Emergency Preparation Before Eruption of a Volcano

http://emergencypreparation-tips.blogspot.com/Volcanic eruptions are one of the powerful disasters nature can bring. Volcanic eruptions are catastrophic enough that it can wipe out several towns in a few hours. They can also cause temporary changes in the Earth’s climate.

Volcanologists are the scientists who study volcanoes. They predict the possibility of a volcanic eruption as well as the severity. However, Volcanologists can not always exactly forecast when and where the next volcanic eruption will occur. That is why, it is important to know the basics in on how to prepare for an emergency volcanic eruption.

1. First, you need to be at least familiar with the terms associated with volcanic eruptions. These will be very helpful in understanding news about volcanic eruptions.

Volcanic ash refers to small dust particles or large pieces of rocks which are erupted to the air and carried down together with volcanic gases. These volcanic ashes can corrode metals, decompose fabrics, clog machineries, block water intakes and drains, and of course kill vegetation.

Pyroclastic flows are those streams of molten volcanic rocks. These flow at hurricane velocity. Because of their high temperature and speed, they can destroy everything in their path.

2. Coordinate with your local emergency team to check for any areas in your region which are prone to pyroclastic flows and volcanic ash.

3. If the volcano is starting to show some signs of eruption, do not go anywhere near it. As mentioned above, Volcanologists could not precisely predict the time a volcano may erupt. You can get immediately killed by a sudden eruption.

4. Follow your local government’s advise when they say you need to evacuate. You should avoid lower areas, especially to those places downwind. Although high infrastructures, such as tall buildings can offer protection from volcanic ash, these are not enough shelter for rock debris and lava flows.

5. As much as possible, do cross a bridge because of the danger caused by mudflows. If you need to cross bridges, look upstream first and ensure that no mudflow is approaching. Take note that mudflows move faster than you can ever run.

6. If the volcano has started emitting volcanic ash, do not go outside until the ash has settled. Also, avoid opening any windows and doors in the house.

7. Once the air is clear, immediately remove any volcanic ash which may have settled on your rain gutters and roofs. Volcanic ash can be disastrous if they have thickly accumulated on your rooftops. In addition, these can cause severe respiratory diseases, especially to infants and old people with lung problems.

8. If you need to drive, avoid areas which have already been heavily covered with dust. Maintain a speed slower than 30 mph.

9. Of course, you need to prepare enough food and water to last for several days. You would also need spare batteries and dust masks. You can use extra clothing to cover your head and thin cloths to breathe with.

When news of volcanic eruption is out, be sure that you are always prepared wherever you maybe. Arm yourselves with enough knowledge to reduce the great impact that a volcanic eruption have. Always listen to the radio for updates and advice on how you can safely overcome this disaster.

Volcanic eruption preparations do not stop after the volcano has erupted. Once the disaster is over, there are a lot of cleanup operations needed. Recovering from a volcanic eruption takes a long time. Cooperation within your community is needed.

Emergency Preparation for Eruption of a Volcano

Volcanoes are truly fascinating features of nature. Most often, they are adored for beauty and wonder, like the perfectly structured cone of the Mayon Volcano in the Philippines and the monstrosity of Mt. Fiji in Japan.

Volcanoes are almost like beautiful mountains except for they become disastrous. Volcanoes are also mountains, but they are different in sense that the geothermal activity within them are active and are occasionally subject to destructive processes.

There are two kinds of volcanoes. One is dormant and inactive. Such volcanoes are like normal mountain and do not erupt. The other type id the destructive of the active volcanoes, which occasionally erupt.

Most volcanoes around the world are located at special zones that are strategically located around the Pacific Ocean. Thus, the areas around the Pacific are collectively known as the Pacific Ring of Fire.

The most destructive volcanoes are located in countries around the Pacific like Japan, Indonesia, the Philippines and New Zealand. Hawaii and other islands around the Pacific are also rich in volcanic supplies.

Volcanic eruptions

Through the years, people have seen the destructive potential of volcanoes. Many people have lost properties and loved ones to raging and molten lava that erupting volcanoes produce.

Often volcanic eruptions also accompany great and destructive earthquakes, making the disaster more catastrophic. Mudflow can also occur if there is rain over the crater of a volcano that is near eruption.

Preparing for volcanic eruptions

Fortunately, volcanic eruptions do not happen abruptly. That is because it would take some time before a volcano is able to accumulate enough lava that would trigger an eruption.

