In 2004, a tsunami swept over certain parts of Southeast Asia, which extended up to Africa. More than 200,000 people perished with some bodies never identified or recovered.
The incident is not the first but one of many that have happened over the centuries. It is not only in the Pacific but also in the Atlantic and the Indian Ocean, which makes it everyone's concern.
History shows that tsunamis have occurred dating from 1600 B.C until the present with the latest in July that killed more than 600 people in the island of Indonesia.
Until now, the exact location where tsunamis will strike cannot yet be predicted. Once an underground earthquake occurs, an alert is sent to coastal communities that something could go in that direction.
Since the Pacific is known throughout the world as the ring of fire due to the numerous underwater volcanoes, it is only right that a tsunami emergency alert system is in place to prepare people for the worse.
The tragic event that took place almost two years ago never had such a system. It was only after that regional governments decided to come up with one to prevent it from happening again.
The alert system is made up of four things. This is namely information, advisory, watch and warning.
When an underground earthquake has been detected, the Pacific Tsunami Warning Center based in Hawaii will issue the news to the countries in the region. Since the impact is not yet known, an advisory will be sent about possible areas that will be hit.
There is a saying that goes, " it is better to be safe than sorry." The prediction may not happen but this is better than having a lot of casualties because the no warning was reported.
The after effects of the underwater earthquake may take hours but everyone knows that the tsunami is coming.
This is the time that people in the coastal communities should watch over the water. If it recedes, then a warning will be given to everyone that a mandatory evacuation must begin.
A siren is usually used to inform everyone. This will sound at different times starting from three hours before impact until half an hour before the tidal waves are supposed to hit the beach.
During this time, residents should already begin moving out of the danger zone. People can go deeper inland or run to the hills. It will be a good idea to bring water, food and clothing. Packing a light transistor radio will also be helpful to be able to stay informed when it is safe to come down.
The tsunami emergency preparation does not end when the reports predict that it is on the way. People will still be there monitoring the situation to issue a warning cancellation if nothing happened or if it is safe to return.
Countries that live in the Pacific Rim of Fire must coordinate with each other to minimize the loss of life. This is because it is much easier to rebuild and impossible to replace someone who died.
Community leaders should hold exercises to time how long it takes to evacuate the area so that everyone will be ready when the real thing hits the shores. A headcount can be done to find out if there are any people still missing should the inevitable strike.
Preparing For An Emergency Volcano Eruption
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.
