Asian Tsunami

A day after the tsunami struck the coastal areas of southern Thailand, the manufacturer of Effective Microorganisms™ in Thailand, EM Kyusei gathered to discuss the possible ways to provide help to the affected areas. On the same day, Dec. 29th, Lt. Gen. Chinnarat of the Thai Royal Army (retired), advisor to the Science and Technology Committee of the Parliament and strong advocate for Effective Microorganisms®, contacted Mr. Kazuhiko Wakugami telling that the military has been requested by the Chairperson of the Thai Red Cross to use Effective Microorganisms™ in the affected areas.

Henceforth, on the same day, 2 tons of EM•1® was airlifted using the Thai Royal Air force plane to the affected area in Phang Nga Province, one of the hardest struck areas. They sprayed EM dilution at the temple, where dead bodies are placed temporarily for identification. There were more that 1,000 dead bodies at thetemple and Thai military is collecting the dead bodies from the disaster struck areas. They made activated EM (AEM) there and sprayed AEM every day at a dilution of 100, using, among other things, a 10 ton fire truck lorry and shoulder pack sprayers. There was a general comment among doctors, military people, and other volunteers that a 50% smell reduction was observed. There was initial protest over EM / AEM use from some forensic doctors, but after observing the smell reduction, all protests had stopped.

EM Kyusei knows that a more concentrated solution would have more effect. However, the initial problem is bringing EM into some of the inaccessible areas. At the request of the Red Cross, EM Kyusei provided 5 tons of EM on Jan 4. EM Kyusei staff brought the EM on land and with 10 staff members who are continuing work with volunteers as of this date.

In line with these issues, herewith are some practical suggestions for the application of EM® Technology for the rescue and remediation efforts in the disaster struck areas. It must be noted that these are temporary measures.

Salinity Control:
As the waves swept inland, many freshwater sources and soil areas have been mixed with the water from the ocean. This has left many farms such as rice paddies or shrimp ponds with extreme salinity. In order to reduce the salinity of the food production areas, the following are suggested.

Spray with EM® Activated Solution: The EM® microbes can absorb and store in their bodies the minerals brought in by the seawater and kept in the soil. The minimum recommended application is EM® Activated Solution diluted 1,000 times sprayed at 1 L/m2 at least once a week. If possible, it is also recommended to spread bokashi to the food production point (that is, farms or garden plots) to help the EM® and other local beneficial microbes increase in the area and hence reduce more quickly the salinity in the soil.

For Rice Paddies and Shrimp Ponds:

  1. Apply bokashi as suggested in the APNAN guidelines for land preparation
  2. Plant rice. This crop has a high salinity absorbing capability. It is expected that one cycle can help decrease significantly the salinity in the soil.
  3. Change water regularly as the usual practice in growing rice.
  4. In the case of areas where there is no water (as in a paddy), wheat, barley, etc. can be planted since these crops have high salinity absorbing capability.

Other Crops:
Watermelons and Melons could be planted. Application of bokashi as suggested in the APNAN guidelines should be followed.

Foul Odor Control:
There is much foul odor emanating from the decaying bodies. Spraying of EMAS, preferably at a dilution rate of 1:30-50 is suggested. For an area in general, spraying twice a day is also recommended to help reduce the chance of the spread of infectious diseases.

Foul Odor Control

Obtaining water for general use (not for drinking)

For Drinking Water:
Many military engineering corps have their own drinking water conversion and treatment systems. It would be much quicker to use such systems to obtain drinking water. Commercially available treatment systems are also available, such as reverse osmosis systems with 5 filter layer systems and can only filter about 550L per day and costs about 70,000 baht per unit (in the case of Japanese brands in Japan).

Nonetheless, a simple filter system can be made as follows:

If need be, a combination of Items 3 & 4 can also be recommended.

Obtaining water from open water sources, such as rivers, other freshwater / brackish water sources.

Obtaining water from open water sources, such as rivers and other freshwater bodies (for general purposes, not for drinking).

For Making of EMAS:

It is preferable to use clean/drinking quality water for making of the EMAS. However, in case it is difficult to obtain clean water, brackish water can be used. In the case brackish water supply is limited, brackish water (50%) and sea water (50%) can be used. The use of 100% seawater is not advised.

For Malaria Control in Freshwater Bodies:

It is possible for malaria and other waterborne diseases to break out from unclean freshwater sources. As countermeasure, the following are suggested:

  • Spray EMAS - Initial application: 1:2000 of water volume - Next applications: 1:5,000-10,000 of water volume
  • Apply mud balls (not bokashi balls) into the ponds at a rate of 1 pc/m2

It is expected that mosquito incidence will decrease significantly and larvae cannot develop.


  • Toilets: In the case of makeshift toilets, EMAS can be sprayed for foul odor control and suppression of pathogenic microbes.
  • Bath/shower alternative: Mix at least 1% of EMAS or EM•1® to water. Wet a hand
    towel and apply to the body. If 1% of EMAS is not effective, a more concentrated EMAS dilution, (up to 10%) is recommended. It must be noted too that the body of some people may initially react to the EMAS application. Itchiness, redness of the skin may be experienced. If it is too much to bear, it is recommended that the person stop this application.
Rainwater Collection Tank

Collected rainwater may be used for general purpose as well as for drinking.
