Kick’em Jenny Alert Levels

The Alert Level for the Kick’em Jenny reflects the status and activity of the volcano. It consists of four levels, increasing in severity: green, yellow, orange, and red.

This alert level system outlined in this article is for Kick ’em Jenny ONLY. Alert levels for volcanoes on land are defined slightly differently.

What triggers an Alert Level Change?

According to the University of the West Indies Seismic Research Centre, Kick’em Jenny is neither visible nor audible until it is in full eruption so that one of the most useful volcanic monitoring techniques – visible inspection – is not possible.

Kick’em Jenny has been in a state of continuous low-level activity since 1939 at least and it can be dangerous to spend time directly over the volcano.

The Alert Levels

Green Level

What does this mean?

The Kick’em Jenny Volcano is quiet. Seismicity and fumarolic (steam vent) activity are below the historical level at the volcano. No other unusual activity detected.

This is level one of four, the lowest level.

Actions for Scientists

Maintain the basic monitoring system.

Recommended action by Civil Authorities and the Public

Yellow Level

What does this mean?

The Kick’em Jenny Volcano is restless. Seismicity and/or fumarolic activity are above the historical level or other unusual activity has been observed or can be expected without warning. This is level two of four.

Actions for Scientists

  • Bring the monitoring system to full capability.
  • Civil authorities will be alerted and the communication system tested.

Recommended action by Civil Authorities and the Public

  • Intensify public awareness campaigns.
  • An exclusion zone of 1.5 kilometers from the summit of the volcano should be enforced for non-essential shipping.
  • Visiting scientists should ensure that the Sauteurs Observatory is manned throughout their visit (at their expense) and that the Observatory can contact their ship at any time. They must also be prepared to leave the exclusion zones immediately upon request.
An exclusion zone of 1.5 kilometers from the summit of the volcano should be enforced for non-essential shipping when a Yellow Alert Level is in effect for Kick'em Jenny.
An exclusion zone of 1.5 kilometers from the summit of the volcano should be enforced for non-essential shipping when a Yellow Alert Level is in effect for Kick’em Jenny.

Orange Level

What does this mean?

There is a highly elevated level of seismic and/or fumarolic activity or other unusual activity. An eruption may begin with less than twenty-four hours notice. This is level three of four.

Actions for Scientists

  • All regional governments alerted through Disaster Coordinators and Venezuelan diplomatic missions.
  • Sauteurs Observatory continuously manned.
  • Continuous communication with NaDMA. (Grenada and St. Vincent and the Grenadines).
  • Summit area under continuous visual surveillance.
  • Scientists and emergency personnel within exclusion zones maintain continuous contact with the Observatory.

Recommended action by Civil Authorities and the Public

  • Vulnerable communities advised of evacuation routes and transport put on standby.
  • Local radio stations in Grenada, St. Vincent, Barbados, and Trinidad placed on alert.
  • Public listens to local radio continuously for updates and visits the Seismic Research Centre website if possible.
  • All shipping stays outside the first exclusion zone (1.5 kilometers from the summit).
  • Non-essential shipping (pleasure craft etc) stays 5 kilometers clear of the summit (second exclusion zone).
  • Visiting scientists who are not taking part in essential monitoring are regarded as non-essential.
An exclusion zone of 1.5 kilometers from the summit of the volcano for all shipping and a 5 kilometer exclusion zone for non-essential shipping when an Orange Alert Level is in effect for Kick'em Jenny.
An exclusion zone of 1.5 kilometers from the summit of the volcano for all shipping and a 5 kilometer exclusion zone for non-essential shipping when an Orange Alert Level is in effect for Kick’em Jenny.

Red Level

What does this mean?

There is a highly elevated level of seismic and/or fumarolic activity or other An eruption is in progress or may begin without further warning. This is the highest level of alert, four of four.

Actions for Scientists

  • Measurements within the exclusion zones as permitted by activity.
  • Aerial reconnaissance whenever possible.

Recommended action by Civil Authorities and the Public

  • Vulnerable areas prepared for immediate evacuation.
  • All shipping stays 5km clear of the summit (i.e. out of the first and second exclusion zones).
  • The public in all vulnerable zones should listen to local radio stations for updates.
An exclusion zone of 5 kilometers from the summit of the volcano for all shipping when a Red Alert Level is in effect for Kick'em Jenny.
An exclusion zone of 5 kilometers from the summit of the volcano for all shipping when a Red Alert Level is in effect for Kick’em Jenny.

Who is responsible for adjusting the Kick’em Jenny Alert Level?

The U.W.I. Seismic Research Centre is a scientific monitoring agency that supports various local disaster management agencies of the Eastern Caribbean. This includes the monitoring of Kick’em Jenny volcano.

The Seismic Research Centre (SRC) updates the National Disaster Management Agency of Grenada (NaDMA) which is then responsible for adjusting the alert level of Kick’em Jenny based on the SRC’s information.

The alert levels for volcanoes in the Commonwealth Caribbean are set by a committee which consists of the professional scientific staff of the SRC, although they often consult with other scientists with special knowledge of this region. Governments with responsibility for the volcano in question are consulted before the alert level is changed but this may not always be possible as alert levels may change very rapidly.

What triggers an Alert Level Change?

The purpose of the alert levels are to reflect the status of the volcano at any given point in time. Since 1939, Kick’em Jenny has remained in a state of unrest, meaning it has been at Yellow Level.

On average, Kick’em Jenny produces approximately one to two earthquakes per month. During periods of elevated seismicity, the number of seismic events can increase to 10’s and even 100’s, raising the Alert Level to Orange or Red.

As of June 2020, the last time the Alert Level changed was in March 2018. Beginning March 9th, 2018, the UWI SRC began to detect higher than average seismic events occurring. This elevated seismicity continued to intensify, becoming 10’s of earthquakes recorded over the 10th – 11th March. Overnight 11th March to 12th March, seismicity intensified further, which triggered the change in alert level from Yellow to Orange.