Often, there are indicators that are monitored before an eruption of a volcano. Natives and residents of nearby areas could also tell when an eruption is eminent.

Thus, volcanologists and seismologists would be able to advise people days or even months before the eruption of a volcano. The advice would serve as a warning.

When a warning is issued to an area, people are expected to take the necessary precautions so their lives could be spared from the forthcoming disaster.

Here are some emergency safety guidelines that could help you prepare for a volcanic eruption.

  • If your home is located within the few kilometers from the volcano, evacuate at once. You can opt to take your belongings with you or just leave them.
  • Earthquakes are normal occurrences when an active volcano is about to erupt so do not panic. Instead, proceed to doing the precautionary measures.
  • Sudden rains especially at the crater of the volcano would lead to an abrupt mudflow. The mud is not ordinary mud. It can contain pre-volcanic eruption debris and could be too hot that is enough to hard-boil an egg. Beware, or you may suffer from burns coming from mudflow.
  • When the volcano finally erupts, it may emit volcanic debris up in the air. Be prepared to see falling rocks and small stones coming from the crater. Thus, take a safe shelter during the eruption.
  • Prepare gas masks because the volcanic eruption may also be accompanied by foul odor coming from the release of sulfur. You may suffocate or may not be able to take normal breathing during a volcanic eruption.
  • Lava is the centerpiece of the eruption. It is also the most destructive material the volcano will produce during an eruption. It is composed of very hot mud that may instantly burn down any material. Avoid contact with the lava.
  • After the eruption, wait for volcanologists' advice on when you can safely get back to your homes.

Volcanoes are truly one of nature's most destructive forces. Be prepared for volcanic eruptions if you live nearby an active volcano. You do not need to change address. All you need is to take precautionary measures when the volcano produces signs of eminent eruption.

What to Do and How to Survive A Tsunami

Tsunamis used to be the stuff of movies and until it's devastation in Asia, most people didn’t think it was possible for tsunamis to occur in that magnitude.  With that realization, people have become aware of the risk and possible consequences of this natural calamity.

What is a tsunami?
Tsunamis are not caused by strong winds but by tectonic displacements (earthquakes, volcano eruptions, landslides) that occur on the seafloor.  Earthquakes that produce tsunamis are those that reach 6.5 or more on the Richter scale.  The average speed of the waves is 300 mph and can last from 5 minutes to an hour.

In open sea, tsunamis usually go unnoticed, having amplitudes of just 1 meter or even less.  However, in some situations, waves that enter shallow water can swell to several feet and in some rare cases, rise high enough to strike coastal areas with terrible force.

Who's at risk?
People who live in coastal areas located along or near the Pacific Ocean are most prone to tsunamis.  This area is most vulnerable because of seismic activity in what is called the Ring of Fire.  It has also occurred in Puerto Rico, Alaska, Hawaii and the Virgin Islands.

What to do in a tsunami emergency
When a strong earthquake is felt, leave the water immediately, get to shore and go as far away as you can from the beach, fast.  If your location allows it, go to a higher ground.  If the area you are in is mostly flat, go as far inland as you can.  If you can spot the wave, you are too close to escape it, regardless of its apparent distance.

Tune in to your local radio station, the weather radio or turn on the TV for news and updates.  They will inform you if there is a tsunami watch or warning issued in your area and where the emergency centers are.

Locate all members of your family and make sure everyone is informed.  Agree on a place to meet in case you're not together and make sure it's safe and as far away from the shore as possible.

If you have family members who have special needs like elderly people, small children or infants and those with disabilities, you might want to evacuate early.  You might also want to prepare your pets for moving, so bring emergency supplies for them as well.

Check your emergency supply kits and bring them with you.  It would be a good idea if they had been regularly restocked but if not, take what you can or get what is needed if you still have the time and opportunity.  Otherwise, opt to get water, food and extra clothes instead.

You might want to secure your house, but remember that this is the last priority.  Your life and that of your family's are the most important considerations during a tsunami emergency.  Expect items in your house to be swept away and if you could still secure them, do so.

Tsunami watch vs. tsunami warning
A tsunami watch is different from a tsunami warning.  A tsunami watch means that the presence of a dangerous tsunami is not yet confirmed or verified, although it is possible there is one.  It also includes predictions on what time the tsunami is expected and where it will possibly strike.

A tsunami warning means that there is a confirmed tsunami in your area and it could be close.  The warning will include the time at which the tsunami is expected and which areas are affected.
