcanic activity.

Merapi - 24.03.2020 / 6:16 am - Doc. Volcano YT i Frekom

The Merapi volcano, on Java, on alert level 2 / waspada, presents on March 23 a moderate to high white plume, with a height of 100-150 meters above the summit, drifting over a large eastern sector.

At the seismicity level, the PVMBG reports:

- 4 earthquakes linked to avalanches, with an amplitude of 2 to 10 mm and an earthquake duration of 13.5 to 43.16 seconds. The sliding distance and the direction of fall are not observed.

- 1 blast earthquake, with an amplitude of 4 mm and an earthquake duration of 15.7 seconds.

- 1 low frequency earthquake with an amplitude of 3 mm and an earthquake duration of 18 seconds.

- 16 hybrid earthquakes, with an amplitude of 2 to 10 mm, S-P 0.3 to 1.3 seconds and an earthquake duration of 5.6 to 10.4 seconds. (the increase in the number of hybrid earthquakes often announces a more important next activity)

- 1 distant tectonic earthquake with an amplitude of 6 mm, S-P 38.4 seconds and 99.4 seconds of duration of the earthquake.

Field Service Management has a crucial role in maintaining Network Field Engineer as they are responsible for planning, installing, testing, and maintaining the equipment to run a proper communication network. Their general duties include the maintenance and repair of equipment and construction of towers to ensure optimal performance. A telecom engineer’s job involves the use of various tools such as interconnect devices, network facilities, and radios. A field engineer also works with engineers from other fields for equipment installation and then report to the upper management.

A Field Service engineer should have some experience with telecommunication systems and at least a two-year degree for telecommunication field technician jobs. Telecom field engineering is a very demanding job because they have to work long hours and have to show up as soon as they receive a call when they’re not on the job. A field engineer also needs to work in high-stress scenarios and repair the equipment till the service is restored.
